 The scales on the Pelororhini are so easily rubbed off, and it is 

 so seldom that specimens can be obtained which are not more or 

 less abraded that it seems almost useless to give an exact account 

 of the patterns formed by the scales on the elytra. In the present 

 species the head and prothorax are marked almost as in P. 

 argentosiis, and the scales on the elytra form a pattern similar to 

 that in the same insect. Biit the scales forming the pattern-have 

 a much less silvery tone, — in some examples they are to a con- 

 siderable extent of a saffron or fawn colour, and the pattern is 

 (in the examples before me) much less shar]>ly defined. The 

 decided tendency of the silvery scales on the elytra to run in 

 vittce seems, however, to be distinctive of argentosus and the present 

 species. Placed beside an example of P. ai-gentosus the present 

 species differs as follows, — the eyes are smaller and more widely 

 separated (I am not absolutely certain that this may not be 

 sexual), the 2nd joint of the antennal funicle is evidently shorter, 

 the rostrum is a little longer and narrower, and the lower part of 

 the front margin of the prothorax (viewed from the side) is 

 slightly convex 'in a forwai'd direction, as though tending towards 

 being an ocular lobe. The whole insect, moreover, is a little less 

 elongate and especially a little less acuminate towards the apex.
