Rhabdophaga podagrae Felt 



1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 355 



This species produces rather long inconspicuous swellings in 

 willow, Salix, twigs, the dark brown midges appearing in early 

 spring. This gall was taken at East Schodack, N. Y. Polygnotus 

 and Eurytoma species were reared from shoots infested with larvae 

 of this midge and those of Sackenomyia packardi Felt. 

 The same insect appears to produce a fusiform gall 4 by .6 cm 

 on Salix c o r d a t a, since specimens were received from Dr A. 

 Cosens, Toronto, Can., Sept. 2, 1913.

Gall. A uniform swelling of the twig some 5 to 7 cm in length 

 and about 1 cm in diameter, irregularly channeled by orange larvae. 

 See plate 8, figure 2. 



Male. Length 3 mm. Antennae nearly as long as the body, dark 

 brown; 21 segments, the fifth with a stem about three-quarters the 

 length of the subcylindric basal enlargement, which latter has a 

 length about one-third greater than its diameter; terminal segment 

 reduced, broadly fusiform, obtuse apically. Palpi; first segment 

 subrectangular, slightly swollen distally, the second one-half longer, 

 more slender, the third one-quarter longer and more slender than 

 the second, and the fourth a little longer than the third; face fus- 

 cous, sparsely clothed with light hairs, narrowly margined posteri- 

 orly with white. Mesonotum dark brown, sparsely bordered later-
