aave been presented in some detail elsewhere and need be only 
mentioned at this time. 
Thecodiplosis dulichii Felt 
1912 Felt, E.P. N. Y. Ent. Soc. Jour., 20:241-42 
These midges were reared from the fruit of Dulichium 
arundinaceum collected by Miss Cora H. Clarke at Magnolia, 
Mass. 

Thecodiplosis cockerelli Felt 
1918 Felt, E. P. Econ. Ent. Jour., 11:381 
The one female reared from an irregular, kidney-shaped enlarge- 
ment of pine needles collected by Ivan Way in Colorado is pro- 
visionally referred to this genus. The insect is probably generally 
listributed in Colorado since it has been received from both 
Colorado Springs and Oxford. 
DENTIFIBULA Felt 
1908 Felt, E.P. N. Y. State Mus. Bul. 124, p. 389 
1910 Rubsaamen, E. H. Zeitsch. Wissenschaft. Insektenbiol., 15:284

1913 Kieffer, J. J. Gen. Insect., fasc. 152, p. 174 
The genus comprises a number of forms closely related to Con- 
tarinia and easily separated by the triarticulate palpi and the 
conspicuous triangular apical process of the basal clasp segment 
of the male. The terminal clasp segment is therefore subapical. 
The simple, strongly curved claws are about as long as the pulvilli. 
The third vein unites with costa a little before the apex of the 
wing (plate 38, figure 1, N. Y. State Mus. Bul. 124). The species 
are all small, pale yellowish forms. One was reared from As pi- 
diotus uvae and it is possible that the others are zoophagous. 
The type of the genusis Contarinia viburni Felt.

anterior legs longer than the fourth 
b Entire insect yellowish with the exception of a dark spot on the dorsal 
part of the abdomen; wing hairs curved; antennal setae rather fine,
