and postscutollum fuscous yellowish. Abdomen a light fuscous yellowish orange. 

 Costa fuscous straw. Ovipositor rather stout and when extended about half the 

 length of the abdomen, the terminal lobes narrowly lanceolate, with a length nearly 

 three times the width, rather thickly setose apically. Other characters about as 

 in the male. 



Reared from a narrow, clustered apical bud gall on Spiraea salicifolia 

 collected by Miss Cora H. Clarke of Magnolia, Mass. Allied to 

 P. pratensis Felt. Type C. a2074. 



Cecidomyia cerasiphila n. sp. Female. — Length 2.5 mm. Antenna? black; four- 

 teen segments, the fifth with a stem one fourth the subcylindric basal enlargement, 

 which latter has a length twice its diameter, is slightly constricted near the middle 

 and has sparse subbasal and subapical whorls of setae; terminal segment somewhat 

 produced, with a length two and one half times its diameter and tapering to an 

 obtusely rounded apex. Face pale reddish yellow. Palpi pale reddish yellow; 

 first segment irregularly subquadrate, the second stouter, with a length fully twice 

 its diameter, the third a little longer, more slender, the fourth nearly twice the length 

 of the third, greatly dilated. Mesonotum black, the submedian lines fuscous. 

 Scutellum and postscutellum fuscous yellowish. Abdomen dark red. Wings 

 hyaline, costa pale straw, the third vein uniting therewith well beyond the apex. 

 Halteres reddish orange. Legs reddish yellow; the femora near the tip, and the 

 two anterior pair of tibiae and all of the tarsi dusky; claws stout, strongly curved, 

 simple, the pulvilli longer than the claws. Ovipositor greatly produced, with a 

 length fully one half greater than the body; terminal lobes slender, with a length 

 six times their diameter, sparsely setose apically. Colors by Pergande. 



Reared by Theodore Pergande from swollen fruits of wild cherry. 

 Loaned for study by U. S. Bureau of Entomology. Type C. 879. 



Cecidomyia hopkinsi n. sp. Feviale. — Length 1.5 mm. Antenna) Ught bro'mi; 

 fourteen segments, the fifth with a stem about three fourths the length of the sub- 

 cylindric basal enlargement, wMch latter has a length fully twice its diameter, is 

 sUghtly constricted near the basal third and has rather thick subbasal and subapical 

 whorls of long, stout setae; terminal segment with a length four times its diameter, 

 tapering distally to a rounded apex. Palpi; first segment irregularly subquadrate, 

 the second with a length fully three times its diameter, rather stout, the third short, 

 more slender than the second and the fourth about as long as the third, dilated.

 spotted, there being indistinctly broken, transverse bands near the middle and at 

 the distal fourth, the spot in each near the anterior margin, approximately at the 

 middle and on the posterior margin; the third vein unites with the margin at the 

 apex of the wing. Halteres pale yellowish, slightly fuscous subapically. Legs 

 dark brown and annulate with yellowish as follows: A narrow band near the middle 

 of femora; broad subbasal and subapical bands on tibiae; narrow basal bands on 

 the first and second tarsal segments ; a broad band on the middle of the second tarsal 

 segment and narrow indistinct ones basally' on the third tarsal segment. Claws 

 rather long, slender, evenly curved, simple, the pulvilU nearly as long as the claws. 

 Ovipositor short, the terminal lobes broadly oval and sparsely setose.
