44 Mr. Charles J. Gahan's Revision of 



This species is very closely allied to A. violaceipennis, 

 Thorns., and differs from it by characters of only minor 

 importance, such as the fuscous colour of the first two 

 antennal joints, and the sparser puncturation of the 

 prothorax. 



11. Astathes episcopalis. 



Astathes episcopalis, Chevr., Rev. eb Mag. de Zoo)., 1852, 

 p. 418. 



Head, thorax, body underneath, and femora, testaceous ; elytra 

 violaceous ; antennae black, with the bases of the 4th, 5th, Gth, and 

 of some of the succeeding joints, fulvous ; tibiae and tarsi black. 

 Puncturation variable ; the head being usually very closely, and the 

 prothorax less closely punctured ; but in some specimens the dorsal 

 tubercle of the prothorax is as closely punctured as the head ; elytra 

 somewhat closely punctured, but in some specimens much less so 

 than in others.

An example of this species in M. Oberthiir's collection 

 is ticketed " vioktceipennis, Thorns. Type," but is evidently 

 not the one described by Thomson under that name. 

 The true violaceipennis of Thomson appears to me, from 

 his description, to be identical with the species subsequently 

 described by him as nitida, and I think it not improbable 

 that the same specimen served as the type in each case, 

 the original label having, perhaps, been accidentally 

 removed from that specimen to one of episcopalis, Chevr. 



12. Astathes cyanoptera. 



Astathes cyanoptera, Gahan, Ann. Mag. Nat. Hist., (7) v, 

 p. 353 (1900). 



Closely allied to A. episcopalis, Chevr., but differing from it as 

 follows : — Less densely setose ; dorsal tubercle of prothorax very 

 sparsely punctured ; elytra cyaneous, somewhat more strongly 

 punctured ; proximal part of the tibiae testaceous ; tliird, fourth, 

 and fifth points of the antennae almost entirely fulvous, and the 

 underside of the first joint testaceous.
