Excepting 0. vitiosa Base., which is 4.2 millimeters long, this 
is one of the smallest species of Odosyllis and is readily recog- 
nizable by the dark brown scale pattern of the elytra. Black; 
below reddish white, above ashy with brownish shades and 
patches of blackish scales; rostrum reddish, finely seriate-punc- 
tate, isabelline-scaled at base, with a bare dorsal stripe; the two 
elongated basal joints of funicle of equal length, the following as 
long as thick ; head fawn colored, an indistinct median stripe on 
vertex and some scales on inner border of eye paler; thorax 
transverse (3 : 4.1) , sides in basal third feebly rounded, in apical 
part strongly constricted, the latter and some patches on pos- 
terior angles paler cloudy; two approximate basal spots in the 
middle nut-brown scaled, the granules sparse and minute, irreg- 
ularly scattered, and with an anteriorly inserted scale bristle; 
posterior half, except the hind angles and an area on each side 
of disk, free from granules; scutellum convex, ovate, ochra- 
ceous; elytra produced on apex of suture into a short point, at 
base transversely impressed, the intervals in basal half coarsely, 
in apical half much more finely and remotely granulate; a quad- 
rate sutural spot behind scutellum, a short basal stripe on third 
interval, a transverse, postmedian, outwardly dilated band, 
common to the first to third intervals, and produced anteriorly 
in such a manner on first interval that it forms on the right an 
L-shaped (reversed on the left) pattern of dark nut brown, 
limited behind by a large whitish band; below closely whitish 
squamose, the scales of prosternum more or less isabelline- 
colored in the center ; hind femora hardly reaching hind margin 
of fourth sternite and with a feeble trace of a longitudinal 
carina.

dine paulo longiore ; prothorace fortiter, in parte apicali minute, 
vitta indistincta intra marginem lateralem vix granulata; scu- 
tello elytris concolore, his subtiliter striatis, spatiis uniseriatim 
nigro-nitido-granulatis, spatii primi dimidia parte basali gran- 
ulis partim vix diametro eorum inter se distantibus; sutura
