OF WASHINGTON, VOLUME XIII, 11)11. 19 



The discal region, lines, and brown ground are very similar in 

 the two forms. 



Olene montana Beutenmiiller. 



Mr. Beutenrniiller has kindly shown me his types of this 

 form. The specimens are entirely suffused with brown, with- 

 out white, except at the discal area and tornus. The larva has 

 four black pencils, a pencil accompanying the tuft of joint 12, 

 the other tufts black. The specimens were bred from larvse 

 on balsam. 



I am inclined to the view that the above three forms repre- 

 sent local races of one species, in which the tendency to brown 

 suffusion is increased with the altitude. Manto was described 

 from Stewart County, Georgia, which is in the western edge 

 of the State at a low altitude; interposita comes from Tryon, 

 North Carolina, which is at a considerable altitude in the 

 foothills; montana is from the true mountain region of North 

 Carolina. 



Olene pini, new species. 



Fore wing gray, dusted with black and lightened by white mark- 

 ings, shaded with brown in basal space and between the outer and 

 subterminal lines; a small black line at the base; median lines black, 

 distinct, crenulate, the outer angulated inward on vein 1; discal mark 

 a black reniform, open and more or less broken into two black bars, 

 lightened by white edgings; subterminal line white, waved, with a 

 white spot above tornus; terminal line black, crenulate, somewhat 

 drawn back from the margin; narrow white edgings to both the h'nes. 

 Hind wings brown-gray, with discal mark and outer narrow line more 

 or less well defined. Expanse: Male 30 mm.; female 35 mm. 



Seven males and seven females, North Saugus, Massachu- 

 setts, bred from larvae on pine by Mr. W. F. Fiske, Mr. H. 

 M. Russell, and myself (Gipsy Moth Laboratory No. 1471). 

 Also a male that I take to be the same species labeled "Corn- 

 ing's farm, Gray," that is probably from near Albany, New 

 York. This specimen has a black submedian bar. Also a 

 male and female, labeled "Sharon, August 1, 1873;- July 20, 

 1874," which are brown and faded looking and without the 

 sharp contrasts of the fresh specimens. 



Type: No. 13466, U. S. National Museum. 



The larva is red-brown or blackish gray, with many plumed 

 white tufts and lateral plumed black hairs; a pair of pencils 

 in front, a pair behind, and a single one accompanying the 

 tuft of joint 12; tufts gray, intermixed with plumed white 

 hairs.
