the former strongly, the latter moderately incrassate, the second and 
two following nearly equal, moderately slender, the seventh equal in 
length to the sixth, obconic, the next three submoniliform, the eleventh 
as long as the seventh, ovate; epistome wedge-shaped; eyes entire. 
Thorax broader than long, subcylindrical above, side margin distinct ; 
surface of disk covered with curved scales. Elytra punctate-striate, 
surface covered with subdepressed scales, arranged, as in Apolepis, in 
parallel rows. Legs moderately robust ; hinder thighs armed beneath 
with a small tooth; basal joint of tars? scarcely longer than the second ; 
claws bifid. Prosternum subelongate, separated from the episternum by 
a broad sutural groove, its front edge somewhat produced and conceal- 
ing the mouth. Mesosternum subquadrate, its apex slightly dilated, 
trilobate. 
Type, Lepina inconspicua, Baly. Pulo Penang. 
This genus is also found in Sumatra. The form of the scales at 
once divides Lepina from Aulacolepis; in habit it agrees closely 
with Apolepis, but the sutural groove between the prosternum and 
the episternum separates it from that genus. 
Lepina inconspicua, Baly. 
L. oblong, subcylindrical, rufo-piceous, subnitidous, covered with suberect, 
narrow, curved scales; thorax (its anterior border excepted), base of 
thighs, knees, and outer half of antenne dark nigro-piceous.—Long 
13 lin. 
Hab. Pulo Penang. Collected by Mr. Bowring. 
This insect bears a strong resemblance to Apolepis aspera; m 
addition, however, to the structural characters, the scales covering 
its surface are much narrower, less rigid, and less erect, those on the 
thorax being almost adpressed. Thorax coarsely punctured. Elytra’ 
punctate-striate near the suture, puncturing confused on the disk, 
scales arranged as in Apolepis. 
Genus AULACOLEPIS. 
Body oblong, subcylindrical, clothed with large, broad, rigid, adpressed or 
suberect curved scales, surface of the scales longitudinally concave. Head 
short, perpendicular, more deeply immersed in the thorax than in the 
other genera of the group ; antenne scarcely longer than the head and 
thorax, their basal half slender, their outer portion moderately incras- 
sate, basal joint thickened, second moderately thickened, two-thirds the 
length of the first, third and three following joints each about equal 
in length to the first, each slightly decreasing in length, also slightly 
thickened at their apex, four following joints moderately thickened, 
nearly equal, submoniliform, the eleventh rather longer, ovate; eyes 
entire; mentum angulate-emarginate; last joint of maxillary palpi
