bristles on the lejjs stout, reddisli-yellow, an 1 miinerous, 

 except on the tarsi, li'iiiys clear, jjfrey at apex and in the 

 middle of the cells, veins brown, small transverse vein beyond 

 the middle of the discal cell, the posterior branch of cubital

Femtile identical. Tliorax with liairs on posterior part 

 chiefly yellow. Ahdumeu with the orange-yellow hairs not 

 quite so thick on the apical s'^gnients. Ovipositor small, 

 black, similar to those of the typical species of the genus.

 with some of the transverse veins clouded as in the male. 



This sj)ccics somewhat resembles Mar/iiinus pa//ipes^s\). n., 

 but the genitalia arc diflcrent and its greater pubescence 

 distinguishes it from this and any other species of Machimus ; 

 the abdomen is also devoid of bri.stles. It might possibly 

 require to be placed in a new genus.
