and figures agreeing with several of the forms I have 

 here treated as distinct species. I am not sure if the 

 species I have called miliaris is truly the Panzerian 

 one which is regarded by Thomson as probably 

 the same as N. croceus, but I believe it represents

 adopted by Zaddach and Andre for one of the latter I 

 think it best to use it, and have applied it to what is 

 apparently the commonest species.

Pale greenish-yellow, a large mark on vertex, the whole of meso-
