472 CASEY 



ized by a large tumidity, bearing an elongate pubescent patch 

 surrounded by a convex margin, on the under surface of each 

 femur near the base, this being wholly wanting in the fe- 

 male. 



The transverse excavation of the fifth ventral is very large, 

 occupying nearly the entire segment, and has at the bottom an 

 obliquely elevated, flat, posteriorly trapezoidal surface feebly 

 emarginate at tip. The blackish-brown scales of the elytra 

 become whitish, although structurally unaltered, on the apical 

 declivity of many species. The forms then known to me were 

 briefly diagnosed recently (Can. Ent., 1907, p. 42) and, although 

 the status of some of them seemed doubtful, they appear to be 

 more certainly validated by additional material lately received, 

 the type of elongaitis being perfectly duplicated by two speci- 

 mens marked " San Diego," received from Professor Snow, the 

 two original examples of ovi^cnnis by another agreeing per- 

 fectly, marked " S. Cal.," on the label, and the original type of 

 scaber, collected by Dunn, by another marked "Julian." The 

 two original male types of lattpennis , characterized by a pro- 

 thorax unusuall}^ narrowed toward base and much narrower 

 than the elytra, are matched well by another specimen, female, 

 without definite locality. The following form is to be placed 

 near angustus: — 



Body very narrow and elongate, smaller in size, densely clothed through- 

 out with a gray-brown scaly indument not paler posteriorly, the 

 velvety spots of the elytra not black but a more reddish-brown; 

 head bi-impressed, sparsely tuberculose throughout ; prothorax a 

 little longer than wide, parallel and rounded at the sides in apical 

 three-fifths, then strongly, sinuously narrowed to the base, which 

 is relatively much narrowed and distinctly narrower than the 

 base of the elytra, the median parts of the surface moderately 

 elevated, sparsely strewn with coarse tubercles, the concave lateral 

 parts largely devoid of tubercles except toward the sides anteriorly ; 

 elytra two-thirds longer than wide and two-thirds longer and but 

 slightly wider than the prothorax, deeply sinuate at base, the sur- 

 face flat above, abruptly declivous at the sides and apex, very 

 roughly and irregularly pitted and with the tubercles small and 

 unusually remotely scattered throughout. Length 16.0 mm. ; 

 width 6.0 mm, California (locality unrecorded)... remotus n. sp. 



This species is represented before me by a single male, the 

 elongate pubescent area, at basal third of the femora, unusually
