380 FAMILY XI. — LYGJEWJE. 



notum not sufficiently constricted or impressed to form two 

 distinct lobes, its hind margin straight; elytra punctate, the 

 punctures in evident rows; front femora much swollen and 

 armed beneath with several small unequal teeth or spines; 

 corium not wider than abdomen ; membrane with all the veins 

 running from the base, the two inner ones not connected. 

 Other characters as in subfamily key. Three genera are in- 

 cluded in the subfamily, two of which are represented in the 

 eastern states. 



KEY TO EASTERN' GENERA OF PACHYGRONTHIN.E. 



a. Head strongly declivent, almost vertical; antennae with first joint 

 shortest, not reaching tip of tylus; scutellum subequilateral, not 

 calloused each side at base; clavus very narrow, its commissure 

 scarcely evident. I. Phlegyas, p 380. 



aa. Head but feebly declivent; first antennal longest, much surpassing 

 tip of tylus; scutellum slightly longer than wide and with a pale 

 calloused spot each side of base; clavus wider, more so near apex, 

 its commissure distinct. II. CEdancala, p. 382. 



I. Phlegyas Stal, 1865, II, 145. 



Small oblong, robust species having the antennae but slightly 

 longer than pronotum, second joint longest, nearly three times 

 the length of first, third and fourth subequal ; cheeks not cari- 

 nate; front of head flattened; pronotum subtrapezoidal, but 

 slightly narrowed in front; elytra usually narrower than ab- 

 domen ; hind margin of corium feebly sinuate toward apex of 

 clavus, its outer apical angle rounded; connexivum usually 

 widely exposed. Female with fourth ventral very narrow at 

 middle, fifth with sides very long, narrowed and meeting be- 

 neath middle of fourth. Two species occur in the eastern 

 states.
