joints taken together. The extreme base of each elytron, close to 

 the scutellum, is armed with a conical tubercle, and the extreme 

 apex is slightly truncated. 



Other species of Zygocera are described by Erichson (Wiegm. 

 Arch. 1842), and Pascoe {ante, pp. 5*il, 542). 



Genus Abryna. 

 This genus was first indicated as *' genus novum ?" by Mr. 

 Newman in the Entomologist, p. 289.* In the few characters 

 assigned to the genus, we find the eyes described as "ad antenna- 

 rum basin fere divisi," whereas they are widely divided apart in a 

 specimen of the type 



Sp. 1. Abryna ccenosa, Newm.-|~ (PI. XXV. fig. 3), 



in the Hopeian collection, the narrow ridge behind the base of 

 the antennae, forming in fact the edge of the excavation in which 

 the rotula of the antennae works, being quite destitute of facets ; 

 the elytra are also said to be "apice trunctata, truncatura concava," 

 which is indeed the case with the type specimen in the British 

 Museum, which is evidently a large male, but in the specimen of 

 A, ccenosa before me the truncation is even slightly convex. The 

 peculiar character of the tuberculated anterior angles of the pro- 

 thorax is found in 



Sp. 2. Abryna fausta, Newm.J (PI. XXV. fig. 4), 



in which the elytra are glossy purplish blue ; but here, as described 

 by Mr. Newman, these organs are "apice rotundata," disagreeing 



* " Genus novum ? Antennae valde distantes, corpore vix breviores, articulus
