quercina Felt and may be distinguished bv the yellowish brown 

 al)domen, the longer, more slender palpi and the form of the terminal 

 lobe of the ovipositor. 



Dasyneura eugenije, new species. 



Gall. — Light green, irregularly subglobular and with a diameter ranging 

 from 5 to 7 mm. Each gall contains a number of oval cells approximately 1.5 

 mm. in diameter. One examined March 22 contained a living pupa. 



Male. — Length 1.5 mm. Antennae longer than the body, sparsely haired, 

 Ijrownish black ; 20 segments, the fifth with a stem as long as the cylindric 

 basal enlargement, which latter has a length ^4 greater than its diameter and 

 a thick whorl of very long, slender setse ; terminal segment reduced, narrowly 

 oval, and sometimes fused with the preceding. Palpi ; first segment sub- 

 quadrate, the second with a length four times its diameter, the third a little 

 shorter, more slender, the fourth J4 longer than the third. Mesonotum 

 reddish brown. Scutellum yellowish, postscutellum yellowish brown. Abdomen 

 yellowish. Genitalia fuscous. Wings hyaline, the third vein curving ante- 

 riorly. Halteres yellowish. Coxae, femora and tibiae mostly pale straw, the 

 tarsi dark straw or brownish ; claws rather heavy, unidentate, the pulvilli as 

 long as the claws. Genitalia, dorsal plate deeply and triangularly emarginate ; 

 ventral plate deeply and roundly emarginate, the lobes slender. Harpes stout, 

 with a quadrate process near the internal distal angle ; style short. 



Female. — Length 1.75 mm. Antennae nearly as long as the body, sparsely 

 haired, dark brown ; probably 20 segments, the fifth subsessile, with a length 

 about twice its diameter and rather thick subbasal and subapical whorls of 

 long, stout setae. Ovipositor about ^ the length of the abdomen, moderately 

 stout, the terminal lobes narrowly lanceolate, with a length thrice the width. 

 Other characters practically as in the male. Type Cecid a22s8. 



This midge was reared from the deformed fruit of Eugenia bitxi- 

 folia collected at Key West, Fla., March 15, 1912, by E. A. Schwarz. 

 The adults are easily separated from their allies by the numerous 

 antennal segments. 



Youngomyia pennsylvanica, new species. 



Male. — Length 2.25 mm. Antennae ?i longer than the body, thickly 

 haired, dark brown; 14 segments, the fifth trinodose, the basal and distal stems 

 with a length J/^ and twice their diameters, respectively ; the middle constric- 

 tion deep ; circumfili stout, the loops short, not extending to the tip of the 

 segment; terminal segment, basal portion of the stem with a length 2^ times 

 its diameter, the middle and distal enlargements narrowly united, the latter 

 subcylindric, with a length nearly twice its diameter and apically a long, 

 somewhat fusiform appendage. Palpi ; first segment short, irregularly sub- 

 quadrate, the second and fourth equal, the third a little shorter. Mesonotum 

 dark brown, the submedian lines, scutellum and postscutellum fuscous yellow- 

 ish. Abdomen sparsely haired, darker. Costa dark brown. Halteres yel-
