Sprinkle the leaves with hellebore powder or Paris green mixed 

 with fifty parts of flour or plaster. Air-slaked lime or even ashes 

 are said to be good remedies. 



THE CUEEANT FLY. GOOSEBEEEY FEUIT FLY. 

 Epochra Canadensis, Loew. 

 Order Diptera: Family Trypetidae. 

 Bibliography. 



Loew — In Smith. Miss. Colls. 256. Monographs of the Diptera of 

 North America Pt. Ill, p. 235, December 1873. Original description 

 under the name Trypeta Canadensis, n. sp. from a Canadian or Maine 

 specimen. Epochra is suggested as the more proper generic name. 



The female is described, evidently from a single faded imperfect 

 specimen. Habits not stated. 



Saunders — Insects injurious to fruits, 1883, p. 352. "This insect is 

 occasionally found attacking' the fruit of both the red and the white 

 currant. In its perfect state it is a small two-winged fly, which lays 

 its eggs on the currants while they are small; the larva enters them 

 while still green, and feeds on their contents, leaving a round, black 

 scar at the point of entry. The affected currants ripen prematurely, 

 and shortly decay and drop to the ground, when on opening them, 

 there wil be found in each a small white grub, about one-third of an 

 inch long, which when mature leaves the currant and probably passes 

 the chrysalis state under the ground." The above is a full statement 

 of Saunders' remarks in Insects Injurious to Fruits, p. 352. 



Gillette, C. P. — Colorado Experiment Station, Bulletin No. 19, p. 18, 

 May 1892. Account of its attacking gooseberries in Colorado. That the 

 fly punctures the skin by a sharp ovipositor. The eggs were observed 

 under the skin. The flies noticed ovipositing. The berries soon turn 

 red and drop after being stung and the maggots remain in them for 

 some time after they fall to the ground. The flies captured and iden- 

 tified. But one brood. Gathering the fallen infested berries suggested 

 as a remedy.

Snoic, W. A.— Kans. Univ. Quar., Vol. 11, No. 3, 1894, p. 159. "One 

 male (Maine) in poor preservation apparently belongs here. The wing 

 agrees with the description; the stature of the body can hardly be 

 called "short and rather broad;" the scutellnm has four bristles.
