men, the segments of which are yellowish on their hind margin; the 

 balancers or hal teres with a yellow-white knob; the wings iridescent 

 and considerably longer than the body.

 of the fly are shown: a, the wing;* b, head from in front; c, halter 

 from below; d, halter from outside ;f e, ocelli from above;/, ocelli

Its Reappearance at Franklin, N. H., in 1890. 



Mrs. W. F. Daniell reports, under date of May 12th, a great dimi- 

 nution in its numbers the present year, as the result, no doubt, of 

 the efforts made to rid themselves of the pest, in their spring appear- 

 ance in 1887, 1888, and 1889, by the persistent use of pyrethrum 

 freely applied with a powder-bellows. In addition to this, hot water 

 was also thrown into the cracks and crevices about the windows and 

 piazza where they had entered for hibernation, or for shelter during 

 the cold days of spring. 



They came from their retreats with their usual regularity this year 

 about the first of April, and in their accustomed places, in the front 

 rooms of the second story on the north side of the house and around 

 the front door; but they were promptly met with pyrethrum, which 

 killed all that were seen, and a second application was not required. 



Reappearance at Alfred Center, N. Y. 



Dr. H. C. Coon, of the Alfred University, in reply to an inquiry 

 made, writing under date of November 15, 1889, stated that the flies 

 had not been observed on the windows that they had previously occu- 

 pied, but that they had been found on some papers over canned fruit 

 in the cellar, near a north window, but in far less abundance than in 

 preceding years. These were destroyed with pyrethrum powder. 

 They were not observed during the following monjkh of April. 



The unusual locality given above for the fly, and its association 

 with canned fruits, leads us to question whether examples of the 

 pickled-fruit fly, Drosophila ampelophila Loew, might not have been 

 mistaken for the Chloropsica, as the two are of about the same size 

 and form. 



* In the description of the wing of the fly. in the Fourth Report of the Insects of New 

 York, the first vein waa inadvertently referred to as the auxiliary vein. In Ghloropsicm, 

 the auxiliary vein is wanting— it being coalescent with the first. 



t The halteres are beautiful microscopic objects, being covered with a pubescence of 

 very fine white hairs, giving them the appearance of velvet — not representable in a 

 figure.
