CURCULI0NIDE8. 281 



The covering of white hairs, with the three denuded spots dis- 

 tinguish this species. I have obtained it in Indiana as well as in 

 Pennsylvania. 



2. B. PicuMNUS Herbst. Natursyst. 



Vol. 7, p. 30, pi. 99, f. 9. This is a common species. The 

 third joint of the antennaj is hardly longer than the fourth. The 

 covering of hairs is more dense than in the preceding species. 



[Belongs to Centrinus Sch. — Lec] 



3. B. PENiCELLUS Herbst. Natursyst. vol. 7 ; p. 29, pi. 99, f 

 6F. 



Much like the preceding, but larger, and the third joint of the 

 antennae is as long again as the fourth. I described it under the 

 name of amicfus, but I have little doubt that it is the species de- 

 scribed by Herbst. Genus Toxerus Sch.? holosenceous Sch. Dej. 



[Also a Centrinus. — Lec] 



4. B. UNDULATUS. — Black ; elytra with two undulations. 

 Inhabits Mexico. 



Body black ; head with small punctures, sparse on the vertex, 

 more dense on the rostrum : rostrum arquated : thorax a little 

 compressed each side on the anterior margin : with rather large 

 confluent lateral punctures and smaller sparse ones on the disk : 

 elytra with capillary impunctured striae, becoming rather dilated 

 at tip ; interstitial spaces flat, with numerous transverse lines, a 

 dilated indentation or undulation before the middle, and rather 

 behind the middle, a less obvious indentation near the tip. 



Length over one-fifth of an inch. 



Var. a. Body dark brassy polished ; undulations of the elytra 

 obsolete. 



Length less than three-twentieths of an inch. 



The pectoral groove is very distinct, but the antennae are too 

 robust, and the club is too obtuse to be placed in the genus Cen- 

 trinus, and the fusiform club of Madams will not permit a refer- 

 ence to that genus. 



•5. B. STRIATUS. — Interstitial lines hardly wider than the striaB, 

 and with a single series of punctures. 



Inhabits United States. 



Body black, punctured : rostrum a little prominent at the in- 

 sertion of the antennae on each side ; more or less transversely in-
