than the body, which is mnch paler than in P. minutum Riley. 
Abdomen a little longer than the thorax, but no wider seen from 
above. Antennae of male with long hairs, those on the club, in 
some cases, as long as the club itself; in 9 they are naked; joint 
a little shorter than in T. minutum, as are the entire antennae. 
Wings and legs much as in T. minutum, but the legs are rather 
slenderer. 
This minute form may be at once distinguished from T. minu- 
tum by being about half as large, and by the much paler, naked 
antennae in 9 , and narrower abdomen. 
Length $, .01-.01^ inch; 9, .01§-.02 inch. 
Bred from Papilio Turnus, June 29-30 by S. H. Scudder. 
These two species seem, without doubt, to be closely allied to 
and congeneric with the species of Trichogramma figured by 
Prof. J. O. Westwood in his “ Descriptions of some minute 
Hymenopterous Insects. (Trans. Linnaean Soc. London, 1878. 
pi. lxxiii.) 
Fompilus. 
A species of Pompilus said to have been raised from Grapta 
interrogationis by Mr. E. Norton, is from Mr. Scudder’s collection. 
The body is rather stout, dull brown-black, with a faint viola- 
ceous tinge. Anterior edge of clypeus arcuate, being somewhat 
indented. The antennae are concolorous with the body, mod- 
erately slender. Labrum slightly indented ; mandibles with a 
faint red discoloration just before the tip. Wings smoky, giving 
off steel blue reflections, especially from the tip; third subcostal 
cell more oblong than in P. aethiops, the outer side being more 
transverse and less oblique than in P. aethiops. Thorax with fine 
long scattered hairs, though less hairy than in P. aethiops. Legs 
brown-black, slenderer than in P. aethiops, and, in fact, while 
approaching this species in the proportions of the head and 
antennae, the body and legs are slightly slenderer, and the 
species is considerably smaller. 
Length .54 inch. 
From P. luctuosus it is distinguished at once by the third sub- 
costal cell not being petiolate, and it is a little larger.
