REPORT OF THE STATE ENTOMOLOGIST I917 I29 



have been presented in some detail elsewhere and need Ije 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 D u 1 i c h i u m 

 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 

 distributed in Colorado since it has been received from both 

 Colorado Springs and Oxford. 



DENTIFIBULA Felt 



1908 Felt, E. p. N. Y. State Mus. Bui. 124, p. 389 



1910 Riibsaamen, E. H. Zeitsch. Wissenschaft. Insektenbiol., 15:284 



191 1 Felt, E. P. N. Y. Ent. Soc. Jour., 19:51 



1913 Kieffer, J. J. Gen. Insect., fasc. 152, p. 174 



The genus comprises a niunber 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 i, N. Y. State Mus. Bui. 124). The species 

 are all small, pale yellowish forms. One was reared from A s p i - 

 diotus uvae and it is possible that the others are zoophagous. 

 The type of the genus is Contarinia viburni Felt.
