The yellowish brown male was reared September 4, 1907 from 
irregularly thickened and folded chokecherry, Prunus vir- 
giniana, leaves taken by L. H. Joutel at Newfoundland, N. J. 
Gall. An irregular, thickened, folded, dark-green leaf containing 
a number of larvae. The upper surfaces are apposed and the thick- 
ening extends most of the length of the leaf, nearly to its edge and 
is slightly discolored, being irregularly mottled with darker green. 
Larva. Length 3 mm. Whitish, moderately stout, head small, 
antennae rather long, stout, uniarticulate; breastbone bidentate, the 
shaft subobsolescent; skin coarsely shagreened; posterior extremity 
deeply bilobed. 
Male. Length .75 mm. Antennae twice the length of the body, 
thickly haired, yellowish brown, the basal segment yellowish; 14 
segments, the fifth with stems two and two and one-half times their 
diameters, respectively; terminal segment produced, the distal 
enlargement broadly oval, constricted apically and bearing a rather 
short, stout, conical appendage. Palpi; the first segment rather 
stout, with a length about one-half greater than its diameter, the 
second a little longer, more slender, the third as long as the second, 
more slender, the fourth one-third longer than the third and stouter; 
face yellowish. Mesonotum dark brown, the submedian lines indis- 
tinct. Scutellum bright red, postscutellum a little darker. Abdomen 
yellowish brown, reddish brown basally. Genitalia yellowish. 
Wings hyaline, costa light brown; halteres yellowish orange, luscous
