682 REVISION OP THE GEXUS PAROPSIS, 



prosternal structure, the middle part of the prosternum being 

 devoid of both sulcus and carinfe except in occasional examples 

 which have the sculptui-e faintly indicated in the hinder part. 

 This insect is also notable for the punctures of its elytral series 

 being placed further apart one from another than they are in 

 allied species. It is of comparatively depressed form and of very 

 pale (almost whitish) testaceous colour. In a well-marked 

 example the apical part of the antennae, the back of the head, 

 two spots on the prothorax, the seriate punctures of the elytra, 

 the humeral calli and some blotches on the elytral interstices, are 

 black. The blotches on the interstices are arranged in such 

 fashion as to fall into three curved lines (with their convexity 

 hindward), one about the middle, the second half-way between 

 the middle and the apex, the third subapical. In many examples 

 some or all of these markings are wanting. The antennae are 

 comparatively short and stout. The size is long. 2|-24 lines. 

 The haV)itat is Western Australia. From the peculiar lohitisli 

 colour of the elytra of dried specimens, I conjecture that living 

 ones are of a more or less silvery colour. 



P. SUBFASCIATA, Chp. 



This species, with its var. (1) planior and the insect that I 

 believe to be P. nofatipennis, Chp., are extremely closely allied 

 forms which I hesitate to regard as of specific value; indeed, I 

 feel fairly confident that if I am right in my identification of 

 certain specimens from Sydney (the locality cited by Chapuis) as 

 notatipennis, his two species (at any rate) are not valid, for I 

 can find no character whatever except in the markings to separate 

 Adelaide examples that are evidently siihfasciata from these 

 Sj'^dney ones, and as to the markings, each one of the two varies, 

 and that most emphatically in the direction of the other. 

 P. snhfasciata is somewhat depressed in the male, but in the 

 female rather strongly convex, that sex approximating to the 

 form of P. ohliferata and its allies. It is of testaceous or rosy 

 colour except the apical part of the antennae and some blotches 

 on the elyti'al interstices, which are blackish. The elj^tral
