9 . Differs in being larger (3|-4J mm.), with the legs 

 obscurely reddish, and abdomen strongly and evenly convex. 



Hab. — Queensland: Gayndah ; New South Wales : Tam- 

 worth, Blue Mountains, Jenolan, Wollongong, National 

 Park, Galston, Sydney, Bombala ; Victoria: Grampians. 



In general appearance close to the preceding species, but 

 the males easily distinguished by the abdominal clothing. I 

 cannot, however, find any structural details by which the 

 females of the two species may be distinguished. The male 

 has really a fairly wide depression along the whole of the 

 abdomen, but on the apical segment there is a large and cir- 

 cular glabrous space, with distinct punctures, which appears 

 as an isolated fovea; the scales surrounding it are perhaps a 

 trifle denser than elsewhere, but they are not at all raised 

 or fasciculate, nor are there any elevated processes, within or 

 at the sides of the fovea. Some of the scales are of a snowy- 

 whiteness on some specimens, but they are usually stram- 

 ineous. To the naked eye the scutellum usually appears as a 

 conspicuous, white, central spot, but on two cotypes (of which 

 there are six males before me) the scales there are sooty, but 

 they are matted together with gum, which often obscures 

 white scales. On the propygidium of the male there are nearly 

 always three distinct spots of pale scales, with a few sooty 

 ones between the spots; on the pygidium they are uniformly 

 whitish. But the pygidium of the female usually has some 

 sooty scales, with a median line of white ones. Some females 

 have the elytra and. mesosternal process obscurely diluted with 

 red. 



Microvalgus RUFiPENNis, n. sp., or var. of nigrinus. 



<S . Black; elytra and legs of a rather bright rusty-red. 

 Upper-surface with sooty scales, with a few whitish ones inter- 

 spersed, scutellum, propy- and pygidium and under-surface 

 (except abdominal fovea) with dense white or whitish scales. 

 Length, 3-3Jr mm. 



Hab. — Australia (Blackburn's collection); New South 

 Wales: Wollongong (A. M. Lea) ; Victoria: Gisborne (H. H. 

 D. Griffith). Type, I. 2228, in South Australian Museum. 



The abdomen of the male is exactly as in nigrinus, but 

 as the elytra and legs are conspicuously reddish, and the pro- 

 pygidium ( 51 ) and pygidium are uniformly clothed with pale 

 scales, I have ventured to describe it as new. There are gen- 

 erally a few white scales about the tip of the elytra. 



A female, carded with two males, from Wollongong, pos- 

 sibly belongs to this species. Its prothorax is of a dull-red, 



(51) On one of the five males before me the propygidium is feebly 

 trimaculate.
