Hololepta vernicis Casey. 



In the Huachuca Mountains, Arizona, I took a small num- 

 ber of specimens of a Hololepa, which agree in every respect 

 with the description of this species. It is also a good species 

 and not synonymous with yucateca. The specimens are always 

 much smaller than yucateca, about the size of cacti, but more 

 elongate ; the lateral .thoracic groove is narrow and deeply 

 impressed, and scarcely becomes wider near apical angles; 

 near the latter in the male is a deep circular fovea, which is 

 absent in the female ; the supra-orbital striae are in all my 

 specimens short, basal. The description of the Mexican polita 

 Mars, fits the males of vernicis Casey very closely, in fact, 

 there is hardly anything in the description which does not 

 agree with my Arizona specimens, except that the subhumeral 

 stria does not extend quite to the base in my specimens. The 

 two will have to be united if there are not other characters 

 present to separate them. 



Hololepta (Lioderma) beyeri new species. 



Male. — Form and size of cacti Lea, but slightly narrower, black, shin- 

 ing. Mandibles elongate, feebly curved at apex, suddenly dilated 

 inside at about basal third, above the dilatation, one obtuse tooth, 

 surface finely punctulate. Head sparsely, rather coarsely punctate with 

 some finer punctures intermixed ; anteocular tooth indistinct ; supra- 

 orbital striae distinct. Thorax deeply emarginate at apex; sides feebly 

 arcuate ; lateral striae deeply impressed, but not broad, continued along 

 basal margin for a short distance; at sides, slightly below apical third 

 a deep transverse groove, above and below this a smaller one, which 

 two are more or less connected with each other by the marginal stria ; 

 near apical and basal angles the surface is moderately coarsely 

 punctate, disk smooth, with an impressed median line, which does 

 not extend to apex. Elytra as broad as the thorax at base; subhumeral 

 groove deeply impressed, not extending to base nor apex, coarsely, 

 sparsely punctate; first dorsal stria short, basal, deeply impressed, 

 below this a row of more or less distinct fine punctures; second stria 

 deeply impressed, entire, around which are a few coarse punctures at 

 apex. Propygidium rather coarsely punctate, punctures sparser at 

 middle and finer and denser at apex; pygidium more densely punctate 

 not margined. Labrum obtusely carinate on each side, and rather 

 acutely emarginate at middle. Prosternum convex, strongly com- 

 pressed and carinate in front of anterior coxse, acute at apex, broadly 

 dilated and flat behind. Anterior and middle tibiae quadridentate,
