612 Coleopterological Noticen, VI. 



Pronotal punctures rather coarse, sparse and unevenly disposed, the surface 

 wholl}' impunctate in hirge areas before the middle of the disk. 



areiiariu!« Csy. 



Pronotal punctures coarse and rather close-set throughout the disk, though 



l^nevenly distributed; body very much more broadly oval...latlls n. sp. 



Pronotal punctures fine and sparse, somewhat evenly distributed over the 



entire disk. 



Body elongate-oval ; sides of the prothorax rather feebly arcuate. 



ciliatus Esch. 

 Body short and ])road, the elytral asperities smaller, more distinctly de- 

 fined and more isolated; sides of the pi'othorax strongly arcuate; head 

 relatively smaller in size Clirtlllus n. sp. 



All of the species have long coarse hair well developed along 

 the sides of the body, its function probabl}- being to maintain the 

 spiracles free from sand while burrowing. 



C. lattlS. — Very broadlj* oblong-elliptical, moderately convex, polished, 

 'deep black, the legs dark piceo-rufous; palpi and antenniE paler, testaceous, 

 the labrum blackish; pubescence very short, sparse, yellowish, becoming 

 long at the sides of the body, short and very stifl' on the legs. Head not two- 

 ■fifths as wide as the prothorax, coarsely and densely jiuuctured, less closely so 

 'on the epistoma, subimininctate toward base, the ei)istomal suture marked l)y 

 a deep transverse channel; apical sinuation very broad and feeble; antenna? 

 with the club three-jointed and feeble, the joints strongl.y transverse, the last 

 narrower as usual. Prothorax distinctly more than twice as wide as long; 

 apex one-half as wide as the base and deeply emarginate, the angles narrowly 

 xounded; sides strongly convergent from the base, arcuate, more strongly so at 

 "base, the basal angles obliterated; base transverse and almost rectilinear 

 throughout, with the usual fine coriaceous margin; disk coarsely deeply and 

 conspicuously punctate, the punctures generally rather close-set but uneven in 

 •distribution. Elytra barely as long as wide, about twice as long as the pro- 

 thorax, coarsely asperate and polished. Length 7.7 mm. ; width 4.8 mm. 



California (San Diego). 



At first sight this species might be mistaken for globosus, but 

 may be readily distinguished l)y its ver}' much more broadly 

 rounded form and very shallow epistomal sinus. 



C. ciirtiillis. — Broad and oblong-oval, convex, polished, the elytra dull 

 toward apex, ))lack, the under surface and legs dark rufo-piceous, the trophi 

 and antcnntc still paler and rufous; surface glabrous except posteriorly and at 

 the sides of the body. Head rather small, barely two-fifths as wide as the pro- 

 thorax, roughly sculptured, the epistoma smoother, the suture deep; apical 

 sinus broad and feeble but stronger than in ciliatus ; labrum feeblj- sinuato- 

 truncate at apex. Prothorax short and transverse, slightly more than twice 

 as wide as its greatest length, the apex more than one-half as wide as the base;
