in vagans, each ridge commences slightly behind the middle, 

 and is obliquely directed to a point slightly anterior to the 

 middle of the apex, but the two do not join; at its commence- 

 ment each is supplied with a small fascicle. The prothorax 

 also is not black as in vagans, although darker than the elytra. 

 The hind parts of the body are variable in colour. 



Microvalgus- nigriceps, n. sp., or var. of vagans. 



d . Black; muzzle, prothorax, scutellum, elytra, and 

 legs of a more or less bright castaneous. Shape and clothing 

 much as those of vagans. Length, 2^-3 mm. 



Hab. — Queensland: Dalby (Mrs. F. H. Hobler). 



The abdominal fovea is somewhat like that of vagans, 

 and is exactly the same at base, but with its hind margins 

 rounded and not divided off from the outer parts by oblique 

 ridges, although when seen from the side there appears to be 

 a fascicle at the apex. From bursarice it is also distinguished 

 by the abdominal fovea. The prothorax and scutellum, how- 

 ever, are of the same shade of colour as the elytra, whilst in 

 those species they appear to be always black, or at least 

 much darker than the elytra. The fovea of the preceding 

 species, when viewed directly from above, appears con- 

 spicuously margined posteriorly, by an oblique ridge on each 

 side ; on the present species when so viewed the ridges are 

 not traceable. The colour is much like that of the females 

 of castaneipennis, and of several other species, but the hind 

 parts of the body are black; the abdomen, however, is 

 obscurely diluted with red at the middle of the base. 



A male from Sydney possibly belongs to this species, 

 but has the prothorax slightly infuscated in middle, and the 

 under-parts infuscated instead of black, with the presternum 

 still paler. 



Microvalgus quinquedentatus, n. sp. 



9 . Dark-brown, some parts almost black, legs somewhat 

 paler. Densely clothed with scales varying from almost white 

 to chocolate-brown. 



Head with concealed punctures. Clypeus rather long, 

 moderately convex, apex narrowed and rounded; with dense, 

 distinct punctures. Prothorax almost as long as wide, sides 

 feebly decreasing in width from base to apex, but more 

 rounded in front, with the front angles rather feebly pro- 

 duced, sides shallowly depressed about middle, a feeble ridge 

 on each side of middle of apex, and an oblique one between 

 same and the side; punctures normally concealed. Elytra 

 short, widely depressed along middle, the depression gradually 

 narrowed from base to apex, sides oblique and rounded, with
