404 Coleopterological Notices. 



This species is related only to contusum Lee, but differs greatly 

 in the upper surface of the elytra. In contusum the elytra are 

 nearly flat, sometimes feebly and transversely convex, the side 

 margins being very narrowly but abruptly reflexed, while in lami- 

 nation the upper surface is broadly, strongly concave throughout, 

 the concavity of the general surface extending unbroken to the 

 extreme edges; the etytral suture is however distinctly elevated, so 

 that it might be more proper to say that each elytron is concave ; 

 the humeral portion of the side margins is as usual a little more 

 strongly reflexed. The prothorax and the conformation of the 

 posterior angles are almost exactly as in contusum, except that the 

 sides are more widely reflexed. In contu&um the pronotum is fully 

 twice as densely asperate. 



EULABIS Esch. 



The species of this genus are not closely allied among themselves 

 and may be easily identified from the original descriptions; the 

 following species is, however, somewhat similar in appearance to 

 rujipes although twice as large. 



E. ci'itssicoruis n. sp. — Oblong-elongate, not pubescent, moderately 

 convex, dull, very dark rufo-piceous throughout, the legs just visibly paler. 

 Head moderate, about one-half as wide as the prothorax ; upper surface flat, 

 rather finely, extremely densely, confluently punctate throughout and dull ; 

 sides not perceptibly reflexed, the eyes rather depressed ; antennae not quite 

 as long as the bead and prothorax, very robust, strongly compressed and 

 incrassate toward apex, second joint much shorter and narrower than tbe 

 fifth, Prothorax about one-third wider than long ; apex but very slightly 

 narrower than the base, subtruncate, tbe apical angles narrowly rounded and 

 slightly prominent anteriorly; base truncate, very broadly, feebly sinuate 

 toward t lie basal angles which are not at all rounded and generally minutely 

 prominent, the sides being sinuate for a short distance before them; sides 

 strongly, evenly arcuate; disk feebly convex, rather depressed toward the 

 very finely reflexed side margins, somewhat coarsely, very deeply and densely 

 punctate, the punctures longitudinally coalescent. Scutellum not entering 

 the elytral disk. Elytra scarcely more than twice as long as the prothorax 

 and but just visibly wider than the latter, otherwise very nearly as in rujipes. 

 Abdomen densely very coarsely and deeply punctate, the setae rather long and 

 distinct. Length 7.0-7.8 mm. ; width 3.1-3.3 mm. 



California (southern). 



The lnentum is wider than long, trilobed at apex, the lateral 

 lobes acute and anteriorly prominent ; the surface is deeply biim-
