TIab. — Queensland: Toowoomba (Blackburn's collection). 

 Type, I. 2717. 



A rather narrow densely-clothed species, in general 

 appearance something like ammopkilus, but with very different 

 antennae and front coxae rather widely separated. The elytral 

 setae are in quite regular rows. 



There are three specimens in the Museum, one of which 

 has the basal segment of abdomen rather more convex than 

 the others, so that it is probably a female. 



Mandalotus rufimanus, n. sp. 



d (1). Black, antennae and tarsi reddish. Densely 

 clothed with muddy-brown obscurely variegated scales, 

 thickly interspersed with setae. 



Rostrum with carina distinct throughout. Prothorax 

 with numerous partially concealed granules. Elytra oblong- 

 cordate ; with rows of fairly large punctures, appearing small 

 before abrasion; interstices evenly convex. Basal segment of 

 abdomen flat across middle. Front coxa, widely separated, 

 the dividing line between them more than half the width of a 

 coxa, front tibiae moderately curved about apex. Length, 

 3-3 \ mm. 



Hab. — South Australia: Adelaide, obtained by means 

 of a sweep-net at night from lucerne (A. M. Lea). Type, 

 I. 2718. 



The four specimens before me appear to be all males. 



POLYPHRADES INSIGNIPENNIS, 11. Sp. 



(3 . Black. Densely clothed with brownish-grey scales, 

 sometimes with a vague golden gloss; in addition with 

 numerous short and mostly depressed setae, more distinct on 

 suture on posterior declivity than elsewhere. 



Head with narrow, longitudinal impressions, vaguely 

 traceable through clothing; separated from rostrum by a dis- 

 tinct transverse impression. Rostrum with punctures con- 

 cealed, except on apical triangle, where they are small. 

 Antennae stout. Prothorax moderately transverse, sides 

 strongly rounded; with dense, depressed granules. Elytra at 

 base the width of base of prothorax, sides obliquely and 

 rather strongly increasing in width to near middle, then 

 strongly arcuate to near apex, and then produced near apex; 

 with rows of fairly large punctures, becoming small pos- 

 teriorly ; third interstice conspicuously elevated at basal 

 fourth. Four front tibial denticulate on lower-surface. 

 Length ( <$ , 9), 7-8 mm. 



9 . Differs in having the prothorax less transverse,
