Long. 11 mm. 
This species is allied to P. fuscipennis, Sm., from which 
it differs as follows: — ^The clypeus is yellow, the 
anterior margin of the thorax is not testaceous, the 
tegulse are paler, the punctuation throughout is finer 
and closer (especially so on the metathorax, which is 
a little rugose only in front and on the hind body). 
The basal joint of the antennae is much more strongly 
compressed, being on its fiat face as wide as long, 
'and has its front side more strongly rounded than 
the hinder side. 
I have seen only a single S of this insect, which occurred 
in September on Haleakala, Maui at an elevation of 
about 5000 feet.

The original description of this insect was founded, I 
believe, on a single individual of each sex, the $ 
being an unusually brightly coloured one. At a 
subsequent period I met with the species plentifully, 
and the examination of something like a hundred 
specimens has satisfied me that it is subject to much 
variation. I think, therefore, that it will be well 
to supplement the description with a further one, 
somewhat more in detail. The distinctive characters 
seem to be as follows : — Head unusually elongate in 
both sexes, the width across and including the eyes 
being scarcely equal to the total length. The clypeus 
is abruptly truncate or even gently concave at the 
apex. In the male, the whole space below the 
antennse is yellow, and this colour is produced in a
