I have not ventured to identify the female of this species, 

 of vaganSj fasciculatus, or of nigriceps, amongst the many- 

 unplaced females under examination. 



MlCROVALGUS MUCRONATUS, n. Sp. 



d • Black. Clothed with white or whitish scales, dense 

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

 sparser elsewhere, and on prothorax and elytra mixed with 

 sooty ones. 



Prothorax quite as long as wide, sides almost parallel. 

 Pygidium with a triangular process projected backwards at 

 tip. Abdomen with a wide and rather shallow depression, 

 across the apex of same with a feeble curved process, crowned 

 with short ferruginous setae, becoming paler and subfascicu- 

 late on sides. Length, 2|-2f mm. 



Hab. — North Queensland and Mackay (Blackburn's col- 

 lection), Coen (H. Hacker), Cairns (E. Allen). Type, I. 

 2229, in South Australian Museum. 



With a mucronate pygidium as in the two preceding 

 species, but elytra black, and abdominal depression different 

 at apex. From the other black species it is readily dis- 

 tinguished by the pygidium. The spurs to the hind tibiae are 

 rather shorter than usual. The sooty scales on the upper- 

 surface appear almost white from certain directions. On some 

 specimens the tarsi are reddish. The specimen from Mackay 

 is less densely clothed than the others, but appears to have 

 been partly abraded. 



The only specimen before me which with some confidence 

 may be identified as a female of the species is from Cairns, 

 and differs from the males in having the abdomen (basal 

 segments infuscated), propy- and pygidium of a rather pale 

 red, with the scales of a rather dark stramineous, and on the 

 propygidium mixed with a few sooty ones, the legs diluted 

 with red, and the pygidium and abdomen simple. 



MlCROVALGUS GLABER, n. Sp. 



d . Of a dark livid-brown, head and prothorax blackish. 

 Glabrous except for a few scattered scales about tip of 

 abdomen and on sides of suture. 



Head with feeble punctures. Prothorax about as long 

 as wide, with a small depression near the middle of each side ; 

 punctures very shallow. Elytra with feeble punctures and 

 striae. Pygidium obtusely mucronate at tip. A bdomen widely 

 and shallowly depressed along middle, the depression at apex 

 with a transverse space clothed with short setae. Length, 

 2f-3J mm.
