the only discrepancies being that the scutellum, although of the 

 elongate triangular form described, cannot be called " small," 

 and that the hairs on the intermediate tibiae are scarcely " long." 

 I have not been able to examine the mandibles, and therefore 

 cannot say whether they are as described. The principal 

 character of Amphiops seems to be its having four eyes — two 

 above and two below the head — -and this is the case with the 

 insects before me, as the ocular canthus is carried along the 

 exterior margin of the eyes quite widely, thus dividing each eye 

 into two parts. The extreme convexity of these insects is such 

 that (viewed from the side) the height of the elytra is as great 

 as their length.

This species looks to a casual glance as if it might very well be 



congeneric with the species I d-^scribed as Volvulus punctatus, but 



its eye structure is quite different. In respect of puncturation 



moreover it is very different especially on the elytra where the 



punctures are very much coarser. In punctatus the elytral punc 



tures are not much less fine than in Cyclonotum Mastersi, Macl. 



Tropical Australia ; Northern Territory (Dr. Bovill ; also Mr. 

 J. J. Walker).

 Differs from the preceding chiefly in respect of the elytral 

 sculpture. In the present species the whole surface of the elytra 

 is covered with comparatively close fine puncturation with which 

 coarser punctures a.re thickly intermingled, the coarser punctures 

 having a seriate arrangement (in scarcely defined striae) on both 

 the discal and lateral parts of the elytra as well as being mixed 

 with the fine punctures all over the interstices. In A. iX)australicus 

 the tine puncturation of the elytra is so fine and sparse as to need 

 looking for, and in the sutural region (especially on the front
