The genus is separated from Itonida principally by the peculiar 
structures of the male genitalia. The basal clasp segment is short, 
stout and broad, while the terminal clasp segment is short, stout and 
apically with a broad, chitinized serrate margin. The dorsal and 
ventral plates are short, broad, each rather deeply and narrowly 
emarginate; style short, stout. The third vein unites with the margin 
at the apex of the wing. The palpi are quadriarticulate and the 
claws simple. Type Cecidomyia obesa Felt, C 167.

This dark carmine male was taken June 7, 1906 on hemlock, 
Tsuga canadensis, at Lake Clear, N. Y. It is most easily 
recognized by the peculiar genitalic structures. 
Male. Length 1.5; mm. Antennae as long as the body, rather 
thickly clothed with fine hairs, bright carmine; fourteen segments, 
the fifth with stems hardly as long and one-half greater than their 
diameters, respectively; distal enlargement subcylindric, with a 
length one-half greater than its diameter; circumfila distinct, the 
loops of the distal filum extending to the apex of the segment; ter- 
minal segment, distal node produced, constricted at the basal third, 
the appendage with-a length twice the average diameter of the 
stem. Palpi; the first segment short, subquadrate, the second twice 
the length of the preceding, subrectangular, the third as long as the 
second, fusiform, the fourth one-third longer, more slender, all 
sparsely clothed with coarse setae; face pale yellowish, eyes large, 
black. Mesonotum and scutellum dark carmine, postscutellum 
fuscous. Abdomen dark carmine. Wings hyaline, costa pale brown, 
subcosta uniting with the margin at the basal third, the third vein 
curving slightly and joining the margin just beyond the apex, the 
fifth vein, almost obsolete distally, uniting with the posterior margin 
at the distal third, its branch at the basal third. Halteres whitish 
transparent. Legs nearly uniform pale straw, tarsi slightly darker; 
claws rather stout, slightly curved, simple. Genitalia (pl. 20, fig. 8); 
basal clasp segment very stout, broad, obliquely truncate; terminal 
clasp segment very stout, broadly rounded, the apex with a series of
