says one has the thorax partly red. This variety of coloration is 
not mentioned by Gravenhorst or Taschenberg (‘ Die Schlupf- 
wespen-familie Cryptides’); the latter only describes one of 
Gravenhorst’s males: this certainly agrees with Brischke’s 
description, but neither makes any mention of the pubescence on 
the abdomen, whether dense or scattered, which is unfortunate, 
as this appears to be a good specific characteristic of the female, 
and will probably be so in the male also. In Mr. Marshall’s 
collection the male Pezomachus, under the name of H. trua, 
Foerst, which in his catalogue is given as H. palpator, Gr., male, 
agrees fairly well with H. palpator, but from the shortness of the 
descriptions it is impossible to say if they really are the same 
species. I have in my collection four males, which agree very 
well with all these descriptions; they were bred from two hosts, 
two from one and two from the other, and were given to me by 
two entomologists ; although very much alike they are, I have no 
doubt, two distinct species, but either would answer to any of the 
above descriptions. Unfortunately no females were bred with 
them, or from their obscure appearance and fleetness were not 
detected. 
Associated with Mr. Marshall’s male Hemimachus trux were 
three females mounted on card, and from the writing beneath 
evidently came from Mr. J. E. Fletcher, of Worcester, and I have 
no doubt formed part of the eight females bred by that gentleman 
from Coleophora vibicella (see Ent. Mo. Mag., viii, 162). On 
examination I think Mr. Marshall must be mistaken in the 
species, or at any rate the association of the male and female is 
not satisfactory, as of the three females two belong to one species 
and the other to a very distinct one; of the two the pubescence 
on the abdomen is scattered, whereas Foerster says of P. trux 
the pubescence on the abdomen is dense; these appear to me to 
come near P. insolens, Foerst. The other specimen has the 
pubescence on the abdomen dense, but has not, as Foerster says 
P. trux has, the spiracles on the first segment of the abdomen 
projecting very much; it appears to me to come in Foerster’s 
Diy. iii., and just before P. fallax. Ihave taken this latter species 
near Norwich, and can make it agree with none of Foerster’s 
species. ‘There being two females mixed, it is imposstble to say 
to which the male belonged. 
The next species occurring in the catalogue is another
