Another species,* related to the above, the larva of which was 
k ot distinguished from it,—has a similar life history. Examples 
f this larva taken April 33 emerged June 17 and 18; while imagos 
fere taken at the electric light—much less frequently, however, 
han the preceding species—from the 4th to the 20th of June. 
Identified by Lord Walsingham, as I am informed by Prof. C. H. Fernald, as Caznogenes mortipen- 
ella Grote. The original description (‘-Canadian Entomologist,” iv, 137, July, 1872) seems to 
ave been made from a single bleached male, and I subjoin another showing the color variations. 
A light-bodied, narrow-winged, pale brown species, the hind wings dusky, and the fore wings 
pecked? spotted, and minutely barred with dark brown or black. Wing expanse varying from 25 
lm. 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 
aler °ray, the best preserved specimens sometimes with a slight violaceous suffusion. The strongly 
scurved palpi, reaching to the base of the abdomen, fuscous at base, otherwise grayish brown, with 
lackish scales, darker on the terminal segments. 
Fore wing commonly more embrowned at base of costa and towards tip, but frequently with a 
iirly well-defined marginal paler area. The posterior and inner part of the wing usually paler than 
ae rest. The dusky markings commonly sharp, but almost indescribably variable, always showing 
9 tron°- tendency, however, to the formation of four or five rather conspicuous subquadrate blotches 
lony tSe middle"of the wing, which sometimes fuse to form a zigzag band, as in the figure (PI. vi. 
o-. 1). The two most persistent of these blotches are behind the middle, and at the outer end, of 
ae discal cell. The costal region is commonly more or less closely barred with black, and some- 
imes the posterior margin also, and these lines may extend across the outer third of the wing to 
arm four or five irregular transverse bands. A submarginal row of black points, sometimes quite 
istinct, sometimes fusing to an irregular line. Fringe with two dark lines, one at the base and one 
t the tip of the scales. 
Hind wing fuscous, with a bronzed reflection, and slightly paler outwards. Abdomen like]the 
ind 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, 
'he general color of the fore wings "is a slightly reddened brown. 
Described from twenty males and three females.
