wood. He must have had some additional means of identification beside the 
original diagnosis, " Niger, nitidus, pedibus obscure piceis, aHs pallide flavescenti-

genus.

I took this insect in the Metropolitan district. It dififers from any described 
species in being sub-apterous, and in the form of the striae of the mesonotum, 
which are nearly entire, and regularly curved outwards from the basal foveas, 
instead of proceeding longitudinally towards the middle of the disc. It approaches 
nearest to flavipes, Thoms. Also found by Mr. Walker.
