latter notched on each side; antenne pitchy, second 
joint of the funicle half as long again as the first, the 
rest rounded and mostly equal in length and breadth ; 
club short; eyes lateral, ovate; prothorax markedly 
longer than broad, moderately contracted at the apex, 
the sides slightly rounded to the middle, coarsely pitted 
above, the intervals granuliform, a narrow elevated line 
nearly throughout; scutellum cordate; elytra broader 
than the prothorax, the sides nearly parallel, flat along 
the sutural region, declivous at the apex, sloping towards 
the sides and abruptly bent down at the shoulders, the 
preapical callus prominent; body beneath and legs with 
numerous silaceous scales. 
PLETHES. 
Characteres ut in Hilipodo sed femora mutica vel sub- 
mutica. 
There is no character so constant in Hilipus as the 
strongly-marked femoral tooth, so that, in so large a 
genus, it is a matter of convenience to exclude all species 
that do not possess it. There are other characters in 
common, but which, having regard to Hilipus, can hardly 
be considered of generic importance. 
Plethes albolineatus. (Pl. IL., fig. 6.) 
P. pyriformis, niger, subnitidus, elytris lineis albo- 
squamosis ornatis, apice rotundatis. Long. 8 lin. 
Hab. Colombia. 
Pear-shaped, black, somewhat glossy, the elytra with 
narrow lines of pure white scales; rostrum of moderate 
length, slightly curved, gradually broader from the base 
to the apex, smooth, finely punctured, scrobes running 
beneath ; antenne black ; two basal joints of the funicle 
equal, the rest gradually shorter and broader, the last as 
broad as the club (of which it looks as if it formed a 
part); eyes lateral; prothorax small, subcylindrical, 
transverse, abruptly constricted anteriorly; scutellum 
subscutiform ; elytra shortly ovate, broadest behind the 
middle, punctate-striate, the alternate interstices raised, 
smooth; the second, fourth, and sixth (the two latter 
joined posteriorly) filled with white scales, the apex 
rounded; body beneath and legs smooth, glossy; the 
abdominal segments finely punctured.
