SUBFAMILY III. — BLISSIN^E. 363 



breviceps Stal, a synonym, from five other stations in Florida. 

 The types of Fabricius were from "Insulae America? meridio- 

 nalis," while those of Stal's breviceps were from Carolina and 

 Texas. It ranges from New Jersey southward in the coastwise 

 states to Mexico and Porto Rico, but is known from the eastern 

 inland states only from Indiana. Recorded also by Pennington 

 from Argentina and by Uhler as breviceps from Colorado, Utah 

 and California. In the form of body, and especially the prono- 

 tum, virescens is more closely allied to luridus than to any of our 

 other species. The Cymodema exiguum Horv. (1908, 559) is also a 

 synonym of virescens. 



Subfamily III. BUSSING Stal, 1862a, 210. 



Small elongate or oval species having the head broader across 

 the eyes than long, but narrower than hind margin of prono- 

 tum ; pronotum usually not sufficiently constricted or impressed 

 to form two lobes, punctured, without carina; elytra often di- 

 morphic in length, impunctate; clavus not narrowing behind, 

 the commissure at least half the length of scutellum ; front 

 femora thickened, unarmed beneath. Females with ventrals 

 5 — 6 narrowed, overlapping and converging forward. Other 

 characters as in subfamily key. Two genera are recognized, 

 both represented in the eastern states. 



KEY TO EASTERN GENERA OF BLISSIN.E. 



a. Body elongate, abdomen over twice tbe length of head and thorax 

 united; beak not surpassing middle coxae; scutellum equilateral; 

 hind margin of corium straight. I. Ischnodemus, p. 363. 



act. Body short, oblong-oval, abdomen less than twice as long as head 

 and thorax united; beak surpassing middle coxa?; scutellum wider 

 at base than long; hind margin of corium sinuate before apex of 

 clavus. II. Blissus, p. 369. 



I. Ischnodemus Fieber, 1836, 337. 



Slender-bodied Lygseids having the antennas slightly longer 

 than head and pronotum united, first joint, short, stout, pass- 

 ing apex of head, fourth fusiform ; pronotum usually with a 

 more or less evident transverse impression ; abdomen concave 

 above, enclosing the elytra, the latter usually reaching its apex, 

 macropterous form, often scarcely longer than pronotum, bra- 

 chypterous form ; front coxal cavities closed behind along the 

 hind margin of prosternum. The genus is a large one, Stal 

 (1874, 130) recognizing 21 species, mostly from the tropical 

 regions. A number have been since described and seven species
