median carina rather feeble and inconspicuously joined to 

 apical triangle; sublateral sulci partially concealed. Scape 

 about the length of four following joints combined; first joint 

 of funicle slightly shorter than second, none of the others trans- 

 verse. Prothorax almost twice as wide as the median length, 

 surface irregular and with two irregular transverse impressions. 

 Scutellum absent. Elytra subovate, sides rather strongly 

 rounded, with regular rows of large, deep punctures, partially 

 concealed in places; fourth, seventh, and tenth interstices 

 somewhat elevated. Leys comparatively long and thin ; 

 claw-joint unusually long and thin, claws conspicuously 

 separated throughout. Length, 9 mm. 



Hab. — Central Australia: Finke River (Captain S. A. 

 White). Type (unique), I. 5840. 



The claw- joint is thinner and about twice the length of 

 that of maculosus, but there are many other differences. The 

 type is probably somewhat abraded ; on the under-surf ace, 

 legs, and sides the scales are dense and uniform, except that 

 in places some of them have a silvery lustre ; on the prothorax 

 they are condensed into four irregular stripes (causing an 

 appearance as of three conspicuous dark intervening stripes), 

 on the elytra they are very irregularly distributed, and the' 

 apical slope has a curious transversely spotted appearance.
