half or more of antennae and metasternum infuscated or 

 black. With rather long, dark hairs, elytra with short, 

 whitish pubescence. 



Head with a large excavation between eyes, in its middle 

 a ridge crowned by a golden fascicle diverging to each side; 

 in front of the excavation a slightly hairy ridge, interrupted 

 in middle, a large and rather shallow depression in front; 

 with irregularly distributed punctures, base densely trans- 

 versely strigose. Antennae moderately long, most of the 

 joints serrated. Prothorax slightly longer than the greatest 

 width, a wide shallow depression near base; with a few 

 scattered punctures. Elytra about twice the length of pro- 

 thorax, each side at basal third with an obtusely triangular- 

 projection; with dense and sharply denned punctures, 

 becoming sparser on tips. Basal joint of front tarsi with a 

 small, black, inner comb. Length, 6-7 mm. 



Hab. — Northern Territory: Darwin (N. Davies and F. 

 P. Dodd). Type, I.' 11940. 



The head when viewed from behind appears to have two 

 tubercles, but these are less distinct than on C . purpurei- 

 pennis, and the ridges giving rise to them are differently 

 placed, the median fascicles are not black, as on C . fascicu- 

 latus and C. uncinatus, which also have the head differently 

 sculptured. The head, when viewed from certain directions, 

 appears to have a ridge from each side, not quite meeting 

 in the middle, the point where they would have joined being 

 overhung by the fascicles; in the male of C. armipennis the 

 lateral ridges meet at the central one, which is not fasciculate 

 in front, but some varieties of that species have a large part 

 of the base of elytra pale. On one of the specimens the 

 abdomen is entirely pale, and of a more reddish tone than 

 the other, some of whose basal segments are slightly 

 infuscated. 



Carphurus micropterus, n. sp. 



d . Black, elytra and legs piceous-black. With sparse,, 

 whitish pubescence, and long, straggling, dark hairs." 



Head wide; with dense and moderately coarse punctures. 

 Antennae not very long, basal joint rather large and swollen 

 at apex, second subglobular, third to ninth about as long as 

 second, but becoming acutely triangular on one side, tenth 

 and eleventh narrower, the eleventh scarcely longer than 

 tenth. Prothorax distinctly transverse, sides rather strongly 

 rounded, a narrowly impressed subbasal line; with numerous 

 sharply defined, but not very large punctures. Elytra short, 

 strongly narrowed posteriorly; with fairly dense asperate
