rather broadly rounded, basal slightly more broadlj' so; apical emargiuation 

 feeble, one-third as wide as the disk; the latter transversely and very mod- 

 erately convex, very finely, feebly and sparsely punctate in the middle, more 

 strongly and densely so near the sides, with a wide median impunctate area, 

 having a very small feeble impression near the base. Elytra at base distinctly 

 wider than the pronotum; sides parallel and ver}'' slightly arcuate; together 

 broadly and rather feebly sinuate behind; disk transversely and moderately 

 convex, narrowly impressed along the distinctly elevated suture, very finely, 

 rather densely and sub-granulosely punctate, scarcely one-fourth longer than 

 wide, two-fifths longer than the i)i'onotum. Abdomen at base very slightly 

 narrower than the elytra; sides parallel and feebly arcuate: surface very mi- 

 nutely, densely, irregularly and sub-asperately punctate. Legs robust; first 

 joint of the posterior tar^i one-third longer than the second. Length 4.3 mm. 



Santa Clara Co., 1 5 . 



The fifth ventral segment is broadly emarginate in its 

 middle, three-fonrths at apex, the emargination being 

 broadly rounded and six times as wide as deep; in the mid- 

 dle there is a short and very broad porrected process at the 

 bottom of the notch, which is broadly and feebly sinuate at 

 its apex, each side of the emagination having elsewhere a 

 porrected fringe of short, robust, very closely-^Dlaced spin- 

 iiles, about eleven in number; sixth segment deeply emargin- 

 ate at apex, the notch being parabolic in outline and slightly 

 wider than deep, exterior angles slightly rounded; seventh 

 narrowly divided. 



This species is distinguished from all the others in this 

 division of the genus by its rather large and very minutely 

 punctate head. The anterior tarsi are rather strongly di- 

 lated and clothed beneath with very short, pale, densely- 

 placed. papilla3. 



15— L. latiuscula n. sp. — Eather robust and depressed; head and abdomen 

 piceous-black, the latter very slightly paler at the apex; pronotum dark rufo- 

 fuscous; elytra much paler, rufous throughout; labrum, palpi and legs con- 

 colorous, pale reddish-flavate throughout; antennte fuscous; base dark rufous, 

 apex testaceous; pubescence very sparse anteriorly, long, very fine and rather 

 si>arse on the elytra and abdomen; integuments polished, very finely sub- 

 alutaceous. Head moderate, slightly wider than long exclusive of the labrum 

 "which is large and prominent; teeth very small, acute; base broadly truncate
