distinctly nearer to base than apex; Ist joint of funicle thick, 

 more than half the length of 2nd, 2nd widening to apex, not as 

 long as three following combined, 3rd-7th distinctly transverse; 

 club rather small, subsolid, almost free. Prothnrax as in preceding, 

 except that the fascicles are a little less and the tubercles a little 

 more distinct, the constriction feebler. Elytra somewhat as in j^re- 

 ceding, base not depressed, shoulders with a tubercle from con- 

 tinuation of 5th interstice, 3rd tuberculate at base; suture on 

 declivity, 3rd and 5th interstices feebly raised; disc and sides 

 with rows of regular foveas. Abdomen as in preceding, but inter- 

 coxal process not concave, punctures or fovese less regular, inter- 

 mediates smaller, aj^ical witli. almost obliterated punctures. Legs 

 as in preceding, third tarsal joint still more feebly biloljed. 

 Length 6^, rostrum 1|; width 3 mm.

POROPTERUS DIFFICILIS, n.sp. 



Densely clothed all over with minute light brown scales, each 

 puncture of pro thorax (though not visible) marked by a thick 

 moderately elongate scale, a few also scattered about on interstices 

 of elytra, a feeble pale stripe at base of median line; elytra with , 

 paler scales on shoulders feebly continued on to prothorax, feebly 

 trimaculate at summit of declivity, scales of declivity a little 

 paler than on disc and marked almost at summit with a velvety- 

 black macula ; fascicles of 2nd interstice feebly marked and 

 several still feebler on 4th and 6th; under surface (except inter- 

 mediate abdominal segments) with elongate paler scales, palest 

 on meso- and metasternum; femora and tibije very feebly ringed 

 with darker scales; head and rostrum densely squamose. Cilia- 

 tion moderately elongate, bright silvery-yellow, visible with head 

 in position. 



Convex, tubercles very small. Head feebly convex; rostrum 

 feebly curved (in ^ almost straight), feebly widening to apex; 

 scape elongate, inserted about one-third from apex, fully half its 

 length passing muzzle (in ^ less); 1st joint of funicle more than 

 half the length of 2nd, 2nd as long as three following combined;
