to 8th and a number of flies issued on the 1 5th and 1 6th. Appare ntly 

 the same form was reared by Prof. C. P. Gillette at Fort Collins, 

 Col., from Aphis gossypii. He states that this species is 

 particularly destructive to plant lice in the insectary and is not 

 uncommon out of doors, attacking different species of plant lice. 



Male. Length 1 mm. Antennae probably one-half longer than 

 the body, thickly haired, light reddish brown; 14 segments, the fifth 

 with stems two and three times their diameters respectively; terminal 

 segment having the distal enlargement subcylindric, with a length 

 four times its diameter and a long, slender, fingerlike process api- 

 cally. Palpi; first segment subquadrate, the second with a length 

 over twice its diameter, the third one-half longer, more slender, 

 the fourth as long as the third, more slender. Mesonotum dark 

 brown, shining, the submedian lines sparsely haired. Scutellum 

 pale yellowish brown, postscutellum dark brown. Abdomen a 

 variable reddish brown, the basal segments and genitalia lighter. 

 Wings; costa light brown. Halteres, yellowish transparent. Coxae 

 and base of femora yellowish, the distal portion of femora, tibiae

This species was at first credited with producing small, irregular, 

 subovate, downy galls on the shoots of muskmelon, C u c u m i s 

 m e 1 o, a deformity which unquestionably should be attributed to 

 Contarinia setigera Lintn. The midges were reared in 

 association with the above-mentioned form in August 1888 from 

 material originating at Lowell, Mass. 



Two small parasitic flies, Lysiphlebus cucurbita- 

 phidis Ashm. and Isocratus vulgaris Walk., were 

 reared from the infested melon tips and were probably parasitic 

 upon the common cucumber plant lice with which the leaves were 

 infested.
