and speaks of the colour as ‘“fuscus vel fusco-ferrugineus.” Our specimen, moreover, 
is not quite perfect, and, under the circumstances, I do not like to separate it. 
The specimen from the Stockholm Museum is figured. 
2. Platycentrus obtusicornis. (Tab. IX. figg. 11, 11a.) 
Platycentrus obtusicornis, Stal, Ofv. Kongl. Vet.-Ak. Forh. 1869, p. 291°. 
Hab. Mexico (Mus. Holm.'), Jalapa (Hoge). 
This species may be readily distinguished from the preceding by the broad and blunt 
horns, which, if viewed from the front, are strongly deflexed at the apex. 
Through the kindness of Dr. Aurivillius, I have been enabled to verify these two 
insects by comparison with typical specimens in the Stockholm Museum. 
The specimen from Jalapa is figured.

Hab. Meuxico (Mus. Holm; Mus. Vind. Ces.; Mus. Brit.). 
The pellucid elytra and bright orange legs will easily distinguish this species, which 
in general appearance and size is allied to Campylocentrus; it is not represented in 
our collection. 
CAMPYLOCENTRUS. 
Campylocentrus, Stal, Ofv. Kongl. Vet.-Ak. Forb. xxvi. p. 289 (1869). 
According to Stal’s arrangement this genus appears to be somewhat heterogeneous, 
containing Centrotus curvidens, Fairm., and C. subspinosus, Fairm., as well as C. hamifer, 
Fairm. (nec Walk.), and its allies. In general facies, however, and in other respects, 
the first two species seem abundantly distinct.
