Ichneumon tharotis n. sp. 
One 9 allied to I. suturalis Say, but much smaller. Head a 
little shorter than in I. suturalis. Eyes much larger and more 
spherical ; vertex a little more elevated. Head and thorax more 
densely punctured than in I. suturalis, the punctures being rather 
finer on the head, and the thorax is finely shagreened and dull, 
instead of polished, with scattered irregular punctures as in 
I. suturalis. Whole body pale reddish brown; head and thorax 
a little darker than the abdomen. Antennae longer and slenderer 
than in I. suturalis, concolorous with head on the basal one-third, 
third joint a little dusky, fifth-sixth joints a little dusky, tip of 
sixth and seventh-twelfth joints white, those beyond blackish. 
Two faint dark lines along the mesoscutum ; hind edge black, 
scutellum yellow, surrounded by black, the whole metathorax 
black except the scutum, which is dull reddish. Sides and pectus 
of thorax and propodeum a little paler. Ridges enclosing the 
areoles on propodeum high and prominent, much more so than in 
I. suturalis. The whole propodeum is longer, and slopes at a less 
angle to the insertion of the abdomen than in I. suturalis. 
Sutures at insertion of coxae black, a black line running part way 
up the suture between the propodeum and the thorax proper. 
Wings clear. Venation much as in I. suturalis, but the subcostal 
cell (the smallest in the wing) differs in the outer of the two 
lower sides being one half as long as the inner, while in I. sutura- 
lis the two are of nearly the same length. Legs reddish ; coxae 
slightly yellowish ; tips of terminal tarsal joints of fore legs a 
little dusky; the whole joint a little dusky in the middle pair; 
hind pair dusky at the tip of femora, distal third of tibiae dusky, 
and tarsi brown. Pedicel of abdomen long and slender, with the 
two ridges prominent ; the expanded end of the joint is much 
narrower than in I. suturalis. Body of the abdomen oval, at the 
base larger and farther apart than in I. suturalis, suturfes faintly 
marked with blackish. 
Length .40, exp. wings .62 inch.
