thorax, sutural margins obscurely brown; the legs infuscate, 
tarsi testaceous; the antenne, two basal joints obscurely 
brown, joints 3 to 9 formed somewhat like those here figured 
for D. letabilis, but the appendages are relatively much 
longer; thus the appendages to joints 9 and 10 are four times 
as long as the articulation itself. ' 
At first I hesitated to include this species in the genus 
Drupeus; but the maxillary palpi, slender and _ similarly 
formed tarsi, and the antenne correspond in their general 
structtre almost exactly.

There is a Chinese species of Hubrianax in the British 
Museum labelled in Dr. Horn’s handwriting ‘ Placonycha,” 
and Leconte’s description of the American species evidently 
refers to one belonging to the genus Hubrianax. The claws 
in this genus are slender and simple, moderately dilated at 
the base, with a slender membranous appendage arising from 
the base, which is nearly as long as the claw itself. 1 found 
three species in Japan and two species in Ceylon; and it is 
probable species occur over the greater part of Asia. 
Eubrianaz granicollis, sp.n. (PI. VI. fig. 2.) 
Ovatus, parum convexus, niger, nitidus; thorace antice producto,

This species differs only from £. ramicornis, Kies., in one 
or two particulars. The antennal ramifications are little more 
than half the length, the thorax is densely granulate ante- 
riorly and protrudes over the neck, the tibia, especially the 
acme pair, are stouter and shorter, and the legs wholly 
ack.
