at basal third ; length, 2.2 mm. 440. clitoris. 



aa. Costal area without premedian dark cross-bar; joint 3 of antenna? 



as long as pronotum, 1 three or more times as long as 2. 



b. Nervures of costal area of elytra white; basal third of costal area 



with a single row of large rectangular cells ; elytra widest near 



apex; length, 2.7 mm. 441. oblonga. 



bb. Nervures of costal area brown, or fuscous; basal half or more of 



costal area with an outer row of large cells and an inner row of 



smaller ones; elytra as wide across discoidal area as at apex; 



length, 3 mm. 442. heidemanni. 



440 (661). Gelchossa clitoris (Heidemann), 1911, 180. 



Elongate-oblong, constricted at humeri and again near middle of 

 elytra. Head, under surface, disk of pronotum, subcostal area and a 



broad premedian bar on costal area of 

 elytra, black; reflexed margins of para- 

 nota and basal fourth of costal margin of 

 elytra white; carina? and triangular tip 

 of pronotum, nervures of preapical third 

 or more of costal area of elytra, legs and 

 third antennal straw-yellow; discoidal 

 area and apical fourth of elytra fuscous, 

 the latter with two or three large hyaline 

 cells; first and second antennals brown; 

 fourth fuscous. Head with a stout median 

 curved spine and two smaller ones below. 

 Hood, viewed from the side, compressed, 

 carinate above and with two vertical rows 

 of cells in front of several larger ones. 

 Median carina of pronotum arched and 

 in front almost as high as hood. Paranota 

 narrow, reflexed and with two rows of 

 cells. Costal area with two rows of cells. 

 Length, 2.1—2.3 mm. (Fig. 107). 



Crawford Co., Ind., Aug. 1 — 30; common locally on bush 

 clover, Lespedesa, butterfly pea, Clitoria mariana L., and other 

 legumes, along high wooded slopes. The known range extends 

 from Massachusetts west to southern Michigan and Tennessee 

 and south to South Carolina and Arkansas. Van Duzee (1917) 

 makes clitoria- a synonym of L. constricta Champ. China com- 

 pared Indiana specimens with the type of constricta and found 

 the latter to be broader, head wider, its apex pale; hood glo-
