THE CANADIAN ENTOMOLOGIST. 163 



densely, coarsely punctate throughout, granulate in front; clypeus broadly, 

 feebly emarginate, with a distinct denticle each side the ernargination ; 

 genae prominent, the angle scarcely rounded and nearly right. Thorax 

 nearly one-half wider than long, sides broadly arcuate and a little narrowed 

 posteriorly, hind angle obtuse as viewed from above, the sides and base 

 forming a continuous curve when viewed from the side. Surface densely, 

 coarsely punctate throughout, the punctures nearly or quite in contact at 

 all points, basal marginal line entire. Elytra as wide as the thorax, 

 humeri dentate, side a little arcuate, nearly parallel, stride moderate, 

 distinctly punctulate, iatervals moderately convex, the sutural with a single 

 row, the others with two rows of unusually coarse punctures, which are not 

 well defined toward the margin. The punctures occupy about one-third 

 the width of the interval, and are a little closer in the outer than in the 

 inner series of each ; those of the inner series being so close to the striae 

 as to render the inner margin of the interval somewhat crenate. Under 

 surface and legs very coarsely but not very closely punctate; mesosternum 

 not distinctly carinate between the coxae. Front tibia? tridentate, feebly 

 crenulate above the upper tooth ; hind femora with short marginal line 

 near the knee, hind tibia? without accessory spinule, the first tarsal joint 

 barely as long as the long spur. 



Length, 4.3 mm. One example, San Jose del Cabo. Type in the 

 collection of the California Academy. 



This species must stand next to abditus by Horn's table, but differs 

 very markedly by the larger, stouter form, and very coarse and dense 

 sculpture. Abditus has not yet been reported from the Peninsula, but may 

 reasonably be expected to occur there. 



Eburia semipubescens, n. sp. — Dark brown, head and prothorax 

 nearly glabrous, elytra uniformly but not densely clothed with a single 

 system of very short suberect hairs, beneath sparsely pubescent. Antennae 

 ( £ ) longer than the body, basal joint stouter and distinctly sulcate on its 

 anterior face, outer joints very slender, the nth about one-half longer than 

 the 10th. Prothorax as in Ulkei, sides with a moderately prominent 

 subapical tubercle and a median slender acute spine ; disk uneven, with 

 sparse, rather coarse but vague punctures. Elytra finely, moderately, 

 closely punctate, each with two small elongate basal and two similar 

 median ivory spots ; apex squarely truncate with sutural spine, the outer 

 angle distinct but not prominent. 



Length, 19 mm. — Colorado River, California. A single male.
