]fl. Ulkei n. sp. — Form moderately robust, black, feebly shining, thorax and 

 elytra % variegated with a network of fine white pubescence, in the female 

 glabrous. Front sparsely punctate with extremely fine brownish pubescence, the 

 vertex near the border of the eyes with white pubescence. Scape of antennae 

 smooth, joints 3-4 narrowly annulate at base. Thorax wider than long, narrower 

 at apex, sides with a short but obtuse spine, in front of which the sides are oblique 

 and behind parallel, disc moderately convex, a slight depression above the spine, 

 with few scattered punctures and others more numerous in a transverse line in front 

 of base, surface clothed with extremely fine brown pubescence with a network of 

 white near the sides and base. Elytra oval, narrower posteriorly, the base trun- 

 cate wider than the base of the thorax, the humeri distinct, sides abruptly de- 

 clivous, disc feebly convex with numerous coarse and deep punctures not closely 

 placed, extending nearly to the apex and a little finer posteriorly, the sutural re- 

 "•ion not punctate and broader posteriorly, the defiexed portion of the elytra more 

 coarsely and closely punctured than the disc. Body beneath almost impunctate, 

 clothed with an almost invisible brown pubescence with small patches of white, 

 the bases of the femora and the coxse conspicuously white. Mesosternum deeply 

 grooved between the coxse. Femora smooth. Length .70-. 86 inch; 19-21.5 mm. 



The first three joints of all the tar.si are densely spongy pubescent 

 beneath. 



The females have the elytra much less punctured, and in one specimen 

 before me slightly wrinkled, the surface above without pubescence. 



Superficially this species resembles variolare, from which it difi'ers as 

 follows : the surface is less punctured and the pubescence white, not ful- 

 vous, the thoracic spine more distinct; the femora smooth, in variolare 

 coarsely punctate ; the humeri more prominent and the base of the 

 elytra broader. 



Feeling quite confident that this species difi"ers from any that are de- 

 scribed with similar ornamentation, I dedicate it to my friend Henry 

 Ulke, whose name I have already had occasion to mention. 



Occurs in Dimmit County, Texas ; given me by Mr. F. G. Schaupp. 



Jfl. variolare Thorns. — Form moderately elongate, black, shining. Front 

 sparsely punctate at the sides with dark brown pubescence above, vertex with 

 fulvous pubescence between the eyes. Antennae not distinctly annulate, the scape 

 and third joint sparsely punctate. Thorax wider than long, obtusely tuberculate 

 at the sides, apex slightly narrower than base, sides arcuate, disc moderately con- 

 vex sparsely coarsely punctate, more coarsely at the base and defiexed sides, sur- 

 face clothed with extremely fine brown pubescence with a network of yellowish 

 white or fulvous. Elytra oval, narrower posteriorly, longer in the female, the 

 base not or very little wider than the thorax, humeri very obtuse, sides abruptly 

 defiexed. disc slightly flattened with numerous coarse punctures not closely placed 

 which become finer posteriorly and attain the apex in the % , the 9 smooth at 

 apical third, the defiexed portion more closely and coarsely punctured, surface 

 clothed with extremely fine brown pubescence with an intricate network of ful- 

 vous pubescence, often entirely absent in 9 . Body beneath sparsely punctate,
