a little advanced ; it has a longitudinal sulcate in the middle, and 

 a transverse impression in front and behind ; its surface is marked 

 with transverse striola?, and its posterior margin with longitudinal 

 ones ; elytra having their posterior part rather rugous ; inferior 

 part of the body of a i-ather brilliaiat black." 



" Swan Kiver." 



From M. Putzeys' Revision we learn that it is a more narrow 

 species than A. concolor, the breadth being 7^ mm. ; that the 

 labrum is emarginate, and that the anterior tibiae are more 

 decidedly dilatate at the apex. 



AdOTELA ESMERALDA. 



A. esmeralda, Casteln. I.e., p. 175; Putz. Revis. 1873, p. 340. 



De Castelnau's description of this species is very poor ; and 

 M. Putzeys has merely a short notice of it in his Revision, of 

 which the following is the substance : — 



Black, with the elytra of a beautiful metallic green, the sides of 

 the head and prothorax the same. The form is rather like that 

 of A. concolor, but the prothorax is narrower and longer, more 

 narrowed to the base where the angles are more decided ; the 

 elytra are less oval, their sides are more parallel. The two first 

 joints are spongious below in the ^. 



Length 20, elytra 11, breadth 7^ mm.

Adotela bicolor. 



Parroa bicolor, Casteln, I.e. 174. 



This species was described by de Castelnau from a specimen in 

 Dr. Howitt's collection, and was unknown to M. Putzeys, who, 

 not having seen it, does not remark on it. The following is de 

 Castelnau's exceedingly brief descrii)tion : — 



" Length 7', brilliant, of a fine purple, with the elytra green ; 

 thorax globular, with the margin green ; elytra smooth, with a 

 few granulations on the posterior part of the margin ; antennje, 

 mouth, and legs black, the latter with rugous hair."
