ART. 27 NEW BUPRESTID BEETLES FISHER 5 



Length, 9.75 mm; width, 3.25 mm. 



Type locality. — Los Mochis, Sinaloa, Mexico. 



ry^e.— U.S.N.M. No. 49552. 



Remarks. — Described from a unique male collected July 2, 1924, 

 by R. W. Van Zwaluwenburg. 



This species resembles ohieyae Skinner, but it differs from that 

 species in being more elongate, more strongly acuminate posteriorly, 

 and by the different arrangement of the reddish-yellow spots on the 

 elytra. 



AGRILUS RUFOBRUNNEUS, new species 



Female. — Rather robust, slightly flattened above, and moderately 

 shining; above and beneath dark brown, with a distinct reddish- 

 cupreous tinge, and each elytron ornamented with a vague, longi- 

 tudinal, whitish pubescent vitta, extending from basal depression to 

 near the apex. 



Head with the front rather wide, slightly convex, about equal in 

 width at top and bottom, lateral margins parallel, and with a broad, 

 longitudinal depression extending from epistoma to occiput, the 

 depression distinctly deeper and broader on the vertex and occiput; 

 surface coarsely, deeply, irregularly rugose, the rugae more or less 

 concentric on the occiput, sparsely punctate between the rugae, and 

 sparsely clothed with short, semierect, white hairs ; epistoma strongly 

 transverse between the antennae, strongly elevated, and broadly, 

 deeply, arcuately emarginate in front; antenna short, serrate from 

 the fifth joint, the outer joints transverse; eyes rather large, and 

 more acutely rounded beneath than above. 



Pronotum about one fourth wider than long, about equal in width 

 at base and ajjex, and widest at apical fourth; sides arcuately ex- 

 panded" from apical angles to apical fourth, then obliquely nar- 

 i-owed to the posterior angles, which are rectangular; when viewed 

 from the side the marginal and submarginal carinae strongly sinuate, 

 widely separated anteriorly but joined near the base; anterior margin 

 strongly sinuate, with the median lobe strongly, broadly rounded; 

 base strongly, angularh' emarginate at middle of each elytron, with 

 the median lobe broadly rounded, and transversely truncate in front 

 of the scutellum ; disk strongly convex, feebly, broadly, transversely 

 flattened behind the middle, with a rather deep depression on each 

 side extending obliquely forward to the lateral margin near middle, 

 and with a rather strongly elevated, oblong swelling replacing the 

 prehunieral carina near each posterior angle; surface coarsely, 

 deeply, irregularly rugose, the rugae concentric on each side of the 

 middle near anterior margin, finely, sparsely punctate between the 

 rugae, and sparsely clothed with short, semierect, white hairs. 

 Scutellum feebly, transversely carinate, the surface finely reticulate.
