agrees with yours in shape (also in sloping more gradually behind), 

 and has the tibial brush, though slightly less developed. It is from 

 Gascoyue." 



From tlie above, it is fairly certain that my Swan River speci- 

 men belongs to C. acromialis, and as, in its clothing, it differs 

 rather considerably from the description of the type, I here give a 

 description of the clothing, together with the chief points of dif- 

 ference between it and C. tibialis. 



9. (Swan River). Clothing with the light portion forming a 

 longitudinal band along each side of dorsum of head, prothorax and 

 elytra, median line of prothorax with a similar though narrower 

 vitta, disc of elytra mainly clothed with intermingled greyish and 

 ochraceous subpubescence, centre of head, prothorax (except vit- 

 t£e), irregular macules on elytra, especially near declivity, black. 

 Prothorax with smaller granules than in C. tibialis, more obscured 

 by clothing, apparently absent along vittse; elytra with granules 

 smaller basally, larger, almost tuberculiform, about declivity, these 

 most marked on second interstice, less so on third and fourth; 

 tubercles not extending more than half-way down declivity. 



I am indebted, for my specimen, to Mr. H. J. Carter, who cap- 

 tured it crawling along a path in King's Park, Perth. 



Chriotyphus tibialis, n.sp. 



^. Elongate, ovate, small. Black; densely clothed with dull 

 golden-brown subpubescence, feebly trivittate on prothorax and 

 near lateral border of elytra with lighter yellow or greyish, head 

 vfiih yellow supraorbital vittae, elytra obscurely maculate with 

 brown ; beneath with greyish-yellow clothing at sides of basal seg- 

 ments and covering the greater parts of the last three segments, 

 irrorate with small, dark spots; median vitta brownish. 



Head strongly convex, with a feeble, longitudinal impression 

 and rather obscure rugose punctures in front near base of rostrum. 

 Rostrum as in the genus. Prothorax (3 x 3-5 mm.) rounded on 

 sides, with feeble ocular lobes; disc with a narrow, subapical con- 

 striction; regularly set with moderately small, round granules, the 

 apices feebly flattened and crateriform, each bearing a moderately
