DiAPHANOPS PARALLELUS, Sp.nOV. 



Oblongus, sat parallelus ; brunneo-niger, pilis densis (supra 

 griseo-brunneis subtus albidis) tectus ; palpis nigris ; antennarum 

 articulis basi, tibiisque, rufis ; prothorace quam basi latiori vix 

 longiori ; elytris lateraliter baud oblique impressis ; antennis 

 corporis dimidio sat brevioribus. [Long. 4, lat, 1|- lines. 



The pubescence does not differ much in colour from that of 

 D. Meyrickij — but that of the upper surface (in the example 

 before me) wants the bright, silky tinge that is displayed on the 

 latter species. The pro thorax is of similar form, but is scarcely 

 longer than its width at the base, where moreover the width is 

 scarcely greater than at the dilatation near the front. The elytra 

 differ from those of D. Meyricki in being almost parallel nearly to 

 the apex, in their greater convexity, their more rounded apices and 

 in their more even surface. The antennae are equal in length to 

 f the length of the whole body. It should be noted that the tibiae 

 are somewhat infuscate near their apex. 



The parallel form, smaller size, and differently coloured antennse 

 will distinguish this species from D. Meyricki. From the older 

 species the shortness of the antennae will distinguish it, — as in that 

 insect M. Lacordaire says that they are half as long as the whole 

 body, which I find to be their length in the specimens that I attri- 

 bute to it ; I should judge from the description too that D. 



Westermanni is a less convex insect than this and has a more 

 elongate prothorax. If I am right in my determination of D. 



Westermanni it differs from the present species also in being much 

 less parallel. 



A single specimen was taken in Western Australia by E. Mey- 

 rick, Esq. 



Lema bifasciata. Fab. 



I have received from Dr. Bovill a single specimen (taken in the 

 Northern Territory) which agrees very well with Olivier's brief
