front of the transverse splitting line, each rod being about halfway 

 between the margin and the center; the second pair occupy a similar 

 position on the fifth abdominal segment. All of these rods break 

 off readily, and some or all were wanting in nearly every specimen 

 examined, but the pores show their location. There is a marginal fringe 

 of smaller curved wax rods about 90 f^ long rising upward and then 

 curving outward. A pair of incurved hairs or setae about 57 ^ long 

 are borne at the caudal extremity. 



Vasiform orifice subtriangular, about 60 (* long by about 50 V- 

 broad, with angles rounded and sides bulging. Operculum semi- 

 circular, five-sevenths as long as broad, reaching half the length 

 of orifice, base nearly a straight line, apex broadly rounded. Lingula 

 spatulate, irregularly seven-lobed, three lobes on each side, with a 

 pair of spines or setae about 16 /* long borne at the extremity one on 

 each side of the terminal lobe. Lobes minutely and densely papillose. 



Adult. Female. Length about 1.15 mm. Wings about i mm. long 

 by .38 mm. wide. 



Male. Length about I mm. Wings about .92 mm. long and .36 mm. 

 wide. Rostrum about 210 p- long. Hind tibia .31 mm. long. Wings 

 white, immaculate, somewhat iridescent by reflected light, and covered 

 by a mealy or graular secretion of white wax. Hind tibia .37 mm. 

 long. Legs and body yellow. Eyes constricted, but not divided. 



Types. U. S. National Museum. 



Cotypcs. Collection of Connecticut Agricultural Experi- 

 ment Station, New Haven, Conn. 



Described from 2 9 s, 10 $ s, and hundreds of pupa cases. 



Habitat. First found by the writer on leaves of hazel, 

 Corylus americana at Poquonock, Windsor, Conn., in July, 

 1903. On July i8th and on August I2th, 1904, my assistant, 

 Mr. B. H. Walden, collected more material from the same 

 place, and the same species was found by the writer at West- 

 ville, August 5th, 1904, and at New Haven, August I4th, and 

 Woodbridge, August 25th, 1906, all on C. americana. Mr. 

 Walden collected it at Scotland, Conn., August ist, 1904, on 

 both C. americana and C. rostrata. 



A few scattered specimens on the common high bush black- 

 berry, Rnbus nigrobaccns. Bailey, growing near the hazel at 

 Poquonock (Aug. 12, 1904,) appear to be this species. 



In some cases the larvae and pupa cases were abundant, forty 

 or fifty occurring on a single leaf. Many of those at Poquo- 

 nock had been attacked by a coccinellid larva Delphastus pu-
