A NEW SPECIES OF TELENOMUS PARASITIC ON THE 
EGGS OF TUSSOCK MOTHS. 
By Cuarwes T. Brvues.? 
The present species belonging to the very extensive Scelionid 
genus Telenomus was reared from eggs of two species of Tussock 
moths and sent to me by Mr. W. F. Fiske, in charge of the Gypsy 
Moth parasitological laboratory of the U. S. Bureau of Entomology 
at Melrose Highlands, Mass. It appears to be new to science and 
as Mr. Fiske wishes to refer to it in a forthcoming publication, he 
has requested me to prepare the description which is herewith 
presented. 
Telenomus fiskei sp. nov. 
?Length 1 mm. Shining black; the legs, except cox, honey yellow or 
brownish-yellow, the femora piceous or fuscous; wings hyaline. Head 
nearly four times as wide as thick antero-posteriorly. Ocelli in a curved 
line, the lateral ones removed from the eye margin by less than their own 
diameter. Head margined behind the eyes, the raised margin extending 
over the vertex as a distinct carina for about a third the distance toward 
the median line; behind this the occiput is margined, more distinctly so 
on the sides. Vertex shagreened; the front below the ocelli smooth, and 
highly polished, but with a shagreened sculpture on the sides below. An- 
tenne black; 10-jointed, with a 5-jointed club. Scape brownish at base 
and apex, reaching nearly to the vertex; pedicel brownish at the tip, fully 
twice as long as thick at the apex; first flagellar joint fully as long as the 
pedicel and as thick; second shorter, two thirds as long, the fourth broader 
and more rounded; first four club-joints large, quadrate, equal; last a 
trifle longer, and sharply conically pointed. Thorax as wide as long, very 
convex in front, shining above, but thinly covered with a white pubescence. 
No trace of parapsidal furrows. Mesonotum and scutellum very faintly 
shagreened. Postscutellum finely rugulose-punctate. Abdomen _ short, 
sessile, about as long as the thorax, first segment coarsely longitudinally 
striated, four times as broad as long at the middle; longer at the sides, 
and with a large fovea at each anterior angle; second segment with a 
basal series of longitudinal striz as long as those on the first segment 
medially, but becoming shorter toward the sides; about one third longer 
than wide; following segments each very short, together scarcely over one
