ART. 27 NEW BUPKESTID BEETLES FISHER 43 



Pronotum moderately convex, two and one half times as wide as 

 long at base; distinctly narrower at apex than at base, and widest 

 at base; when viewed from above the sides arcuately expanded at 

 base, then arcuately narrowed to the apical angles ; posterior angles 

 rather acutely rounded and feebly projecting; anterior margin 

 feebly, broadly, arcuately emarginate ; base feebly, transversely sin- 

 uate to middle of each elytron, then turning obliquely backward to 

 the scutellum, in front of which it is vaguely, arcuately emarginate; 

 surface feebly, broadly flattened toward the sides, glabrous, densely, 

 finely reticulate at the sides, smoother on median part, and sparsely, 

 coarsely, irregularly punctate. Scutellum large, triangtdar, anterior 

 margin vaguely rounded, the surface nearly smooth. 



Elytra moderately convex, uneven, as wide as pronotum at base ; 

 humeral angles obtusely angulated; sides nearly parallel to basal 

 third, then strongly, arcuately narrowed to the tips, wdiich are con- 

 jointly broadly rounded, with the lateral margins vaguely serrate; 

 humeri prominent; surface glabrous, sparsely, finely, irregularly 

 punctate on apical halves, with numerous small, irregularly ar- 

 ranged, depressed areas on basal halves, the depressions finely reticu- 

 late, each elytron with a large, rounded elevation behind the scutel- 

 lum, a similar one along the lateral margin at middle, and an 

 elongate elevation at apex. 



Abdomen beneath finely, densely reticulate, sparsely, rather 

 coarsely, irregularly punctate, and sparsely clothed w'ith short, re- 

 cumbent, white hairs; last segment broadly rounded at apex, with 

 the apical groove deep and following the outline of the lateral mar- 

 gins. Prosternum finely, densely reticulate, the anterior margin 

 subtruncate or vaguely rounded ; prosternal process narrow, sparsely 

 punctate, the sides feebly, broadly constricted at the coxal cavities, 

 broadly rounded at apex. 



Length, 2.75 mm; width, 1.35 mm. 



Type locality. — Real de Arriba, Mexico, D.F. 



ry;?e.— U.S.N.M. No. 495Y6. 



Paratype. — In the H. E. Hinton collection. 



Remarks. — Described from two males (one type) collected at the 

 type locality at an altitude of 6,300 feet, during July 1932, by 

 H. E. Hinton. 



This species resembles splendens Fisher, but it differs from that 

 species in having the front of the head more deeply depressed and 

 the elytra very uneven. 



LIUS SPLENDENS, new species 



Male. — Elongate, broadly cuneiform, moderately convex, strongly 

 shining; head and pronotum cupreous, the former feebly aeneous
