June, 1914-] Felt: Descriptions of Gall Midges. • 133 



Female. — Length 2 mm. Antcnnc-e a little longer than the body, thickly 

 haired, dark brown ; fourteen segments, the fifth with a stem one-half the 

 length of the cylindric basal enlargement, which latter has a length about three 

 and one-half times its diameter and presents slight indications of three con- 

 strictions, especially in the basal flagellate segment, thus duplicating in a meas- 

 ure, the three nodosities in the flagellate antennal segments of the male. Palpi; 

 first segment irregularly oval, second broad, with a length about three times its 

 diameter, the third one-third longer than the second, slender, the fourth about 

 as long as the third, slightly dilated. Mesonotum fuscous brown. Scutellum 

 and postscutellum fuscous yellowish. Abdomen rather thickly haired, yellow- 

 ish brown. Halteres and coxre pale yellowish ; legs otherwise a nearly uni- 

 form straw ; claws stout, strongly curved, the anterior unidentate, the pulvilli 

 about half the length of the claws. Ovipositor short, stout, with a length about 

 one-fourth that of the abdomen, the terminal lobes tapering to a narrowly 

 rounded, thickly setose apex. Near the posterior ventral angles of the dorsal 

 sclerite there is a peculiar filamentous, circular, chitinous structure having a 

 diameter about one-fifth the width of the basal portion of the ovipositor. 



Described from females taken in association with the male, agree- 

 ing therewith structtirally and presenting a marked similarity in ap- 

 pearance. Cecid 1490. 



Hormomyia saturni new species. 



The midge was taken August 24, 1909, by Mr. C. P. Alexander 

 in the Adirondacks, altitude 1,540 feet. It appears to be related to 

 H. shawi Felt from which it is easily separated by the darker abdomen 

 and the distinctly longer stems of the flagellate antennal segments. 



Male. — Length 3.5 mm. Antennae probably as long as the body, thickly 

 haired, yellowish or yellowish brown ; probably fifteen segments, the fifth hav- 

 ing the stems with a length one and one-half and two and one-half times their 

 diameters, respectively, the circumfili being a little longer than in H. americana 

 Felt. Palpi ; the first segment broadly oval, the second greatly produced, 

 slender, with a length about ten times its diameter. Mesonotum a variable 

 yellowish brown, the submedian lines lighter. Scutellum reddish yellow, post- 

 scutellum a little darker. Abdomen a somewhat variable fuscous yellowish. 

 Genitalia yellowish. Halteres yellowish transparent, the coxae, femora, tibiae 

 and first tarsal segment pale yellowish, the other tarsal segments lost. Geni- 

 talia; basal clasp segment stout; terminal clasp segment rather short, stout, 

 not swollen, dorsal plate long, deeply and triangularly incised, the lobes nar- 

 rowly rounded ; ventral plate long, broad, broadly and roundly emarginate. 

 Type Cecid. 1493. 



Itonida uliginosa new species. 



This yellowish midge was taken August 21, 1909, by Mr. C. P. 

 Alexander in a bog swamp at Woodworth's Lake in the Adirondacks,
