﻿•26 NINTH ANNUAL EEPORT 



When at last the moiety does hatch out, it is considered by inexpe- 

 rienced persons as a distinct second brood. There is also very fre- 

 quently a great variation, probably from similar causes, in the time at 

 which the same batch of pupas burst forth into the perfect winged 

 state. For example, out of a lot of 31 cocoons, of the second brood 

 of the Imported Currant-worm Fly, all received by us at the same 

 time from Dr. Wm. M. Smith of Manlius, N. Y., most ot the flies came 

 out between June 26th and July 11th, but a few did not appear till 

 towards the latter end of July and one lingered on till August 13th." 



As I have captured the female fly in East St. Louis, and as worms 

 which, from- the description, could not well belong to any other spe- 

 cies, were noticed by Mr. T. W. Guy, of Sulphur Springs, on bis goose- 

 berry bushes in 1870, there can be little doubt that the species occurs 

 with us, as it is generally distributed throughout the country. Mr. L. 

 D. Votaw of Eureka, has also reported to me the occurrence on his 

 place of a "small green and unspotted worm" on his currant bushes. 



REMEDIES. 



The same as for the preceeding species. 



DESCRIPTIVE. ^ 



1 reproduce, from the Practical Entomologist (Vol. I, p. 123), Mr. 

 Walsh's original descriptions, drawn up from many specimens. 



Pristiphora grossulari^— /»i?naz!Mre larva. — Length not quite reaching \ inch. 

 Body pale green, with a rather darker dorsal line, and a lateral yellowish line above 

 the spiracles, the space below which line is paler than the back. Anal plate and pro- 

 legs immaculate. Head black, not hairy. Legs brown, except the sutures. 



The mature, larva measures i inch in length, and differs in the head being pale 

 green, with a lateral brown-black stripe commencing at the eye-spot, and more or less 

 distinctly confluent with the other one on the top of the head, where it is also more or 

 less confluent with a large central brown-black spot on the face. The legs are also 

 green, with a small dark spot at the exterior base of each, and a similar spot or dot 

 before the base of the Iront legs. 



/wiayo—?— Body shining black, with fine, rather sparse punctures. Head with 

 the entire mouth, except the anterior edge of the labrum and the tip of the mandibles, 

 dull luteous. Labrum transverse and very pilose. Clypeus short, squarely truncate, 

 immaculate. Antennae § as long as the body, joint 3 three and a half times as long as 

 wide, joint 4 fully \ shorter than joint 3, 5—9 very slowly shorter and shorter ; brown- 

 black above, beneath dull luteous, except joints 1 and 2, which are black, tipped below 

 with luteous. Thorax with the wing-scales honey-yellow and the cenchri whitish. 

 Abdomen with the basal membrane whitish; ovipositor honey-yellow, its sheaths 

 black. Legs honey-yellow, or sometimes pale luteous, with the six tarsal tips of the 

 tibi.-B and of the tarsal joints 1—4, pale dusky. Wings subhyaline, tinged with dusky; 

 veins black; costa honey-yellow ; stigma dusky, edged all round with honey-yellow, 

 especially below. In a single wing of two females only out of forty-nine, the first sub- 

 marginal cross-vein, which in this genus is normally absent, is quite distinct : and in a
