zons (Bates, coll. Gorham). 
On the single specimen collected by Mr. Champion it would be undesirable to found 
a new species, especially as I have seen South-American specimens which were insepa- 
rable from Colombian ones except by their much larger size. It is an obscure insect, 
with patches and fascize of grey hairs. 
Subfam. HY DNOCERIDES. 
HYDNOCERA. 
Hydnocera, Newman, Ent. Mag. v. p. 879 (1888). 
Hydnocera is the representative in the New World of a group of feebly formed but 
numerous species, of which Lemidia is the Australian type, those species referred to 
“¢ Hydnocerus”’ by Westwood and others from other parts of the world not having 
any close connexion with the genus. Making allowance for these, which must be 
eliminated, about thirty species have been described, extending in their range from 
the United States to Brazil. 
Section A. Elytra abbreviated and attenuated towards their tips. 
1. Hydnocera marginata. 
Hydnocera marginata, Gorh. Trans. Ent. Soc. Lond. 1877, p. 260°. 
Hab. GuateMaua, Aceituno | (Salvin). 
Var. capite prothoraceque plus minusve nigricante. 
Hab. GuatemMata, San Gerdénimo, Quiche Mountains (Champion); Panama, Boquete 
(Champion). 
‘The specimens taken by Champion, only one from each of the above localities, all 
vary; that from San Gerdénimo has the head and thorax entirely black, the suture 
broadly black in the middle, but the sides of the elytra quite pale. 
This may be the Hydnocera suturalis of Spinola (Atlas, t. 39. £6; Lf limbata, Spin. 
Mon. ii. p. 49). 
2. Hydnocera guatemala. (Tab. IX. fig. 3.) 
Hydnocera guatemale, Gorh. Trans. Ent. Soc. Lond. 1877, p. 261°. 
Hab. Guatemaua, near the city! (Salvin), Duefias (Champion). 
The four sepcimens from Duefias do not show any important variation from the type. 
One of them is figured in the Plate.
