430 FAMILY XI. — LYGMIDJE. 



/. Pronotum nearly twice as wide as long, its hind lobe sparsely 

 punctate; membrane reaching apex of abdomen. 



V. Valtissius, p. 434. 

 //. Pronotum distinctly less than twice as wide as long, its hind 

 lobe impunctate; membrane abbreviated; dorsal surface very 

 shining. VI. Xestocoris, p. 435. 



ee. Side margins of pronotum narrowly expanded, subparallel, usually 

 pale and bordered within by an impressed line; width of head 

 across eyes much narrower than across front angles of prono- 

 tum. VII. Cryphula, p. 436. 



I. Drymus Fieber, 1861, 46, 178. 



Species of small or medium size and having the head not 

 inserted in thorax to eyes ; pronotum with side margins rounded 

 in front of middle, their edges but slightly expanded, more so 

 opposite the constriction between the lobes, front lobe without 

 definite collar; scutellum flat, rather thickly punctate, with a 

 faint carina near apex ; elytra entire, reaching tip of abdomen ; 

 hind tibiae without rigid bristles ; third ventral suture strongly 

 curved, not reaching side margin ; front femora armed beneath 

 with a spine and several minute teeth. Two species are known, 

 both occurring in the eastern states. 



KEY TO SPECIES OF DRYMUS. 



a. Pronotum with side margins narrowly pale, broadly rounded behind 

 front angles ; front lobe of pronotum darker and more finely punc- 

 tate than hind one. 382. UNUS. 

 aa. Pronotum with margins and entire disk dark brown, the margins 

 more strongly rounded; both lobes evenly, densely and rather 

 coarsely punctate. 383. crassus. 



382 (598). Drymus unus (Say), 1832, 16; I, 333. 



Elongate-oval. Head, front lobe of pronotum, scutellum and sterna 

 dark brown; hind lobe of pronotum and elytra brownish-yellow punctate 

 with fuscous, the corium often with vague darker blotches; membrane 

 brown, the veins paler; antenna? reddish-brown, the third joint and base 

 of fourth darker; ventral surface of abdomen and femora reddish-brown, 

 tibiae and tarsi paler. Head and front lobe of pronotum finely not densely 

 punctate. Costal area of corium narrowly expanded. Length, 4.2 — 5 mm. 



Lake, Porter, Cass and Marion counties, Ind., June 26 — Oct. 

 11. Apparently a scarce species throughout the State, occurring 

 beneath logs, stones, etc., on wooded slopes, usually near 

 streams. Ranges from New England west to Colorado and 

 southwest to North Carolina and Texas. Barber says that in 

 the eastern states it is "commonly found by sifting dead leaves 

 at the base of alders."
