 44-.52 inch; 11-13 mm. PI. iv, fig. 2. 



A specimen which Mr. Ulke has loaned me is larger and 

 darker in color than any other I have seen, its mentum is 

 not pointed behind nor have the four posterior tibiae the 

 spine at middle, it, however, agrees in all other important 

 particulars, and I take it to be an abnormal specimen, espe- 

 cially as there are three sets of claws on the left anterior 

 tarsus, pi. iv, fig. 11. The trilobed form of the thorax is 

 certainly a very remarkable character which at once suggests 

 the similar structure of Hetcerius. 



Occurs in Kansas, Nebraska and Texas.

Black, subopaque. Head sparsely obsoletely punctate, not narrowed be- 

 hind the eyes, clypeus truncate or feebly bisinuate in front, wider between 

 the anterior angles than the head, margin moderately reflexed, angles 

 obtuse, vertex rather flat. Mentum transversely oval, pointed behind, very 

 deeply cupuliform, lateral angles very prominent. Thorax transversely 

 quadrate, broader at base, sides irregular, sometimes a little wider behind 

 the middle than at base, anterior angles obtusely prominent, pubescent 

 within, hind angles pyramidal, obtuse at tip, disc of thorax depressed, lateral 

 third more convex, the former more densely punctured, the latter less so, 

 the angles smooth. Elytra a little wider than the thorax, disc flattened, 

 at sides gradually rounded, surface with elongate foveae sparsely placed. 

 Pygidium coarsely punctured. Presternum behind the coxae slightly 

 elevated. Middle coxa contiguous. Body beneath opaque, coarsely but 

 sparsely punctured, abdomen with short yellowish hairs. Legs sub-fosso- 

 rial. Anterior tibiae bidentate near the tip, the apical tooth not much pro- 

 longed, middle and posterior tibia? flattened, broad, very little narrowed at 

 base, a small tooth at middle. Tarsi compressed, nearly as long as their re- 

 spective tibia?. Length .40-44 inch ; 10-11 mm. PI. iv, fig. 3. 



The mentum in some specimens is feebly notched as in 

 variolosus, but in others less acute and entire, so that the 

 present might be associated with that species. The division 

 of the disc of the thorax into three parts, although less dis- 

 tinct than in saucius, seems to indicate some relation between 

 them, although this is hardly supported by any other char- 

 acters. The form of thorax recalls somewhat that of Plega- 

 derus, and the hind tibiae, Psiloscelis. The peculiar charac- 

 ters of this species are — the broad clypeus, the point of
