Species of Alcides from the Oriental Region, 401 | 
shaped like a horse-shoe; moreover, the contiguous stripes 
on intervals 8 and 9, instead of being much shorter than 
that on 7, are nearly or quite as long; and there is no trace 
of the median stripe on the pronotum. ‘The sides of the 
prothorax are not parallel in the basal half, but distinctly 
convergent in front. 
Length 9°5-10°5 mm., breadth 3°75-4 mm.

Described from four specimens. 
Alcides jugalis, sp. n. (PI. VII. fig. 5.) 
3 @. Form subecylindrical; integument black, with pale 
markings formed of small, short, whitish, plumose scales 
dusted with ochreous powdering ; the pronotum with three 
stripes, the median one much narrower than the laterals, and 
all reaching the apex; the elytra with a broad sutural 
stripe on intervals 1 and 2 from the base almost to the 
middle ; a uarrow, shorter, and rather oblique stripe start- 
ing at the base on interval 6 and ending on interval 4; 
a broad, complete, common, transverse band behind the 
middle, which widens and curves forwards at the sides, being 
continued to the base as a narrow stripe along interval 10; 
and a subtriangular apical patch covering all the declivity 
except interval 11 ; the lower surface fairly densely covered 
with plumose scales and ochreous powdering, which are 
thinner down the middle of the metasternum and abdomen. 
Head unusually broad, longitudinally rugulose, and with- 
out any median fovea. Rostrum stout, subcylindrical, 
almost straight, slightly narrowing from the base to the 
middle, and feebly widening again at the apex, of about equal 
length in the two sexes, coarsely punctate and longitudinally 
striolate at the base, and with a broad deep furrow on each 
side between the eye and antenna; the punctures strong and 
close throughout in the ¢, almost as strong on the basal 
half in the ¢, but much finer apically. Antenne inserted 
beyond the middle in both sexes, the scape a little shorter 
than the funicle, of which joint 1 is longer than 2 and 8, 
3 to 6 are bead-like and transverse, and 7 is much shorter 
than the club. Prothorax a little shorter than its basal 
width, subconical, gradually narrowed from base to apex, 
with the sides only slightly rounded and the subapical con- 
striction feeble; the dorsal apical margin rounded, the 
longitudinal outline almost flat, but the whole prothorax 
tilted upwards in front; the dorsum set throughout with 
small separated granules, those on the discal area each
