AO&OCERA.— HALECIA. 5 



the elytra is not coppery. The thorax has the discoidal portion shining and very 

 slightly tinted with coppery, rather more distinctly coriaceous than in A. gigas, with 

 the strong punctures more numerous ; the sides are very closely and rugosely punc- 

 tured ; the middle channel is not very deep, and is less closely, but more strongly 

 punctured than in A. gigas, the lateral channels are very rugose. Each elytron has a 

 short obtuse costa near the scutellum, united to the raised suture not far from the 

 base ; there is then a costa which extends only for two thirds the length of the elytron 

 the next costa extends nearly to the apex, becoming much attenuated posteriorly ; the 

 next is very short and slightly interrupted ; the sub marginal costa extends to the apex ; 

 all the interspaces are very closely, rather finely, and rugulosely punctured ; the elytra 

 are not quite contiguous at the apex; the lateral margins at the apex are scarcely 



crenulate. 



EUCHKOMA. 



Euchroma, Solier, Ann. Soc. Ent. Fr. ii. 1833, p. 284. 



This genus contains the largest known species of this family. The species are found 

 in Mexico, and as far south as Brazil.

 by the crenulation of the margin of the elytra near the apex. 



"■ HALECIA. 

 Halecia, Lap. & Gory, Mon. i. Bupr. p. 108. 



This genus, as at present constituted, is found throughout America, from Pennsylvania 

 to Patagonia ; but the species are most numerous in Brazil ; several are recorded from 

 the West Indies. 



l. Halecia chrysodemoides.

Hab. Nicaeagua, Chontales 1 (Belt). 



This is one of the section of species of Halecia which have the thorax not angular 

 at the sides near the base. It is nearly always golden-green ; but one example before 

 me is tinted above with a coppery hue. The type specimen has the costse on the elytra 

 blue-green ; but other examples have them of a purple-coppery colour.
