the elytra being gradually narrowed from the base : in all those above described 

 the body is regularly oval, beng equally obtuse at each end. The antennae of 

 the male are strongly pectinate, those of the female are terminated by a small 

 four-jointed club.

Louisiana, given me by Mr. Guex. Considerably smaller than the preceding, 

 more obtuse anteriorly, hardly narrowed posteriorly, and with the hairy spots 

 of the elytra forming distinct transverse undulated lines. The antenna? of the 

 male are strongly pectinate.

San Diego, California. From the fasciate elytra, this species has the appear- 

 ance of Trogoderma, but the antennas are terminated by a very large two-jointed 

 club, which is received in an excavation just within the lateral margin of the 

 thorax. 



2. C. t r i s t e , subovatum nigrum, subtiliter cinereo-pubescens, thorace 

 sat dense subtiliter punctulato, elytris confertim punctulatis, antenrarum basi, 

 tibiis tarsisque piceis. Lonj. -10 -13. 



San Jose, California. Somewhat ovate in form, more obtuse behind than in 

 front, but broadest about the base of the elytra. The hair is fine, and dark 

 colored, although not sparse; the punctures of the thorax are not distinct, but 

 those of the elytra are quite obvious. 



Closely allied to this species must be Anthrenus a p i c a 1 i s Mann. Bull. 

 Mosc. 1843, 258. It is also from California, and (by description) differs from 

 the species here described, by the tip of the elytra, and the feet being reddish.

 subtiliter punctulato, elytris confertim punctulatis, antennis tarssique piceis.

Pennsylvania to Georgia. A little broader and somewhat less convex than 

 the preceding, but very similar to it in characters ; the pubescence appears also 

 less dense. The base of the antennae is sometimes testaceous; the tibiae appear 

 to be always black.

 thorace vix punctulato, elytris punctulatis, antennis tibiis tarsisque obscure

Southern States. Easily distinguished by the less abundant pubescence, the 

 almost smooth thorax, and the reddish brown antennae. 



5. C. hemorrhoidale, subovatum, nigrum, subtiliter cinereo-pubes-

Middle and Southern States. In this and the preceding species, the middle of 

 the base of the thorax is more suddenly produced than in C. picicorne, or C. 

 triste. The apical spot of the elytra occupies nearly one third of the surface ; 

 the cinereous pubescence at its anterior portion and at the tip is more dense : 

 occasionally on each elytron, near the middle of the spot, may be observed a 

 fuscous dot. 



6. C. fusculum, subovatum, nigrum, densius cinereo-pubescens, thorace 

 subtiliter punctulato, elytris punctatis, (saepe rufescentibus, macula communi 

 basali triangulari picea,) antennis pedibusque rufis. Long. "06 OS.
