506 COLEOPTERA 



Bostrum shorter than thorax, its median carina smooth and 

 shining. AntenncB pilose ; the two basal joints of the funiculus of 

 equal length ; club elongate-oval, densely pubescent. Prothorax 

 about as long as broad, widest before the middle, the sides gradually 

 narrowed behind ; somewhat uneven, with a more or less evident 

 longitudinal sulcus. Scutelhim minute. Elytra broader than 

 thorax, nearly tv^ice its length, humeral angles rounded, sides very 

 little curved, narrowed posteriorly ; striate-punctate (six discoidal 

 rows on each), interstices slightly convex, the sutural quite plane, 

 the third gradually elevated and terminating in protuberances on the 

 summit of the posterior declivity, apices projecting. Tibice densely 

 pilose towards the extremity. Underside clothed and sculptured 

 like the upper ; basal segment of abdomen broadly impressed be- 

 hind. 



Differs from I. imucs in possessing a rather shorter rostrum, a 

 thoracic groove, shorter hind-body of more oblong outline, less 

 attenuated and prolonged apically, and without distinctly raised 

 alternate interstices. In the female the hind protuberances are 

 nearly absent, and the apices are scarcely perceptibly produced.

Group- HYLOBIID^ . 



Eiratus (p- 447)- 



1619. E. omatus, ii-s. Ovate-oblong, sub-depressed, opaque, 

 fusco-piceous, tarsi and antennae (save the club) rufous, sparsely 

 clothed with bright-yellow hairs. 



Bostrum as long as thorax, punctate. Antenncd with a few fine 

 hairs ; scape gradually incrassated, densely and finely lineated ; 

 funiculus longer than club ; the latter oval and densely pubescent. 

 Prothorax longer than broad, abruptly contracted in front, the sides 

 straight behind ; somewhat uneven, rather coarsely but not closely 

 punctate. Elytra bisinuate at base, broader than thorax, twice its 

 length, the sides but little curved, narrowed behind ; each with six 

 discoidal rows of punctures ; interstices smooth, all more or less 

 obviously but interruptedly carinated, there being two or three 

 elongate and some smaller elevations on each, those on the third, 

 fifth, and seventh most conspicuous. Legs stout, with greyish hairs ; 

 the penultimate joint of the tarsi densely ciliated with elongate 

 white hairs. Underside pitchy, coarsely punctate, basal segment 

 of abdomen broadly impressed, apical segments paler. 



Most nearly related to E. costifer. The anterior contraction of 

 the thorax, the interrupted elytx'al costge, and consj)icuous clothing 

 render the species distinct. I think it likely that quite perfect ex- 

 amples of all the other species will exhibit the same dense fringe on 

 the second-last joint of the tarsi.
