in its strongly pubescent upper surface, and closer and stronger 

 punctuation of pronotum and elytral intervals; its size too is 

 generally larger than viridis. 



I have examined all Macleay's types. Of these rugosculus, cyaneus, 

 vitticollis, and flavipes, appear to have been described from single 

 specimens, or very scanty material, and do not appear in other 

 collections. Rugosulus may readily be separated by its rugose sculp- 

 ture, and vitticollis by its colour distinction, though it may well 

 be an immature example of Ae ruficollis, with some adventitious 

 black marking. 



Ae cyaneus, Macl., may only prove to be a small dark variety of 

 viridis; at present it can be distinguished by its black pronotum. 



Ae flavipes, Macl., gives the appearance of immaturity. The 

 description is also misleading, stating the colour as " brownish- 

 black, opaque, the elytra nitid brassy-brown, the legs yellow"; 

 whereas the coloration is as follows : — Head and basal half of 

 antennae red, prothorax obscure, reddish above, clear red beneath, 

 elytra metallic but reddish; abdomen and tibiae red, femora pale 

 yellow. The pronotum is densely and confluently punctate; scarcely 

 " granulate." 



Atractus vittipennis, Macl., from its triangular intercoxal process, 

 smaller and more transverse eyes, thin first joint of antennae must 

 be placed in Chromomoea, near picea. Mad., and rufescens, Bates. 



Ae ruficollis, Macl., seems to be more generally known in collec- 

 tions. The colour variations I note as follows : — 



(a) Legs, dark. New Holland. Brit. Mus. 



(b) Abdomen with three basal segments red, apical segments black. 

 A second specimen has moreover the elytra margined yellow. 



(c) Head and prosternum black. 



The three specimens under (b) and (c) are labelled " Rockhamp- 

 ttni. Bates's Coll.," and have separate MS. names. 



Aethyssius atriceps, n. sp. 



Elongate, navicular, nitid, head (except labrum), antennae 

 scutellum, tarsi and underside (mostly) black, pronotum, elytra and 

 legs, also basal segments of abdomen red. elytra with a slight 

 metallic lustre. Head rather coarsely punctate, maxillary palpi 

 long, last joint narrowly cultriform, labium red. eyes large, reni- 

 form, separated by a space equal to the diameter of one, antennae 

 long, robust, joint 1 twice as long as 2, 'A longer than 4, 4-10 sub- 

 equal and obconic, last joint oval and about as long as 10.
