NO. 2150. SOME NLJW HETEROI'TEROUS HEMIPTERA—BERGROTH. 225 



joint constricted near base, somewhat dilated toward apex. Pro- 

 notum sparsely punctured with fuscous, apical margin neither 

 smooth nor elevated, lateral margins narrowly reflexed, very slightly 

 sinuate or almost straight, lateral angles very narrowly rounded. 

 Scutellum very distinctly longer than broad, punctured the same 

 as the pronotum. Breast impunctate, except a few colorless punc- 

 tures on the posterior part of the propleurae. Hemelytra consider- 

 ably passing apex of abdomen, corium more than twice the length of 

 scutellum, costal margin reflexed from base to beyond middle, apical 

 angle very acute, apical margin slightly bisinuate, exocorium rather 

 sparingly punctured with fuscous, mesocorium sparsely and ex- 

 tremely finely concolorously punctulate, but with a series of much 

 larger close-set pale fuscous punctures along the interior margin, en- 

 docorium with a similar row of punctures along the exterior and in- 

 terior margins; membrane narrowly rounded at apex, transparent, 

 tinged with fuscous, more so at apex. Wings iridescent, hyaline, 

 rather broadly infuscated at apex. Abdomen impunctate, apical 

 angles of the segments not at all prominent. Legs greenish tes- 

 taceous 



Length (without membrane). — Male 10.8 mm., female 12^ mm. 



Males. — First genital segment subtriangular, transversely strongly 

 convex, apical margin a little sinuate in the middle ; second genital 

 segment beneath in the middle with a rather long straight process 

 directed backward and a little upward, constricted near base and 

 somewhat dilated toward the truncate end, at the upper basal angles 

 of the segment with a tubercle and immediately behind this with a 

 spine-like process directed obliquely backward, upward, and a little 

 outward, the interior margin of this process, the apical margin of 

 the segment, and the margins of the median process fringed with 

 pale hairs; the interior appendages bifid at tip. 



Female. — Dorsal genital segment a little shorter and narrower 

 than sixth dorsal segment, apical margin slightly sinuate, the lateral 

 parts visible from beneath in the form of a curved triangular lobe; 

 ventral genital lobes triangular, much broader than long, the pos- 

 terior ones apically produced in a triangular lobe visible also from 

 above, between these lobes two smaller triangular lobules protruding 

 from the interior. 



Type.—C2it. No. 20146, U.S.N.M., China (Foo-chow, H. R. Cald- 

 well). 



Very distinct from all previously described species. It has a pe- 

 culiar facies, different from that of the other species I have seen, 

 and reminding one of a green blattid. After death the green color 

 of the head, and partly also of the pronotum and scutellum, more or 

 less fades into testaceous. The male genital segment is not unlike
