[Packard. 
dull brick red, being very closely allied to I. rufiventris. Head 
black, with the orbits part way up broadly marked with yellow, 
forming lanceolate triangular spots with the slender apex oppo- 
site the antennae. Base and sides of labrum yellow. Head 
wholly black in 9 . Palpi brown. Antennae in $ black ; in 9 
black, with a white ring in the middle, about four joints being 
usually white. Wings smoky violaceous ; venation as in I. rufi- 
ventris, but subcostal cell (areola or second cubital cell of Ratz- 
burg) differs in the outermost of the two lower sides being two- 
thirds as long as the inner, while in I. rufiventris it is one-half as 
long. Fore-legs brown, pale brown in $ . Basal three-fourths of 
femora blackish, legs dark brown in 9 . Hind legs black, hind 
tibiae paler at base ; hind femora reddish at base. Thorax black, 
no yellow spots on the scutum as in I. rufiventris. The disk 
or central area of the propodium differs from that of 9 in 
being deeper, with square sides, broader, and with prominent, 
irregular ridges on the surface. The disc in the 9 is much 
longer and narrower than in I. rufiventris, and more coarsely 
punctured. The central raised portion of the basal ring of the 
first abdominal ring is more distinct than in I. rufiventris (99 
being compared). Abdomen a little shorter and much more 
coarsely punctured and dull red, while in most of the species it 
is highly polished and paler red. 
Length £, .67, exp. 1.05; 9, .55, exp. .94 in. 
Bred from Pyrameis Huntera. Scudder. One female also from 
Virginia [Packard]. 
Ichneumon sp. 
A Z specimen which Mr. Riley calls I. rufiventris, differs only from 
the preceding in the propodeum being less coarsely punctured, and 
in the curved line forming the hind edge of the disk being like the 
male of I. hunterae, being broader and less curved than in the 9 of 
hunterae, and the face is black, not with a lanceolate triangular spot 
on the orbit as in hunterae, while the antennae have a whitish- 
band as in the 9 hunterae. 
It is a different species from I. hunterae. It cannot be I. rufiven- 
tris as the antennae of the Z ( fide Riley) are banded with white? 
and Brulle says that the Z of rufiventris has black antennae.
