that it is inaccurate in that the said description would exclude 
the female. The absence of a basal dash is, in this case at 
least, not a specific but a sexual characteristic. 
In addition to the above facts it may also be stated that two 
females of C. dejecta were taken in the same locality in 1906, 
which have in each case a basal dash, and that a letter from 
Mr. Wm. Beutenmiuller informs me that the only female of 
C. dejecta in the collection of the Am. Museum of Nat. Hist. 
also has a basal dash. 
The males, in the series referred to, vary in expanse from 
70 to 78 mm., with an average of 73.4 mm., with the excep- 
tion of one individual which measures only 59 mm. ‘The 
females vary from 66 to 79 mm. in expanse, with an average 
of 72.2 mm. 
There is considerable variation shown by both males and 
females of this species. Some of the males agree quite closely 
with the descriptions of Strecker and of Hulst. In a number 
of instances there is, however, a faint indication of a tendency 
toward the formation of a basal dash, and in many cases there 
is also a slight apical shading. This apical shading Strecker 
states to have been absent in the three specimens which he had 
before him. The females are much more heavily marked with 
black, as a rule, than is the case with the males, and the apical 
shading is in many cases quite pronounced. 
The most distinctive characteristic in both sexes is the very 
striking whitish area on the costal portion of the primaries 
just before the reniform. This area, which is much whiter 
than any other portion of the wing, extends from the t. a. line 
to the reniform, and is bounded below by a horizontal black 
shading, extending from the t. a. line to the point where the 
reniform and subreniform meet. ‘This whitish patch is very 
conspicuous because of its contrasting black border and, to- 
gether with the very dark reniform, affords an easy means of 
distinguishing this species from others somewhat resembling 
it in appearance. 
The above locality yielded also a noteworthy variation of 
C. gracilis Edwards, of the form showing but little suffusion 
of the primaries, in which the median band of the secondaries
