 terior coxae and trochanters ; petiole rather longer than 

 the post-petiole, about one-third the width ; the sides of 

 the post-petiole almost parallel, marginated at the

 regularly dispersed pubescence ; 2nd segment slightly

 and the face black or blackish. 



This fine species was taken by Dr. Capron in the 

 neighbourhood of Shere, and to him I am indebted for 

 a specimen. It comes in Section I. C. a. ** of Holm- 

 gren's divisions of Mesochorus.
