SUBFAMILY I. — LYG^EIN^. 355 



291 (469). Nysius grcenlandicus (Zetterstedt) , 1838a, 262. 



Form and size of ericse to which it is very closely allied. Differs in 

 having the general color darker, the clavus and corium in great part 

 brown or fuscous, the apical margin of corium wholly so. Head longer 

 and more pointed. Pronotum wider and less narrowed in front, its punc- 

 tures fewer, much coarser, more unevenly placed. Length, 3.2 — 3.5 mm. 



Nain, Labrador (Barber). "Greenland, Labrador, Hudson's 

 Bay Terr., Alaska." (Van D., 1917). 



V. Belonochilus Uhler, 1871, 104. 



Head very long, subequal in length to pronotum ; tylus dis- 

 tinctly surpassing first antennal ; eyes not in contact with front 

 margin of pronotum ; joints 3 — 4 of antennae subequal in length, 

 second slightly longer, fourth stouter, fusiform ; beak reach- 

 ing or surpassing fifth ventral ; costal margin of corium 

 straight, parallel ; connexivum narrowly exposed ; osteolar duct 

 not auriculate at apex. Female with ventrals 3 — 6 as in other 

 Orsillini. Two species are known, both occurring in the eastern 

 states. 



KEY TO SPECIES OF BELONOCHILUS. 



a. Front femora armed beneath at apical fourth with a small spine; 



pronotum with only a trace of a pale median line; male genital 



with a small tubercle. 292. numenius. 



act. Front femora unarmed beneath; pronotum with entire pale median 



line; male genital foveate. 293. koreshanus. 



292 (473). Belonochilus numenius (Say), 1832, 15; I, 331. 



Elongate-oblong. Dull yellow; median line of head, smooth areas on 

 hind lobe of pronotum, median carina of scutellum, costal margin of 

 corium, coxa?, tibia? and abdomen, in great part, pale yellow; apex of 

 corium and middle of margin of each connexival, reddish; membrane 

 with a vague reddish stripe at middle; femora dotted with brown; knobs 

 over basal angles of pronotum, last joint of beak and sometimes a stripe 

 on head and spot on middle of abdomen, blackish. Pronotum punctate, 

 the transverse impression deep; front lobe half the length of hind one, 

 the latter higher, convex. Scutellum with transverse keel narrow, angu- 

 late. Beak somewhat variable in length, often reaching genital plate. 

 Length, 5.3 — 6 mm. 



Marion, Knox and Posey counties, Ind., scarce ; April 23 — 

 Oct. 12. The April specimen was taken beneath a fungus-cov- 

 ered log, so that it probably hibernates as adult ; the others by 

 sweeping shrubs along streams. Ranges from Massachusetts 

 and New York west to Arizona and California. Not taken in 

 the east south of Maryland. Van Duzee took it near Buffalo, N.
