rado (W. Barnes), besides an eastern distribution from Maine 

 to Texas. 



The form basiflava Packard is referable here. It differs by 

 the yellow infusion at the base of fore wings. It is the domi- 

 nant form in the southern part of the range of the species, my 

 specimens being from New York to Florida and Texas. The 

 larva agrees with Abbot's figure of achatina, and it may be 

 that that name should be associated here rather than where I 

 have attempted to place it. However the base of the wing is 

 distinctly infiltrated with yellow, not white as in Abbot's fig- 

 ure of achatina, so I let the names stand as above until fuller 

 material is forthcoming from Georgia. Also, the subterminal 

 markings forbid this reference. 



Olene atrivenosa Palm. 



This form is really entirely distinct. Mr. Palm kindly al- 

 lowed me to examine the male and female specimens in his 

 collection. The published figure does not do justice to the 

 black longitudinal lines, which are very distinct. There is no 

 white on the wings. 



FEEDING ON CONIFERS. 



These forms are distinguishable in a general way from those 

 feeding on deciduous trees by the more mottled character of 

 the maculation and the predominance of brown in the ground- 

 color. The species are in general smaller and there is less 

 difference in size between the sexes. 



Olene manto Strecker. 



I have recently examined the unique male type now in the 

 Field Columbian Museum in Chicago. It is closely allied to 

 the following form, but less suffused with brown. 



Olene interposita, new variety. 



Similar \Q manto Streck., but more uniformly brown. Fore 

 wing suffused with brown, the lines black, distinct, irregularly 

 crenulate and rather broad. A white cloud in the discal area, 

 defining the brown-filled oblique reniform; subterminal line 

 pale, waved, followed by a grayer terminal area. In the fe- 

 male the median space is largely gray. 



One male, one female, Tryon, North Carolina, August 1, 

 1903 (W. F. Fiske). 



Type: No. 13465, U. S. National Museum. 



In manto the terminal spece is nearly clear grav to the 

 margin and a narrow, wavy white line crosses the basal space.
