SOME HEMIPTERA HETEROPTERA FROM N. W. BORNEO. 85 
Mt. Fenrissen, Sarawak. 
Allied to /S', stenocephwla Bredd., 'from which it differs by 
smaller size and in having the head a little shorter, the pronotum 
less convex with the lateral ruga distinctly visible from above in 
its anterior half, the femora unarmed, the antennae and tibiae much 
more distinctly palely annulated, and the pale spots at the apical 
angles of the abdominal segments scarcely distinguishable. It is 
very similar in. colour to Colpura variipes Westw., but is at once 
distinguished by the generic characters. 
Stenocolpura was originally described by Breddin (Revue 
d’Ent. 1900, p. 203) as a subgenus of Colpura, but in agree- 
ment with his later suggestion (Ann. Soc. Ent. Belg. 1906, p. 55) 
T consider it generically distinct. It differs from Colpura prin- 
cipally in the structure of the head and the sexual characters of 
both sexes. The head is longer and narrower than in Colpura, the 
eyes are more removed from the base, the lateral margins behind 
the eyes are only slightly rounded without the conspicuous posto- 
cular callus so characteristic of Colpura, the apical margin of the 
male genital segment is evenly rounded, not at all sinuated, the 
sixth female ventral segment is not cleft in the middle, as in 
Colpura, but posteriori}' triangularly incised with the basal plica 
reaching the incisure, and the latero-apical lobes of the female 
genital segment are much broader than long. To this can be added 
that the prothorax seen in profile is higher compared with the 
head, the pronotum strongly sloping, the rostrum very long, and 
the venter deeply grooved almost down its whole length. 
The Coreidae of the division Hygiaria are apparently more 
frequent, both as to species and specimens, in mountain regions 
than in the lowlands. In addition to the five species recorded above 
there is in the Sarawak Museum a specimen (from Trusan) of the 
Bornean Colpura pacalis Bredd. 
21. Dasynus shelfordi n. sp. 
Brownish-ochraceous, the narrow costal margin of corium and 
the levigate veins and apical margin of corium and clavus, and a 
percurrent longitudinal band on each side of venter between its 
middle and lateral margins of a lighter ochraeeous colour, a narrow 
percurrent vitta immediately within pronotal lateral margins fus- 
cous, membrane brown with its inner basal area olivaceous-black, 
the two pale ventral vittae at their exterior margin with a series of 
short fuscous streaks, one in each segment, the spiracles pallid; 
antennae fuscous, first joint brownish ochraeeous, apex of the three 
first joints fuscous-black, fourth joint black with a broad subbasal 
pale ochraeeous annulation ; rostrum and legs brownish ochraeeous ; 
above, excluding head and apical pronotal area, rather thickly 
punctured with fuscous-black, pleura 1 coarsely and thickly punctate 
with pale fuscous. Head slightly broader than long, very dis- 
tinctly produced beyond antenniferous tubercles, above almost im- 
punctate, beneath obscurely eoneolorously punctured, bucculae un-
