femora. The notch near apex of each of the four hind tibiae 

 oi the male is very strong, but from some directions practi- 

 cally invisible. 



Mandalotus rudis, n. sp. 



d" . Black, in places obscurely diluted with red ; an- 

 tennae dull-red, scape darker ; tarsi reddish-castaneous. 

 Densely clothed with muddy-brown or sooty scales, inter- 

 spersed with very stout depressed setae. 



RostTUTn without a visible carina. Scape for the genus 

 rather long and thin. Prothorax large, feebly transverse, 

 sides strongly and evenly rounded, apex distinctly narrower 

 than base ; median line traceable before abrasion ; with nume- 

 rous, rather large, round, somewhat flattened granules, more 

 or less traceable before abrasion. Elytra scarcely conjointly 

 arcuate at base ; shoulders projecting, with a rather feeble 

 subhumeral tubercle, disc uneven and obsoletely tuberculate, 

 especially about summit of posterior declivity ; with rows of 

 large, normally-concealed punctures. Mesosternum with a 

 wide, feebly conical intercoxal process. Metasternum and 

 Ijasal segment of abdomen feebly conjointly concave in mid- 

 dle. Front coxce widely separated ; hind tibiae with an 

 inner row of granules, invisible from most directions. 

 Length, 6 mm. 



Hah. — Queensland: Cairns (E. Allen). 



In the table given by me this species would be placed 

 next to crudus, which in fact it very strongly resembles, but 

 it differs in having the prothorax larger, with more conspicu- 

 ous granules, the front coxae more widely separated (the dis- 

 tance between them is almost equal to that separating the 

 middle tibiae, instead of less than half as in a-udus), and the 

 mesosternal process less acute, although of about the same 

 length. The abdomen also is without the conspicuous gran- 

 ules of cnidtis. 



The setae are unusually stout, and most of them are quite 

 flat amongst the scales. 



Mandalotus armipectus, n. sp. 

 c? . Colour as described in preceding species. Densely 

 clothed with muddy-grey scales, sometimes variegated with 

 sooty. With moderately stout semi-erect setae. 



nostrum with a narrow carina. Scape feebly curved, 

 apex rather suddenly thickened. Prothorax moderately 

 transverse, sides strongly rounded, apex much narrower than 

 liase, which is almost truncate ; median line distinct ; surface 

 uneven. Elytra trisinuate at base, subhumeral projection 

 distinct ; with rows of large, partially-concealed punctures ; 

 alternate interstices moderately raised. Prosternum with a
