Two females from Bellary District, Beeravalli, and Hada- 
galli, 8. India, in I. EK. E. Coll.

as follows :— 
“‘ Ashy grey. Abdomen with a large black spot on each 
segment. Legs black. Wings yellow, the first posterior 
cell closed. (PI. ix. fig. 3.) 
“ Length, ¢, 18 mm. 
“Face, moutache, aud beard white. Palpi with white hairs. 
Forehead and hind part of head with yellow hairs. Antenne 
with the third joint somewhat elongated. Eyes violet. 
“ From the coast of Malabar.” 
A black species with narrow pale segmentations on the 
white-haired abdomen. Scutellumwith white hairs. Ovipositor

A female from Berhampur, India, allied to this species

posterior cell is only narrowed at the end, where it reaches 
the border—this latter point agrees with the description of 
Promachus rufoungulatus, Macq., but the author makes no 
mention of the pale-coloured tibie.
