examples. A triangular white spot rests upon the middle of the hinder border of the 

 wing, divided at the base by light brown, extending obliquely up and outward to the 

 middle of the wing, where it meets the metallic stripe from the first costal spot. The 

 metallic stripe from the second costal spot extends obliquely for a short distance 

 towards the anal angle, where it is joined with the one from the third costal spot, then 

 curving downward they extend as one stripe nearly across the wing, forming the 

 inner boundary of the ocellus. The metallic stripes from the two outer costal spots 

 also unite a little below the costa and extend across the wing parallel with the last, 

 formiug the outer boundary of the ocellus and, curving inward, unite with the 

 other beneath the ocellus, and just above the anal angle. The dark brown between 

 the costal spots extends down between the metallic stripes, sufl'using more or less the 

 ocher yellow of the wing. Ocellus straw-yellow, with three parallel dark-brown 

 dashes, sometimes only represented by one or more dots. The basal portion of the 

 wing forms an acute angle near the middle of the cell, and is somewhat suffused with 

 brown where it rests against the first oblique stripe and the white spot of the inner 

 border. Fringe metallic blue or purple, according to the light, with a basal dark-brown 

 line and a few white scales below the apex. 



Hind wing and abdomen above, and under side of all the wings, fuscous ; fringes 

 of hind wings a little lighter. Costal spots of the forewings reproduced beneath. 

 Expanse, female, 12™™; male, 9-10'"™. Habitat, California. Described from three 

 males and two females, one male and one female in mj' collection, the rest in the col-

122. The Sulphur-leaf Roller Moth. 

 Dichelia sulpliureana Clemens. 



This leaf-roller is common on Pinus strobi at Brunswick, Me., and 

 was also found on P. rigida the first week in August. 



August 5 it began to make a slight cocoon by drawing together the 

 leaves into a rude tube and spinning a slight cocoon between them. 

 The pupa was found between the leaves August 7th. The moth ap- 

 peared August 16 to 17. 



Says Mr. Forbes (3d Eeport Ins., Illinois): 



Professor Comstock believes this leaf-roller to be at least three-brooded, the larvte 

 of the first brood occurring in May; of the second, in June, and of the third, in 

 August. 



Larvfe collected by him May 13 pupated in part on the 19th, and emerged as moths 

 from the 19th of May to the 3d of June. Those collected June 20 pupated July 1, 

 and emerged July 5 to 14 ; and those taken August 15 pupated September 1, and 

 emerged September 1 to 16. Later larvpe were found October 21. 



In Illinois there seem also to be several broods, as indicated by the following facts 

 from our breeding-cage records, but it is not possible to fix their number or to assign 

 them limitations of time. 



Larvae collected May 17, this year, began to pupate on the 30th, and to emerge 

 June 7. Those obtained May 23 pupated June 11 to 21, and commenced to emerge 

 June 19. Others taken Juue 7 emerged June 26 to 28. Those i)upating July 6 

 emerged July 11 (Coquiliett), and those taken August 18 pupated on the 20th, and 

 completed their transformations on the 31st of the same month. Hence, without 

 actually breeding from the egg, we can only say that the insect breeds all summer, 

 and that it apparently hibernates in the larval stage as indicated by the late date of 

 Professor Comstock's larvfe mentioned above. 



It agrees well with Robinson's PI. Y., fig. 37, though dififering in 

 some respects. According to Fernald's Catalogue of Tortricidae, this
