Sept., 19 16.] Felt: New Western Gall Midges. 177 



species collected April 15 at Clarksville, Tenn. The galls were found 

 at the very base of the plant and at the time contained both larvse and 

 pupaj. The species is easily distinguished from other known females 

 by the greatly produced fifth antennal segment in connection with its 

 moderate size. 



Gall. — Somewhat cylindrical, fleshy-walled, monothalamous, length 4 to 5 

 mm., diameter approximately half the length. The walls become thin upon 

 maturity and rupture at the upper end, thus aiTording an opening for the 

 escape of the pupa. 



Pupa. — Length 3 to 4 mm., moderately stout, whitish, the older ones yellow- 

 ish orange with brown eyes, wings and legs ; thoracic horns rather long, nearly 

 straight, light brown. Antennae extending to the third abdominal segment, the 

 wings to the fourth and the legs to the sixth and seventh. The dorsum of the 

 abdominal segments thickly spotted with chitinous points and near the middle 

 a broad, transverse band of relatively long, stout, chitinous points. 



Female. — Length 4 mm. Antennae extending to the third abdominal seg- 

 ment, sparsely haired, light brown ; 14 segments, the fifth with a short stem 

 about one-fifth the length of the cylindrical basal enlargement, which latter 

 has a length about four times its diameter and moderately long circumfili at 

 the basal fourth, the distal third and subapically ; terminal segment somewhat 

 produced, the basal enlargement with a length four times its diameter and 

 apically a moderately long, stout, knob-like process. Palpi ; first segment sub- 

 quadrate, the second narrowly oval, the third greatly produced, with a length 

 five times its diameter. Mesonotum reddish brown. Scutellum and postscutel- 

 lum probably lighter. Abdomen yellowish orange. Wings hyaline ; halteres 

 yellowish basally, reddish fuscous apically. Coxs and legs mostly pale straw, 

 the claws strongly curved, simple, the pulvilli plainly longer than the claws. 

 Ovipositor about one-half the length of the abdomen, the terminal lobes almost 

 linear, tapering slightly distally and with a length over four times the width. 

 Color characters largely conjectural. Type Cecid. a27i8. 



Asphondylia adenostoma new species. 



The small gall midge described below was reared June 4, 191 2, by 

 Mr. P. H. Timberlake from apparently unmodified seeds of Adeno- 

 stoma fasciculatum collected in Laurel Canyon near Hollywood, Cal., 

 May 30, 1912. The seeds or achenes were unmodified externally, the 

 midge issuing through a hole in the side, the pupal exuviae being left 

 in a partly protruding position. 



Female. — Length 2 mm. Antennae extending to the second abdominal seg- 

 ment, rather thickly haired, black; 14 segments, the fifth with a length about 

 four times its diameter and with unusually heavy, somewhat flattened circum- 

 fili apically and at the basal third. On some of the basal segments there are 

 irregular anastomosings of the circumfili, suggesting the condition obtaining in
