SOME HEMJPTERA HETEROPTERA FROM N. W. BORNEO.

■ed lateral angles. Scutellum with the basal area distinctly ele- 
vated, reaching its middle. Elytra slightly passing apex of abdo- 
men ( $ ), apical margin of corium straight, membrane slightly 
bronzed, here and there a little infuscated. Abdomen with the 
■apical angles of the segments somewhat rectangularly prominent, 
second ventral segment at the base slightly and very obtusely tuber- 
culate, last male ventral segment in the middle one-fourth longer 
than the preceding one, male genital segment arcuately sinuate at 
-apex. Length, $ 12.5 mm. 
Fourth mile. Rock Road, near Ivuching, Sarawak. 
Apparently coming nearest to T. ferruginescens Bredd., but 
much larger, much more sparingly punctured beneath, with a 
•distinct callus at the scutellar basal angles and quite different 
colour- markings of the pronotum and connexivum. 
3. Aeschrocoris saucius n. sp. 
Black, with the apical part of the pronotal median carina 
and many irregular spots in all parts of the body, excepting head, 
sanguineous or ferruginous, coarsely and rather densely punctured, 
head more thickly, and scutellum less thickly so ; antennas fuscous, 
articulations between the first four joints narrowly whitish; 
rostrum piceous ; legs black, a broad median annulation to femora 
and often also a narrower annulation just before middle of tibiae 
sanguineous. Head two-thirds longer than broad, laterally broadly 
but not deeply sinuate, vertex with two parallel longitudinal keels 
near each other, elypeus narrow but percurrent, carinately elevated 
in its basal half, juga a little longer than elypeus but not meeting 
in front of it, obliquely truncate or sinuate at apex, first two an- 
tennal joints of equal length, the following joints successively 
increasing in length, rostrum reaching apical margin of second 
ventral segment. Pronotum with a rather strong percurrent longi- 
tudinal keel in the middle, the reddish spots of the anterior part 
of the disk c-allosely elevated, the apical angles produced in a short 
porrect acute tooth, the humeral processes shaped as in A. obscurus 
Dali., directed outwards, forwards and more or less upwards, the 
apical teeth horizontal. Scutellum somewhat elevated at the base 
and with a large and deep fovea at the basal angles, the apex raised 
in a stout conical semi-erect tubercle as high as the transverse dia- 
meter of the pronotal humeral processes. Elytra slightly passing 
apex of abdomen, corium conspicuously shorter than scutellum, its 
apical angle rounded, membrane somewhat longer than corium, 
fuscous until a more or less distinct dark testaceous basal spot, the 
veins connected near apex with the adjacent veins bv a more or 
less distinct transverse vein, but not otherwise reticulated. Abdo- 
men at the apical angles of the segments with a small tubercle, 
male genital segment sinuate at apex. Length, $ 7 mm., hum. 
width 8 mm. ; 2 8 mm., hum. width 8.5 mm. 
Fourth mile, Rock Road, near Kuching, Sarawak; Sumatra 
(my collection).
