REPORT OF THE STATE ENTOMOLOGIST I917 10 1 



some time though the fly was not reared till recently. The work of 

 this insect is evidently widely distributed, since it has been observed 

 by State Botanist Peck at Bethlehem, N. Y., and later seen by him 

 in abundance at Keene Valley. The yellowish larvae occur near 

 the center of the affected fruit, producing a bladderlike distension, 

 further emphasized by the absence of the usual pit or stone. Prof. 

 George F. Atkinson found that the affected fruit was also infested 

 by a species of fungus, Exoascus cecidomophilus Atk. 



Gall. Enlarged, bladderlike fruit without a pit or stone and 

 inhabited by several yellowish larvae. 



Male. Length 2 mm. Antennae longer than the body, thickly 

 haired, yellowish brown; 14 segments, the fifth with stems one and 

 one-half and two times their diameters; terminal segment, the distal 

 enlargement suboval and with a short, broadly rounded process 

 apically. Palpi; the first segment rectangular, the second more 

 than twice the length of the preceding, the third a little longer and 

 more slender than the second, the fourth more slender and about 

 twice as long as the third. Face fuscous yellowish. Mesonotum 

 reddish brown, the submedian lines fuscous yellowish. Scutellum 

 pale yellowish, postscutellum reddish brown. Abdomen sparsely 

 yellow haired, yellowish brown, the segments narrowly yellowish 

 margined basally. Wings hyaline, costa yellowish brown. Halteres 

 yellowish transparent. Legs a variable fuscous yellowish, the tarsi 

 darker; claws long, stout, strongly and evenly curved, the pul villi 

 one-half longer than the claws. Genitalia; dorsal plate short, broad, 

 slightly incised, the lobes broadly rounded. Described from alco- 

 holic specimens. 



Female. Length 2.5 mm. Antennae extending to the second 

 abdominal segment, sparsely haired, light brown, yellowish basally; 

 14 segments, the fifth with a stem one-fourth the length of the cylin- 

 dric basal enlargement; terminal segment slightly produced, obtuse. 

 Palpi; the first segment short, stout, the second more than twice 

 the length of the first, the third about as long as the second, more 

 slender, the fourth one-half longer than the third, more slender. 

 Mesonotum probably dark brown, the submedian lines broad, 

 yellowish. Scutellum and postscutellum probably yellowish. The 

 abdomen bright reddish brown (Fletcher). Wings hyaline, costa 

 reddish brown. Coxae, femora and tibiae pale yellowish, tarsi light 

 brown. Ovipositor fully one-half longer than the insect, the terminal 

 lobes long, slender, broadly rounded. Type Cecid. 769.

 in florets of Agrimonia striata taken at Bath, N. Y.,
