The genera of the CvjjhaleinaB are, with two or three excep- 

 tions, feebly .-separated from one another : the above has the 

 sculptured elytra of C>/j)/>(i/t-us] but the prothorax is expanded 

 at the sides, as in Chartopteryx^ from which it differs in the 

 two penultimate joints of the antennae being transverse (as in 

 Cjiphahms) and the anterior humeral angle rounded. I name 

 this handsome species after ^Ir. Masters, tlian whom none has 

 been more successful in collecting the animal productions of 

 Australia.

Differs from^. viridis, Bois. {Atractus), in its pubescence, 

 the sculpture of the elytra, the punctures in the strias being 

 smaller, less marked, and the transverse intervals between 

 them less distinctly separated by well-defined bars, which are 

 only seen in certain lights, and by the penultimate joint of the 

 posterior tarsi being longer and its sicles parallel nearly their 

 whole length. I have previously proposed ^thyssius for 

 Atractus, Lac, which is the name of an Hemipterous genus. 

 A. virescens and A. columhinus, Bois., are supposed to be 

 varieties of JE. viridr's, which varies from green to red and
