318 NOTES ON AUSTRALIAN COLEOPTERA, 



This species differs so much superficially (chiefly owing to the 

 long soft hairs with which it is clothed on the sides and beneath) 

 from the others known to me of the genus that I place it here 

 with some hesitation, but I can find no structural character on 

 which to separate it except in the evidently greater convexity of 

 the eyes, but I do not think that sufiicient. All the sculpture is 

 hidden beneath densely packed scales except the punctulate striae 

 of the elytra (the punctures in which, it should be noted, appear 

 as in others of the genus — very much smaller than the removal of 

 the scales shows them to be in reality). The ground-scales in all 

 the examples I have seen are of an ashy or grey colour, but are 

 sometimes obscurely tinged with a coppery lustre ; the white 

 scales form the following marks, none of which are particularly 

 conspicuous, viz., a wide vitta on either side of the prothorax, a 

 short vitta (sometimes much elongated) from the base of the 3rd, 

 6th, 7th, and 8th interstice on each elytron, and some spots about 

 the sides and apex of the elytra (these spots wanting in many 

 examples). The close fine puncturation of the prothorax seems 

 to be that in w'hich the scales are inserted, — the sparse somewhat 

 larger punctures seem to bear the setae. To the eye the prothorax 

 appears distinctly elongate, but measurement shows that its length 

 and width are equal ; it is nearly twice as long as the head and 

 rostrum together. The specimens which I regard as females 

 (they were taken in company with the others) are strikingly 

 shorter and narrower than what is clearly I think the other sex, 

 their elytra being quite half again as wide as the prothorax. The 

 front and intermediate (but not the hind) coxae are much less 

 widely separated than in either of the preceding two species, the 

 space between the anterior coxae being just about wide enough to 

 receive the stem of the funiculus, and being, as in the preceding, 

 very conspicuously divided in the middle by a transverse suture. 



Perhaps nearest to D. jnlipes, Pasc, (of described species), but 

 considerably larger, and differing by the presence of long pilosity, 

 fuuicle not thickened towards the apex, &c. 



S. Australia ; Port Lincoln, and also near Adelaide ; on plants 

 growing on the sea-shore.
