20, 5 Cushman: Oriental and Australian Ichneumonide 569 
apparently distinct from any of the described Oriental or Aus- 
tralian species. In a key that I have constructed from the 
descriptions of all of the species from these two regions the 
females of both species run to M. fulvipennis (Cameron) and 
the males to M. volatilis (Smith). Cameron’s species, however, 
is from northern India and, moreover, is very meagerly described, 
the entire description being composed of the characters men- 
tioned in a key to five species from that locality and a few others 
mentioned later in the description of M. latiscutis (Cameron). 
Cameron’s description of the propodeal areolation of M. fulvi- 
pennis is rather obscure, but it is apparently more nearly com- 
plete than in the two Philippine species. (Cryptus) Mansa 
volatilis (Smith) from Mysol is described in the female and is 
said to have the antennez black with a pale annulus, with which 
the present males agree but not the females. The seventh 
_ Specimen is a female from Siam. It is very distinct by reason 
of its entirely black thorax and very dark wings. 
The key mentioned above with the three new species inserted 
is reproduced below. It is based very largely on color because 
many of the species, notably Smith’s and Cameron’s northern 
Indian species, are described practically only by color.
