870 COLEOPTERA 



On comparing this species with the male of No. 903 it will be 

 seen that the antennae are much shorter, and the club decidedly 

 rounder ; the rostrum is about one-third shorter and broader ; the 

 head is much longer, broader, and destitute of constriction, so that 

 there is no distinct neck ; the thorax is so much dilated laterally 

 near the base as to be broader than any part of the hind-body ; the 

 posterior margin of the elytra, though not projecting beyond the 

 general outline, is much more distinct ; the hind-body, therefore, 

 seems less narrowed apically.

Eucossonus. 



Nov. gen. 



Body moderately elongate, sub-depressed, setigerous. Rostrum 

 stout, shorter than thorax, somewhat arched, widened in front. 

 Scrobes deep, expanded towards, and attaining, the eyes. Antenna 

 elongate, inserted before the middle ; scape flexuous, incrassated 

 apically, reaching backwards beyond the eyes ; funiculus as long as 

 scape, 5-articulate, two basal joints of nearly equal length, narrow at 

 base, joints 3-5 decrease in length ; club oblong-oval, articulate. 

 Eyes convex, distinctly facetted, distant from thorax. Head much 

 narrowed towards the eyes, its back part or neck smooth. Prothorax 

 longer than broad, well rounded behind the middle, narrowed and 

 considerably constricted anteriorly so that the apex seems much 

 swollen; disc broadly canaliculate. Scutellum moderate. Elytra 

 elongate, not twice the length of and but little broader than the 

 widest part of thorax, parallel, base bisinuate. Legs rather long ; 

 femora simple ; tibia nearly straight, obviously uncinate ; tarsi stout, 

 second basal joint moderate, third broad, its lobes strongly developed, 

 fourth equalling the preceding three in length ; claws simple. Meta- 

 sternum moderately elongate ; abdomen as long as it, its second seg- 

 ment shorter than first, the latter broadly impressed behind. 

 Coxa distant. 



Allied to Sericotrogus, differing from it in the unimpressed pro- 

 sternum, more widely separated and more deeply-embedded coxae, 

 the anterior particularly, and in the structure of the antennae 

 and tarsi, &c. 



1550. E. COmptUS, n.s. Sub-depressed, moderately elongate, 

 ferrugineous, sub-opaque, antennae and tarsi red, snout dark-red ; 

 clothed with yellow scale-like hairs. 



Bostrum shorter than thorax, the portion before the antennal 

 insertion broader than the back part, apex nearly nude, but with 

 slender hairs on the side, much finer than those behind, moderately 

 coarsely but not deeply punctate. Neck nearly smooth. Prothorax 

 nearly twice as long as broad, base slightly bi-sinuate, sides well 

 rounded, considerable narrowed towards the swollen apex ; dorsum 

 broadly canaliculate or impressed, with coarse shallow punctures. 

 Elytra broader than base of thorax but hardly wider than its middle
