Kelisia pectinata Beamer Additional specimens of this species have been taken in Tinley Park and Paxton, III, July, 1946. Kelisia retrorsa Beamer

The range of this species has been increased by material from the follow ing localities: Canaan, N. H.; Colchester, Conn.; Storrs, Conn.; and Ding mans were Ferry, Pa. All taken in August, 1946.

1.Kelisia torquata n. sp.

Brachypterous form: curvata on Resembling Kelisia Beamer but longitudinal dark stripe elytra near a very light, process middle of aedeagus with many divisions instead of a single process and lyre-shaped anal segment processes without median basal tooth in caudal view. Length S 3 mm., 2 3.2 mm. to more Structure: Elytra widest just before base, tapering pointed apices, so on mesal margins, extending about one-seventh their length beyond tip of to abdomen. Hind wings reduced tiny pads. a Color: General color stramineous with very light amber colored stripe to from hind margin of eye tip of elytra where it is usually darker, stripe not more area usually covering than one-third of elytra; body usually without definite dark markings. more or Genitalia: Pygofer of male in lateral view less triangular, posterior with angle broadly rounded, basal angles somewhat sharper; anal segment as as a posterior margins truncate, less than half long inner margin with basal at a pair of processes widest base, lyre-shaped in caudal view without median a tooth; aedeagus long and broader than normal for the genus with basal a ventral process which ends just before middle of shaft in number of finger like processes, the number variable; apex of shaft more or less twisted with a on not sharp tooth either side before tip bilaterally symmetrical.
