1226 COLEOPTERA 



longitudinal space ; mandibles and palpi prominent. Antenna im- 

 planted near the apex, bearing black hairs ; scape slender, gradually 

 thickened, attaining back part of eye ; basal joint of funiculus 

 longest, second more slender but as long as third and fourth ; joints 

 3-7 decrease in length ; club triarticulate, oblong, opaque with 

 dense pubescence. Head narrowed towards the eyes, closely and 

 coarsely punctate ; vertex slightly concave ; eyes distant from tho- 

 rax, convex, very prominent, distinctly facetted. Protliorax much 

 constricted in front, its sides rounded ; its sculpture like that of the 

 head. Scutellum oblong. Elytra suboblong, not broader at the 

 shoulders than elsewhere ; sub-striate-punctate ; interstices broad 

 and plane, bearing close granulose sculpture, each granule appear- 

 ing to have a puncture from which the pubescence proceeds, the 

 sculpture becomes finer behind. Pygidium prominent, triangular, 

 blackish, coarsely sculptured. Femora stout, anterior medially in- 

 flated, intermediate thicker, with a minute denticle underneath, 

 appearing widely notched at the extremity, posterior compressed, 

 strongly angulated and dentate below ; tibia nearly straight ; tarsi 

 elongate, third articulation cleft to its base, its lobes narrow, so 

 that the minute, true fourth joint can be detected, apical joint as 

 long as the first and second taken together ; claws thickened at 

 base. 



This is the finest species yet brought to light. It is rather long- 

 bodied, with an unusually protuberant pygidium, more prominent, 

 and more rounded, eyes than in the more typical forms, &c. My 

 experience of the Eugnomii does not warrant the institution of a 

 new genus for the reception of this and the following species, all of 

 which exhibit numerous little differences, but these are differences 

 of degree only, and cannot be deemed to be of sufficient importance 

 to separate them generically from such} species as E. fervidus and 

 E. picipennis. 



Length (rost. excl.), 3A; breadth, 1-| lines. 



I am indebted to T. R Cheeseman, Esq., F.L.S., and J. Adams, 

 Esq., B.A., for the only specimen I have seen. They brought it 

 from Mount Arthur. 



2160. E. SBneSCens, n.s. Elongate; thorax and elytra of a 

 dark-violet colour, the latter with a brassy hue, legs and antennae 

 blackish ; tarsi and club fuscous ; clothed with fine yellowish-grey 

 hairs, with numerous short, upright ones of the same colour on the 

 wing-cases. 



Rostrum coarsely and closely punctate, more finely in front, 

 where it is dilated and obsoletely carinate. Thorax constricted at 

 the apex, rounded laterally, convex, coarsely and closely punctured. 

 Scutellum oblong. Elytra suboblong, narrowed posteriorly, almost 

 striate - punctate ; interstices broad and plane, appearing densely 

 rugose, the sculpture granular, with a puncture in each granule ; 

 the sculpture becomes finer behind, and there the punctation assumes 

 the form of striae. Pygidium protruding, triangular, black, coarsely 

 granulate.
