9 . Differs in having the propy- and pygidium larger 

 and paler and the abdomen and pygidium simple. 



Hab. — New South Wales: Galston (D. Dumbrell), 

 Sydney (A. M. Lea). 



Had I seen but one specimen of this species it would 

 probably have been considered as in some way damaged, or 

 possibly as abraded and immature; but as there are two of 

 each sex before me, with the same curiously livid colour, and 

 almost entirely glabrous surface, it appears desirable to name 

 them. The apical mucro is wider and shorter than in the 

 other species so armed, but it is quite distinct from the side. 



MlCROVALGUS SQUAMIVENTRIS, n. Sp. 



<$ . Black. Clothed with sooty scales, with a few white 

 ones interspersed, but white ones dense on scutellum, forming 

 a spot on each side of propygidium, and dense on parts of 

 under-surface. 



Prothorax about as long as wide. Abdomen with a wide 

 and rather shallow fovea on apical segment, at the sides of 

 and behind same a few long whitish scales, but on the three 

 segments before it there are numerous long erect scales, form- 

 ing loosely compacted fascicles. Length ( S , 9)> 4-4-| mm. 



9 . Differs in having the abdomen regularly convex, 

 with normally-adpressed scales. 



Hab. — New South Wales: Wollongong (A. M. Lea); 

 Victoria: Dividing Range, Bright (Blackburn's collection), 

 Warragul (J. C. Goudie). Type, I. 2227, in South Aus- 

 tralian Museum. 



A black species, at first sight apparently belonging to 

 nigrinus, but the males readily distinguished by the fascicles 

 of erect scales anterior to the fovea. One of the males has 

 five teeth to each of the front tibiae, the second and fourth 

 being smaller than the others, but its abdomen is the same 

 as those of the other males. Each of the three specimens 

 that I have identified as a female is without a line of white 

 scales along the middle of the py- and propygidium, such as 

 is usually present on the female of nigrinus, but many females 

 of that species are also without such a line. 



On this and all the following species the pygidium is 

 without an apical mucro. 



MlCROVALGUS NIGRINUS, Mad. 



d . Black. Clothing of upper-surface and sterna much 

 as on preceding species. 



Abdomen with rather dense white scales, nowhere elevated 

 or fasciculate ; apical segment with an almost perfectly cir- 

 cular, glabrous, and rather shallow fovea. Length, 3J-3-J mm.
