impressa: anus emarginatus'’. In the present species is 
only a single indentation at the base of the thoracic groo 
ve and immediately anterior to the scutel, and the anus is 
tridentated, the middle tooth being more slender and acu- 
te. A variety in my collection is destitute of the punctur 
ed striae of the elytra. 
4. B. obscura^ F. ( and Melsh. Catal.^ 
Herbst says the side of the thorax is rectilinear, not ar- 
quated. This would agree better with liirida, F.; my spe- 
cimens of obsciira are rectilinear only from before the mid- 
dle to the base. 
5. B. dentipes^ German This is the characteristica of 
Melsh. 
Catalogue. But as no mere catalogue can establish a na- 
me Gennar’s must be of course, retained, because it is the 
first name recognizable by a description. 
6. B. hyberncda^ F. From the specimen in my collec- 
tion,! am led to believe that the hybernata, F. is but a var- 
iety of the frontalis, Oliver, and that both have serrate ely- 
tra*; but I have not at present the means of referring to 
Olivier’s work. My specimen is reddish-purple; thorax 
immaculate: elytra serrate, with but five green spots and 
the anterior thighs are armed wdth a prominent tooth. 
7. B. Sexgutiata^ Nob. (Journ. Acad. Nat. Sc.) This 
name being preoccupied by Herbst for an American spe- 
cies, we change it Sexsignaia, 
8. B. gibbicolis, Nob. ('Journ. A. N. S.) This name 
is preoccupied by Illiger for an European species, it must 
therefore oe changed to 
9. Herbst. The volvulus, F. is prabably 
the same species; but which of the two names has the pn-

debted to the politeness of trie author.
