species, broader and more convex in form tban any of the others, 

 and with the elytra narrowed from apical third, more narrowly sub- 

 truncate and broadly arcuate at apex. The head is transverse, with 

 the eyes moderate in size and strongly convex, the antennae stout, 

 nearly normal in size and structure but with the club parallel, the 

 epistomal suture very fine and scarcely perceptibly impressed. The 

 prothorax is much wider than long, nearly as wide as the elytra, 

 feebly narrowed from apex to base and with the sides feebly, evenly 

 arcuate throughout, the disk being feebly impressed in the middle 

 toward base. The elytra are not quite twice as long as wide, 

 very coarsely deeply and confusedly punctate, the punctures toward 

 base becoming dense and subcoalescent. The abdomen is polished, 

 minutely and sparsely punctate, the prosternum polished, rather 

 strongly but sparsely punctate, the process being rather broad 

 between the coxae. The anterior tibiae have the exterior apical 

 angle prolonged outwardly and acute. The head and pronotum 

 are rather coarsely and densely and unusually deeply punctured, 

 and each puncture of the entire upper surface bears a short robust 

 erect seta, which is coarsely plumose or bushy in structure. The 

 feebly marked epistomal suture, parallel antennal club and peculiar 

 vestiture may perhaps warrant the generic isolation of this species, 

 in which event the name Trogoxylon Lee. could be appropriately 

 adopted for it.

The following species belongs near webbi Lee, but is much 

 larger : — 



C. apaclieanilS n. sp. — Moderately slender and convex, smooth, 

 polished, intense black throughout, clothed rather densely with small robust 

 recumbent and squamiform hairs, which are strongly convex and finely 

 pointed, dark bluish in color, giving a deep violet-blue bloom to the surface, 

 the lateral edges of the pronotum rather broadly, and of the elytra very 

 narrowly, clothed with dense white recumbent pubescence, the white border 

 abruptly limited. Head strongly impressed, rather coarsely, deeply, sparsely 

 punctate, the interspaces very finely, densely punctate ; antennae short, two- 

 thirds as long as the prothorax, pruinose with violet-blue, the third joint but 

 slightly shorter than the fourth. Prothorax one-fifth longer than wide, in form 

 nearly as in webbi, very finely, moderately closely punctate throughout and 

 with scattered coarser punctures anteriorly, especially toward the sides. 

 Scutellum a little wider than long, polished. Elytra in form and relation to
