longei' than the pronotniii, very feebly convex, veiy broadly and feebly im- 

 pressed along the very slightly elevated suture, (inely, rather strongly and 

 densely, sub-aspei'ately and evenly punctate. Abdomen at base nearly as 

 wide as the elytra; sides parallel and ver2' feebly arcuate; surface very finely, 

 sub-asperately and den-^elj' p:inctate. Tj<'<is slender; anterior tarsi verj^ 

 slightly dilated; lirst joint of the posterior nearly one-half longer than the 

 second, sub-ecpial in length to the tifth. Length 3.5 mm.

The type is a male, tlie sexual characters being of the 

 same general order as in the preceding gronp of species, 

 although distinctl}' modified; the fifth segment is broadly 

 and rather feebly emarginato nearly throughout its width at 

 apex, the sides of the notch being very strongly convergent 

 and feebly incurvate, each having aporrected fringe of about 

 thirteen robust, closely-placed spinules; the median por- 

 rected process is very narrow, about one-half as wide as the 

 fimbriate sides, and exceedingly short, with the sides acute 

 and not broadly rounded as in the })recoding s])ecies; it is 

 broadly, roundly and rather strongl}' emarginate throughout 

 its width at apex, and has its surface smooth, glabrous and 

 conically impressed; sixth segment broadly and parabolic- 

 ally enuirginate at apex, the notch being twice as wide as 

 deep, and having the edge at the l)()ttom narrowly mem- 

 branous; seventii segment broadly divided. 



22 — L. mimula n- ^P — Form rather slender, intense black throughout except 

 the abdomen at tip which is sliLihtly paler; legs rather dark l)i-owuisli-Havate; 

 autruuai black at base, becoming dark fuscous toward tip; puliescence very 

 sparse anteriorly, long, coarse and rather sparse on the elytra, \evy line and 

 moderately dense on the abdomen; integuments i>olis!ied. Head moderate; 

 base truncate, angles rather narrowly rounded; sidrs parallel and nearly 

 straiglit; surface scarcely as wide as long, moderately convex, very linily, 

 moderately feebly and rather denselj' punctate; median line rather broad; 

 epistoma moderate in width, slightl3- produced, broadly and feebly arcuate at 

 the apex; antennal tuberculations small, rather prominent; labrum moderate 

 in size, teeth broader than long, scarcely deflexed, distinct; antenna; slightl}' 

 shorter than the head and prothorax together, basal joint rather robust. 

 Prothorax scarcely perceptibly narrower than the head, slightly longer than 

 wide; sides parallel, straight or verj' feebly sub-sinuate in the middle; base 

 broadly and feebly areuate, broadly sub-truncate in the middle; apex strongly
