1. Egestrina sulcicollis. (Plate LXIV, fig. 10, £.) 



Egestria sulcicollis, Blackb., in Horn's Exped. pt. 2, p. 281 

 (1896). 



Hab. Central Australia, Ayer's Eock [type]; West 

 Australia (Duboulay). 



The type of this species is now in the British Museum, 

 which also possesses two similar examples ($) from W. 

 Australia. The specific name is misleading, the median 

 groove on the prothorax being only just traceable. 



2. Egestrina canescens, n. sp. 



Moderately elongate, rather broad, robust, shining (when denuded) ; 

 black, with a greenish lustre above, the basal joints of the antennae 

 in part and the anterior tarsi rufescent; thickly and uniformly 

 clothed with rather long, decumbent pubescence, which is flavo- 

 cinereous above and whitish on the under surface and legs, the 

 head and prothorax also with a few intermixed long, erect, fuscous 

 hairs; the head and prothorax densely, finely, the elytra more 

 coarsely, punctate. Head broad, the eyes moderately large; an- 

 tennae rather slender, about reaching the humeri, joint 3 much 

 longer than 2, 4-10 gradually becoming stouter, 11 ovate, a little 

 longer than 10. Prothorax as wide as the head, about as long as 

 broad, the sides rounded and somewhat dilated before the median 

 constriction, subparallel at the base, the basal groove narrow. 

 Elytra much wider than the prothorax, moderately long, subparallel 

 in their basal half. Legs rather stout. 



Length 7, breadth 2 mm. ($ ?) 



Hab. W. Australia, Swan Kiver (ex coll. Pascoe). 



One specimen, somewhat imperfect. Broader and more 

 robust than E. sulcicollis, Blackb., the vestiture denser, 

 the elytra more closely and not so coarsely punctate, the 

 eyes larger, the femora and tibiae almost black. The 

 upper surface has a greenish lustre in E. canescens, instead 

 of cupreous or brassy as in E. sulcicollis. This is doubtless 

 one of the unnamed insects mentioned by Pascoe in 1871 

 in his remarks on Egestria. 



Macratriomima, n. gen. 



Head small, flattened, truncate behind, and with a rather narrow, 

 short neck, the frontal suture distinct, the eyes small, widely separated, 

 distant from the base; terminal joint of maxillary palpi ovate, the
