AMERICAN COLEOPTERA. l25 



cinereous and browuish pubescence, sides arcuate before tlie spine which is 

 small, acute and abruptly formed. Elytra densely clothed with grey pubes- 

 cence, surface very distinctly but not densely punctured, and with five regular 

 series of small black spots which are slightly tuberculate and bear small tufta 

 of scale-like hairs, a larger black space at the side in front of middle and two 

 fasciae, one slightly behind the middle forming at the suture an acute angle, 

 the other posterior and less oblique not attaining the suture. Body beneath 

 and legs with whitish pubescence, the latter maculate. Length .36 inch ; 

 9 mm. 



Resembles variegatus in form but the elytra are a little more 

 convex, it differs especially in the more convex front and the pres- 

 ence of erect scales on the elytra. The characters of the table will 

 distinguish it from those which follow. 



One specimen % , Texas, kindly given me by Mr. Chas. Wilt to 

 whom it is dedicated, whose many kind donations to my cabinet have 

 been of great assistance in the prosecution of my studies.

I have referred to this species some forms collected in Texas by 

 Mr. Schwarz, which are as follows : 



Elytra with faint oblique discal impression, surface clothed with cinereous 

 pubescence and with moderately coarse punctures which gradually become 

 effaced toward the tip which is feebly obliquely truncate, disc very faintly 

 tricostate. the costse with distant faint tubercles which bear on their summits 

 Bcale-like hairs, external to the faint costse are two other rows of distant 

 darker tubercles, the sutural elevation also tuberculate, at the apical third is 

 a common, arcuate, narrow, black fascia convex to the front, exterior to which 

 is a short oblique line. Length .26 inch ; 6.5 mm. 



The type specimen of this species from Lower California is some- 

 what shorter and the surface slightly abraded. The costae are very 

 much feebler and the darker spots less evident. The arcuate fascia 

 exists in a feeble trace but its position is sufficiently well marked. 

 Either form bears a considerable resemblance to Leptosti/his buistus, 

 and they approach that genus in having a wider pro- and meso- 

 sternum than is usual in Liopus. 



With this note of the differences I leave for future collections in 

 the Peninsula the settlement of the question of the identity or not 

 of the two forms.

 eyes above considerably separated, at the base of the antennae and behind 

 them two impressed lines forming a cross; thorax above varied with cinereous- 

 elytra very thickly punctured; a large ash-colored squarish irregular mark 

 before the middle and with projecting corners, a spear-shaped cinereous mark 

 near the tip; the tip notched on each side near the suture. Leugih 4 linea.
