888 FAMILY XXIX. — MIRID.E. 



983 (1056). EURYCHILOPTKRELLA LURIDULA Reuter, 1909, 60. 



Dull grayish- or greenish-yellow, very thickly clothed with suberect 

 yellowish hairs; front of head, calli and four oblong-oval spots on basal 

 half of pronotum, scutellum in great part, apical half or more of clavus, 

 inner apical third of corium and cuneus in great part, fuscous-black; 

 embolium and median line of scutellum pale dull yellow; membrane 

 dusky translucent, its veins darker; under surface blackish-brown, shin- 

 ing, gula and prosternum paler; legs greenish-yellow, tinged with fus- 

 cous. Beak brown, reaching first ventral. Antenna? half the length of 

 body, thickly pilose, joints 1 and 2 greenish-yellow, 1 about half as long 

 as width of vertex; 2 darker and visibly thickened toward apex, almost 

 four times as long as 1; 3 and 4 fuscous-brown, united two-thirds the 

 length of 2. Head as in c of key, the tylus and cheeks convex, promi- 

 nent. Pronotum two and one-half times as wide at base as apex, disk 

 behind calli convex, thickly, evenly and rather coarsely punctate. Scu- 

 tellum finely transversely rugose. Elytra, except membrane, very finely, 

 unevenly and shallowly punctate, each puncture bearing an inclined yel- 

 lowish hair. Length, 4.2 — 4.5 mm. 



Chicago, 111., Sept. 12; taken from elm (Gerhard). Recorded 

 only from New York and District of Columbia, where it is said 

 to occur on yellow-wood, Cladrastis hi tea (Michx.) ; also on apple 

 trees and to be evidently predaceous. 



IV. Camptobrochis 1 "' Fieber, 1858, 304. 



Small oblong-oval, subconvex, shining species having the 

 upper surface glabrous ; eyes almost contiguous with pronotum ; 

 vertex carinate at base ; scutellum punctate ; tarsal claws 

 deeply cleft near base. Male with "left clasper tapering gradu- 

 ally to a point, therefore without a barb or hook at tip as in 

 the species of Derceocoris." The adults hibernate and are prob- 

 ably predaceous. Five species are known from the eastern 

 states. 



KEY TO EASTERN SPECIES OF CAMPTOBROCHIS. 



a. Upper surface not red and black. 

 />. Cuneus infuscated or with blackish; membrane marked with fus- 

 cous. 

 c Membrane nearly clear, but with a small round submarginal fus- 

 cous spot each side on apical half; host plant, bur oak. 



984. NEBUI.OSUS. 



cc. Membrane with apical half infuscated, without distinct spots, but 

 paler near tip of cuneus; disk of pronotum often blackish be- 

 hind calli, the median line pale; femora piceous, apical half with 

 one or two pale rings; host plants, white and red pines. 



985. NUBILUS. 



aoKnighl icii'ii made this group a subgenus of Derceocoris. The characters used 



by him in separating it as a subgenus air mainly those used in my generic key and 

 are more distinctive titan those separating many other genera of NUrid;?. I there 

 fore restore tin- old generic name.
