NOTES ON ACADICA AND OTHER UNUSUAL HAIRSTREAK RECORDS (LYCJENIDJE) IN SOUTHEASTERN PENNSYLVANIA

During the summer of 1961 I had the unexpected pleasure of discover­ ing a colony of Satyrium acadica (Edwards) in Cheltenham Township, just north of Philadelphia, Pa. Shortly afterwards information was communicated to me of a similar discovery along the Wissahickon Creek, about eight miles to the southwest of the aforementioned locality. S. acadica is a northern species and its occurrence this far south as a breeding resident is rather exceptional. Mr. GEORGE EHLE mentions that he had not heard of it south of the Pocono Mountains in Pennsylvania. This may be a new southern record for acadica as a breeding resident. Records are from July 4-11. The species is not numerous. I took only one but saw several (5 or 6) more. My specimen is a very large female, expanding 33.4 mm. A male caught along the Wissahickon Creek measured 27.5 mm. These dates are somewhat after the common S. falacer and edwardsii hit their peak. Both localities are damp and the seems to be associated with the . It visits blossoms of Milkweed (Asclepias syriaca) freely but does not seem to wander far from the , and is quite wary. Several good Hairstreak records for Philadelphia are based on strays of southern species. On Sept. 10, 1960, I had the fantastic luck to catch one each of Eupsyche m-album (Boisduval & LeConte) and Calycopis cecrops within one hour's time. The cecrops seemed fresh but the m-album was very worn. Another good species, which is common in a few spots mostly west of the city, is Satyrium titus.

ADDITIONAL RECORDS OF SATYRIUM BEHRII (LYClENIDJE) FROM OREGON

The remark in Ehrlich & Ehrlich, How to know the (p.192; 1961), by CLENCH, that Satyrium behl'ii was not recorded from several expected states, has resulted in the publication of records from Nevada by PHILIP (J ourn. liepid. soc. 15: 56; 1961) and from Oregon by CLENCH (ibid. 16: 44; 1962). Two additional Oregon specimens are in the collection of TILDEN. One is labelled incompletely, "Metolius River, Ore., VII.3.40", without notation
