AMERICAN COLEOPTERA. 33 



genera allied to Eurijmetopon and not with those in which the front is 

 trilobed. The notch on each side of the front is already known in 

 Eurymc.topon^ in fact I can see no character of importance separating 

 the two genera; the robust form, even, being already indicated by E. 

 cunvexico/le, Lee, and F. hicolor, Horn. Cryptadius should, in my 

 opinion, be suppressed into Eurym.rtopon. 



SCHIZIL.L.1JS, n. gen. 

 The above generic name is proposed for a form belonging to the 

 tribe Cri/ptoglossini^ allied more nearly to Cenfrioptera, from which it 

 differs only in having the genae much broader and the eyes completely 

 divided, the under portion of each eye very indistinctly granulated. 

 The mentum is broader than long, anteriorly truncate and feebly 

 emarginate at middle. Front hemi-hexagonal. The antennae are 11- 

 jointed, the first short and stout, invisible from above, terminal joint 

 broadly oval, stouter than the preceding. 



S. laticeps, n. sp. — Black, sub-opaque, moderately robust. Head sparsely 

 punctured, neck densely and finely granulate. Thorax broader than long, 

 apex moderately deeply emarginate, slightly broader than the base, sides 

 moderately arcuate, sinuate near the base, hind angles rectangular, base very 

 feebly emarginate, surface moderately convex, sparsely punctured and sub- 

 opaque and with a moderately deep, transverse, ante-basal impression. Elytra 

 oblong oval, not wider at base than the thorax, widest at middle, sides moder- 

 ately arcuate; surface moderately convex with rows of punctures on the disc 

 becoming irregular and sub-muricate at the sides and apexj intervals flat sub- 

 muricate punctate. Prothorax beneath sparsely punctate, presternum acutely 

 oval, slightly produced, margins slightly reflexed ; mesosternum nearly verti- 

 cal emarginate in front; abdomen sparsely and obsoletely punctate. Legs 

 black, sparsely muricately punctate. Tarsi stout. Length .75 — .90 inch; 23 mm. 



The thorax of this species is similar to that of Cryptoglossa laevis, 

 but less convex, while the elytra resemble in sculpture Elcodes conao- 

 hiina. The head is much broader than in any Centrioptera in our 

 fauna. 



The specimens, from which the above description was taken, were 

 captured by Mr. Crotch in the Mojave Desert, California.

E. vetorator, n. sp.— -Black, above sub-depressed, opaque,sparsely clothed 

 with short yellowish hairs. Form broadly ( 9 ) or more elongate ( 'J,) oval. 

 Head sparsely punctured and pubescent. Thorax nearly twice as wide at base 

 as long, apex emarginate not wider than the length of thorax, sides regularly 

 arcuate and gradually narrowed from base to apex, base squarely truncate, 

 surface feebly convex, opaque, sparsely punctured and pubescent. Elytra at 

 base very slightly broader than the thorax and slightly overlapped by it,
