Another species,* related to the above, the larva of which was 

 not distinguished from it, — has a similar life history. Examples 

 of this larva taken April 13 emerged June 17 and 18; while imagos 

 were taken at the electric light — much less frequently, however, 

 than the preceding species — from the 4th to the 20th of June. 



Identified by Lord Wal Bingham, as I am informed by Prof. C. H. Fernald, as C m no genes mortipen- 

 jiella, Grote. The original description (''Canadian Entomologist," iv, 137, July, 1872) seems to 

 have been made from a single bleached male, and I subjoin another showing the color variations. 



A light-l)odied, narrow-winged, pale brown species, the hind wings dusky, and the fore wings 

 epecked, spotted, and minutely barred with dark brown or black. Wing expanse varying from 35 

 mm. in the smallest male to 34 mm. in the largest female. 



In the male the general color is light wood-brown, brownish gray with a tinge of yellowish, or a 

 paler gray, the best preserved specimelis sometimes with a slight violaceous sufEusion. The strongly 

 recurved palpi, reaching to the base of the abdomen, fuscous at base, otherwise grayish brown, with 

 blackish scales, darker on the terminal segments. 



Fore wing commonly more embrowned at base of costa and towards tip, but frequently with a 

 fairly well-defined marginal paler area. The posterior and inner part of the wing usually paler than 

 the rest. The dusky markings commonly sharp, but almost indescribably variable, always showing 

 a strong tendency, however, to the formation of four or five rather conspicuous subquadrate blotches 

 along the middle'^of the wing, which sometimes fuse to form a zigzag band, as in the figure (PI. vi, 

 fig. 1). The two most persistent of these blotches are behind the middle, and at the outer end, or 

 the discal cell. The costal region is commonly more or less closely barred with black, and some- 

 times the posterior margin also, and these lines may extend across the outer third of the wing to 

 form four or live irregular transverse bands. A submarginal row of black points, sometimes quite 

 distinct, sometimes fusing to an irregular line. Fringe with two dark lines, one at the base and one 

 at the tip of the scales. 



Hind wing fuscous, with a bronzed reflection, and slightly paler outwards. Abdomen like^the 

 hind wing. Beneath, both wings are uniform fuscous, slightly bronzed, the hinder a little the paler 



The females are larger, with porrected palpi, which are light brown above, darker beneath. 

 The general color of the fore wings is a slightly reddened brown. 



Described from twenty males and three females.
