DONACIAD/E HISPID/L. 227 



DESCRIPTION. 



Body underneath covered with a thick coat of silver pile as in the preceding species. Head 

 bronzed, hoary from cinereous down, minutely and confluently punctured, channelled between the 

 eyes with a longitudinal obtuse ridge on each side the channel ; antenna? black, bronzed at the base, 

 second and third joints equal in length ; mouth piceous : prothorax bronzed and gilded, rather longer 

 than wide, thickly and confluently punctured and wrinkled ; channelled ; sides longitudinally sub- 

 impressed ; anterior tubercles obsolete : scutellum hoary from down : elytra bronzed, gilded, punc- 

 tured in rows except at the apex where the punctures are confluent, two impressions adjoining the 

 suture, and one in the middle of the base ; apex truncated : ventral segments of the abdomen, the 

 last excepted, with a bright orange margin : posterior thighs with a stout short tooth. 



N. B. In the male the ventral segments are without the orange margin. 



Variety B. Prothorax bright copper, elytra black-bronzed. 



Family HISPID^. Hispidans. 



CXXI. Genus HISPA. Linn, 

 xxvi. * Subgenus Anoplitis. Kirb. 



Body without spines ; third joint of the antenna not much longer than the second : scape un- 

 armed. 



In the genuine Hispa, of wHich H. atra may be regarded as the type, the structure of the 

 antenna? is very different from that both of the other spinose ones, and of those that are without 

 spines ; the four first joints terminating externally in a spine, that of the scape being longer than 

 the rest and not being a prolongation of the external angle. In H. erinacea, and several other 

 American species, the third joint is very long, in Anoplitis it is scarcely longer than the second, as 

 in Hispa atra, but the four first joints are without the spine. We have therefore here types of 

 three subdivisions, viz. Hispa proper, Anoplitis, and Lobacantha, as I would denominate H. eri- 

 nacea and affinities, from the lobes crowned with spines which project from the elytra.
