1228 REVISION OF THE GEXUS HETERONYX, 



again as wide as long and with slightly more rounded sides^. 

 9-jointed antennae, the long scattered hairs rather thinly — in- 

 creasingly so hind ward — clothing its surface ; the absence of a 

 conspicuous red membranous border to the elytra, the much 

 darker colour of the antennae and palpi, the fine hairs on the legs 

 and underside and which form the ventral series, and the shorter 

 and more slender tarsi) scarcely differs from H. torvus, Blackb., 

 the description of which (subject to the foregoing remarks) may 

 be read as applying to it. In one example before me I find a 

 faint indication of striae on the elytra, in the other none at all ; 

 H, torvus varies in this respect. It should be noted, however, 

 that I have not seen a female example of this insect. In the 

 tabulation (Proc. L.S. N.S.W. 1888, pp. 1328, ifec.;, this species 

 would fall side by side with piceus, Blanch., from which inter 

 alia the long hairs over its upper surface may be taken as a 

 distinction.

H. PICEUS, Blanch. 



I have received from Mr. T. G. Sloane a specimen of Reteronyx 

 taken on the Blue Mountains which, with much doubt, I am 

 inclined to regard as a very peculiar example of this insect. Its 

 very diminutive size (long. 4? lines) is accompanied by a shorten- 

 ing of the hind coxae, those organs being (not much, but certainly 

 a little) smaller in proportion to the metasternum than in speci- 

 mens of 2>iceus from other localities. The append iculation of the 

 claws moreover seems to be a little nearer the apex in this example 

 than in typical piceus. The resemblance to jyiceus however is too 

 close to justify me in giving a new name on the inspection of a 

 single example. 



H. VIATOR, sp.nov. 



Minus elongatus ; postice leviter dilatatus ; rufo-ferrugineus, 

 antennis palpisque testaceis ; pilis adpressis sat brevibus sat 

 sparsim vestitus ; sat fortiter minus crebre (capite crebre rugulose)
