348 THE CANADIAN ENTOMOLOGIST. 



overlaid with a lighter shade of cupreous-fuscous, forming a continuous 

 terminal line, but inward interrupted by white spots between the veins. 

 Cilia white at base, through which runs a fine dark line, outwardly lighter 

 shining fuscous. 



Hind wing whitish-yellow, cilia white, with faint median line ; under 

 side fore wing shining light fuscous, slightly darker over, veins ; hind wing 

 yellowish-gray, slightly darker over veins 7 and 8. 



Variation : Description is from average specimens ; the amount of 

 dark scaling is not uniform, in some specimens the dusting is much 

 heavier, nearly filling the interspaces, especially beyond and below cell, 

 in others the dark scales are absent, except on the veins, but in all the 

 pattern is maintained as per the description. 



Described from 8 males and 8 females bred from larvse on a Japanese 

 species of hemlock, Tsuga sieboldi, at a nursery in New Jersey ; issued 

 May 7 to 23. A pair of co-types deposited in U. S. Natl. Mus., N. J. 

 Agric. Exp, Sta., Meyrick collection, the balance in Kearfott collection. 

 Larva full-grown, from alcoholic specimen. 



Fourteen mm. long, 2.5 mm. diam. at ist abdominal segment. 

 Cylindrical, slightly tapering from ist abd. to anal segment. Head 

 blackish-brown, flattened in front, rather square on top ; clypeus triangu- 

 lar, reaching only halfway to vertex ; epistoma paler; antenna concolor- 

 ous. Prothoracic shield large, concolorous with head, bisected by paler 

 dorsal line, two tubercular plates below large and brown. Body cream- 

 white, speckled with pink, the pink specks are in a double dorsal line, a 

 subdorsal line, a subspiracular line and a line above the feet, also a less 

 distirctly defined ventral line. The subdorsal line is darker and better 

 defined than the others. Tubercles prominent, pinkish-brown. Setae 

 moderate, pale. Anal shield large, yellow, speckled lightly with pale 

 brown. Thoracic feel blackish-brown, annulated with whitish ; abdominal 

 feet moderate, normal, the crochets in complete ellipse. 



Pupa, 8x2 mm., slightly flattened, light brown, darker on dorsum. 

 Frontal shield similar to Tortricid pupa. Cremaster broad laterally, with 

 two outer and two middle very short hooks. 



Examples of this larvae were submitted to Prof. W. T. M. Forbes, who 

 has written description which will follow. In a letter, Mr. Forbes states : 

 "The caterpillar shows some curious likenesses to Endrosii lacteella, 

 such as the form of the front and surrounding parts. There seems to be 

 also a suggestion of the curious slit-like marks on the labium. On the other 

 hand, the set?e on the prolegs are unique, so far as I have seen, and so is 

 the double ring of tubercle iii. Can it use setfe iii in travelling, and so need 

 a more complex joint for them than other caterpillars, hjive ?" 



Mailed October 7th, 1910.
