entirely white. Posterior tibiae and inner surface of intermediate tibiae 
white. Tarsi pale grayish-fuscous, faintly annulate, with white at the 
joints. Abdomen purplish-fuscous on a white ground. Alar ex. 34 inch. 
The larva mines the leaves of the Willow (Salix longifolia) for a very 
short time, then leaving the mine, it rolls the leaves from the tip upwards, 
into various forms (usually a cone or helix of three spirals). I first found 
it in September and October, and do not know whether it can be found 
earlier ornot. It frequently leaves one roll and makes another, and when 
ready to pupate, makes a dense semi-transparent web over it, upon the 
ground, not on the leaf, as in many species. The imago emerges in the 
fall, and most probably, hybernates. 
I have bred a great many species of Ichneumonides and Chalcidiide 
parasites from the different “Micros.” Among others, the following, 
which I take to be a Zw/ophus, though I can distinguish but e/g#¢ antennal 
joints. Possibly, however, one of the three terminal joints may be com. 
posed of ¢wo or more compact joints, but they are so thickly clothed with 
blackish hairs that I can not discover it without dissection, which, as I 
have but the single specimen, I do not wish to resort to. Some allied 
genera have the terminal joint composed of three compact joints ; but that 
would make the antennae in this species Zo-jointed, whereas, in Lulophus, 
they are 9-jointed. 
The antennae are black, and the third, fourth and fifth joints each 
give off, internally from the base, a plumose branch about as long as the 
portion of the stalk beyond it. Eyes bronzy brown. Head and thorax 
bluish-green, densely punctured. Legs and tarsi white, except the pos- 
terior #biæ and femora, which are pale fuscous ; abdomen blackish, with a 
pale whitish band across the tergum near the base /w. sz inch. The 
living insect seemed to be continually expanding and shutting its antennae, 
and plumes like fans. 
Bred from larvae of Gracillaria purpuriella, and I call it Lulophus 
Gracillarie.

Palpi white, flecked with dark brown, and second and third palpal 
joints tipped with brown. Face white; antennae, vertex, thorax and 
basal third of the anterior wings iridescent, deep blood-brown, purple or 
violaceous, according to the light. Antennae faintly annulate with 
whitish, and basal third of the wing faintly flecked with whitish. Trigonal 
mark faintly outlined, its anterior margin being the posterior margin of the
