presented a peculiar appearance at that time, since many of 

 them were margined on the upper surface with a more or less linear 

 series of equidistant, brownish elevations which, upon examination,, 

 proved to be the tips of the puparia. The larvae evidently live in 

 communal mines and, when full-grown, cut a slitlike orifice and 

 transform so as to leave the brownish bispinose apex of the puparia 

 protruding from the orifice. A series of these presents an unique 

 appearance. The puparium is about 2 mm. long, nearly i mm. wide, 

 rather stout, a variable reddish brown, the exposed tip being a little 

 darker. Apically there is a pair of dark brown, short, stout, 

 chitinous, recurved processes. One parasite, kindly described 

 through the courtesy of Dr L. O. Howard, by Mr J. C. Crawford 

 asSympiezus felti, was reared at the same time the flies 

 issued. 



The parent insect has been described^ by C. W. Johnson under 

 the name of A. flaviventris as follows : 



Head light yellow, occiput black; antennae yellow, aristae black. 

 Thorax light yellow, with a large black dorsal spot, which extends 

 narrowly from the cervix, expanding dorsally, with lobes above the 

 humeri and base of the wings; scutellum yellow, metatarsus black. 

 Abdomen dull light yellow, terminal segment black; halteres and 

 legs yellow. Wings grayish hyaline. Length of the larger speci- 

 men 2 mm.; the smaller one 1.5 mm. 



These specimens were taken at Niagara Falls. It has been listed 

 by Smith from New Jersey, recorded by Loew from the District of 

 Columbia and identified from the Bahamas.^ In addition this 

 species has been reared at Washington, D. C, by Coquillett^ from 

 leaf mines in a species of cultivated Philadelphus and also from the 

 common Plantain, Plantago major. 



Coquebert's Otiocerus (Otiocerus coquebertii Kirby ) . 

 The slender, yellowish or yellowish red marked insects belonging to 

 this species and resembling somewhat in general appearance Caddis 

 flies, are rather common and widely distributed, having been recorded 

 from Canada, south to Texas and, in addition, from several Eastern 

 and Middle States. The delicate adults have been taken upon a 

 variety of trees, namely hickory, oak, beech, maple and also on 

 grape. 



This attractive insect belongs to the Hemipterous family Ful- 

 goridae, noteworthy because of the large exotic lantern flies. The 

 Brazilian Laternaria phosphorea has a wing spread of
