Sometimes I struggle to find something useful to say in this space, especially with a deadline looming. However, today (14 October) only one thing occupies my mind and that is the death of a beloved pet. Our family dog, April, died this morning after a short illness. It was a long night and a devastating loss for our family. She was almost 16 years old, so there were unspoken thoughts that her time was coming in the near future. Still, it is almost impossible to prepare for this reality, especially when it happens sooner than expected. But it is only dog, right? I've even thought that before, but never again. It will take me a long time to accept this loss. I can only say that she was part of the family. She was a gift for my daughter Sarah when she was seven years old and April has always been with us since; on car rides and walks; coast to coast car trips; and always on our annual holidays at Point Pelee. April at Point Pelee - 30 Some people ridicule the emotional attachment we have to our pets, drawing a broad distinction Sept 2018 - photo Sarah Lamond. between humans and animals. I don't think this way. Of course I value human life above a dog's, but consciousness is impossible to define and I firmly believe there is some degree of consciousness in dogs and many other animals. Obviously not the same as in humans, but there is something there. I will quote former HNC President Christine Bishop, "dogs are totally underrated in their ability to think, feel, bond, and anticipate change based on cues, just like us". "Science finds mammals, birds, and even the underrated reptilian phyla are more social and value kin associations so much more than we preferred to imagine just 10 years ago"(Amorello and smith 2012; Mayntz,2017). Perhaps if more people start to think this way there will be less mistreatment of animals in this world; and the mistreatment that goes on is absolutely appalling. I will get off my high horse here and wish everyone a successful Alan Wormington Fall Bird Count - your cue to get involved if you are not!

Three hundred and eighty-nine species and 78 subspecies of orthopteroid insects (Blattodea, Mantodea, Phasmatodea, and Orthoptera) have published records for the state of Texas. This is the first such comprehensive checklist for Texas and should aid future work on these groups in this area. Introduction (Flook and Rowell, 1997).

    August, 2014 ======Nothing Wildly Exciting Has Come in Yet but the Summer Is Not Over

    =========================================================================================== Vol. 18, No. 3 August, 2014 =========================================================================================== Nothing wildly exciting has come in yet but the summer is not over. A couple of notes from my backyard: The Japanese Beetle (Popillia japonica) population is down and as many as half the beetles have eggs of the parasitic fly Istocheta aldrichi on their backs. I pick beetles off my roses and raspberries leaving the parasitized beetles to produce more flies. What are others seeing for Japanese beetle populations? Secondly I have NO Lily Leaf Beetles (Lilioceris lilii) on my oriental lilies this year or last. Are others seeing this decline? I know my hand picking could not have decimated the population to extinction! Enjoy the rest of the summer; slow down and watch the insects. Important Proposed Change in Bylaws: Last year at the Annual Meeting, a proposal was floated to add a "Life Member" category for membership, with a total cost of $200 for membership for the entirety of the natural life of the subscribing member. This would necessitate a change in the M.E.S. Bylaws, and will be one of the important items on the agenda for the Annual Meeting in September (see p. 2). One of the interesting parts of my job is seeing various insects that catch people's attention and leads them to seek an answer as to what it is they have found and what it is doing there. The big is certainly on that list. Eastern Dobsonflies (Corydalus cornutus) are quite impressive at 120 mm or so in length, although a person recently thought she had the Giant Asian Dobsonfly that comes in at 210 mm.

    A Study of the Feculae of Orthoptera, Their Specificity, and the Role Which the Insects'mouthparts, Ahmen- Tary Canal, and Food-Habits Play in Their Formation

    A study of the feculae of Orthoptera, their specificity, and the role which the insects'mouthparts, ahmen- tary canal, and food-habits play in their formation BY S. K. GANGWERE (Detroit) 1 (Láms. VII-VIII.) Many physiological studies have been carried out on different as- pects of the feculae ("feces") and their formation in Orthoptera (sens. lat.). Among the more important of these researches are ones by Nenjukov and Parfentjev (1929), Nielsen (1943), and Snipes and Tauber (1937), who described for various species the speed of transit of food through the alimentary canal, i. e., rate of formation of feculae; Chauvin (1946), the periodicity of defecation in four species ; Bro-wn (1937) and Chauvin (1941), the biochemistry of feculae ; Brown (1937), their structure ; and numerous authors, the general physiology of di- gestion and excretion in Orthoptera. Surprisirigly, however, purely descriptive studies on feculae have lagged. Frost (1928; 1959) revie- wed insect "scatology", but included scant material relative to Orthop- tera ; Weiss and Boyd (1950) described and figured the feculae of three species of Orthoptera, and Boldyrev (1928) did the same for a species of katydid ; and Day (1950) described, but did not figure, those of a species of cockroach. Nowhere, apparently, is there a study which elucidates the form and specificity, if any, of fecttlae in the major groups of Orthoptera, nor is there one which discusses satisfactorily the factors which influence their formation. It is in answer to these two questions that the present study was initiated and completed. Contribution No. 63 from the Department of Biology, Wayne State Uni- versity, Detroit 2, Michigan.
