to 8th and a number of flies issued on the 15th and i6th. 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.

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

 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

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- 

 p h i d i s 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.
