SOME HEMIPTERA HETEROPTERA FROM N. W. BORNEO. 83 
17. Colpura diplochela n. sp. 
Oblong, black, more or less incrusted with fuscous, an oblong 
spot near middle of apical margin of corium and apical margin of 
last three ventral segments (except laterally) ochraceous, mem- 
brane brown, its inner basal area and the basal border darker, apical 
border of connexival segments (above but not beneath), anterior 
orificial tubercle, and trochanters dark luteous or ferruginous, first 
rostral joint pale brownish (the other joints wanting) ; above 
sparsely punctured, more thickly so beneath, puncturation on 
pleime coarser and cinereous; above, and more distinctly beneath, 
sparingly clothed with short hair-like yellowish scales. Head one- 
fourth longer than broad, distance between eyes and apex of an- 
tenniferous tubercles scarcely longer than the longitudinal diameter 
of the eye, gense unarmed, first antennal joint slightly longer 
than head, second less than one-half longer than first (last two 
joints wanting). Prothorax twice as high as head, pronotum 
moderately declivous, one-third broader than long, very feebly 
convex, transversely slightly impressed before middle, lateral mar- 
gins very broadly and slightly sinuate, lateral ruga very distinct 
also from above, anteriorly a little widened, apically produced in 
a strong triangular tooth directed for- 
wards and very slightly outwards, humeral 
angles rounded, not prominent. Meta- 
pleurae foveately impressed near middle 
of lateral margins, their posterior margin 
straight. Abdomen a little broader than 
pronotum and elytra, apical angles of 
fifth segment distinctly prominent, ven- 
ter conspicuously grooved from its base 
to near apex of fifth segment. Femora 
two or three small tubercles bearing a 
Male genital segment of C. 
diplochela: 
unarmed, beneath with 
bristle. Length, $ 14.5 mm. 
Male: genital segment (of. fig.) behind in its apical half 
broadly and slightly impressed, the apical margin laterally pro- 
duced in a strong curved acute horn, median part of the margin 
with two inwardly hooked processes. 
Mt. Penrissen, Sarawak. 
Allied to the Indian C. erebus Dist. (as redescribed by Bred- 
din from a cotype), but with shorter second antennal joint, dif- 
ferently constructed pronotal apical angles, etc. In the structure 
of the male genital segment it is very distinct from all species of 
which this segment has been described. 
18. Colpura variipes Westw. 
Mt. Penrissen, Sarawak. 
With the many Bornean specimens of both sexes before me — 
all taken at the same time and locality — I do not hesitate to unite 
C. armillata Bredd. with variipes Westw. ( annulipes Dali.). It is 
R. A. Soc., No. 83, 1921.
