Differs from the jireceding in tlie i'ollowinj^ characters : 



The unteniiae are very short; joints one and two large, three to eight very siiiall, 

 nearly globular and suhequnl, nine to eleven larger, sub-equal and forming a 

 loose dub. The spurs of the front tibiae are very minute and nearly ei|ual. Fifth 

 Joint of tarsi nearly doiilde the length of all llu; others. Korin gt^iierally a little 

 more convex. 



Perhaps tlie most reinarkiibli' difference is in the .seulpturo. wliidi can 

 lie very conveniently studied on the head of nritolis, it beinjr jrlabmus. 

 I found the head, under hifrh power, to be covered with miinite elonsrated 

 niarkinirs. the nature of which coukl not at first lie determined. Hy 

 chance the litrht was comintr very obli(|iicly. and it could be seen that one 

 side of thi' miirkin>rs was in deep shadow, the otlu-r beinir brijrhtly illu- 

 minated. The <lark side was tliat whirh was f,»rt;i...t from tlie source of 

 iii-dit. and proved the ornamentation to consist of .small, elonirated eleva- 

 tions; this form of sculpture is apparently uniijiie in our ('ucujidae. 



The antennae are very different in .structure from any in /,iini'>/)/ifti us. 

 and the terminal Joints do not seem to be ffatteiied. The protliorax is 

 transverse, a little lonjier than the head, with the .sides iircutite and un- 

 dulated. There does not ii|ipeiir to be any iipprecial)le sexual difference. 



Our species tire very small and ((uife unconunon ; they may be tabu- 

 lated as follows : 



tNdor iinitorm : t'ody glabrous above I. vcrnaliN. 



Elytra mottled with 'irgo patches of a paler tint; surface covered with exceed- 

 ingly short and sp se setae '2. pictllN. 



Color uniform : entire body covered with rather long and dense pubescence.
