both s a 1 i c i s Fitch and r i g i d a e O. S. synonyms of the Walsh 

 species. The preceding, we do not believe, can be justified by the 

 rules of priority. Torymus ostensackenii D. T. was 

 reared from this midge. 



Gall. This is an apical or subapical deformity, fusiform in shape, 

 about an inch long and tipped with a rather characteristic, slender, 

 curved beak. (Plate 10, figure 2 V Galls producing parasites only are 

 almost invariably smaller and usually vary somewhat from the 

 normal. 



Phytophaga walshii Felt 

 1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 371 (Mayetiola) 



This species was reared at Lake Michigan Beach, 111., on spongy 

 or clustered galls on dwarf willow, by Prof. James G. Needham, 

 presumably in the spring of 1906. 



Gall. This is described by Professor Needham simply as a spongy 

 or clustered gall on dwarf willow, possibly only a variety of 

 \habdophaga strobiloides Walsh. (Plate 12, figure 1).

 rounded. Head small; antennae short, tapering; breastbone biden- 

 tate, the points diverging, the shaft rudimentary. Skin coarsely 

 shagreened; posterior extremity broadly rounded. 



Male. Length 4 mm. Antennae extending to the sixth abdominal 

 segment, very thickly haired, light brown; 25-26 segments, the 

 fifth with a stem three-fourths the length of the basal enlargement, 

 which latter has a length one-half greater than its diameter; terminal 

 segment produced, slender. Palpi; first segment narrowly oval, 

 second a little broader, third one-third longer than the second, 

 slender, the fourth about as long as the third. Mesonotum reddish 

 brown. Scutellum yellowish brown, postscutellum fuscous. Ab- 

 domen pale yellowish. Wings; costa yellowish brown. Halteres 

 yellowish white, fuscous subapically. Legs a variable brown; 

 claws long, slender, the pulvilli as long as the claws. Genitalia;

 swollen basally ; dorsal plate long, deeply and triangularly emarginate, 

 ventral plate long, deeply and triangularly emarginate. Harpes 

 short, stout, truncate. 



Female. Length 5 mm. Antennae extending to the second 

 abdominal segment, sparsely haired, light brown; 26 sessile segments, 

 the fifth with a length two and one-half times its diameter; terminal 

 segment broadly fused with the preceding. Mesonotum reddish 

 brown. Scutellum yellowish brown, postscutellum fuscous. Ab- 

 domen pale yellowish. Pulvilli a little longer than the claws. 

 Ovipositor about half the length of the abdomen, the terminal
