several times found its larva on birch and elm; Sphinx kal- 
miae has been taken here only three times to my knowledge, 
and only once have I ever found its larva. The extreme rar- 
ity of franckit would seem to indicate hybridism, unless it be 
a rare “sport,” or possibly it is a mutant. Without any real 
proof, I must confess that I believe in the specific validity of 
Sphinx francki. 
A Third Collection of Mallophaga from Alaskan 
Birds. 
By V. L. KELLocc and W. M. Mann, Stanford University, 
California. 
In 1900 a small collection of Mallophaga, collected by Mr. 
FE. A. Mcllhenny from birds shot by him at Pt. Barrow, Alas- 
ka, was described by Kellogg and Kuwana (Proc. Acad. Nat. 
Sci. Phil. v. 23, pp. 151-159, Pl. VII, 1900). Five new Mal- 
lophagan species were described and fourteen old species rec- 
ognized in this paper. In a paper of 1902 on “Mallophaga 
from Birds of the Pacific Coast of North America” (Jour. N. 
Y. Entomological Soc. v. 10, pp. 20-28, Pl. III, 1902) Kellogg 
and Chapman recognized twelve known Mallophagan species 
from birds from Kodiak Island, Alaska, and described one new 
species from the same place. The present small collection of 
Mallophaga is composed of specimens taken from birds shot 
by the well known ornithologist, R. C. McGregor, at Norton 
Sound, Alaska, in 1900. The birds were determined by Mr. 
McGregor and the parasites were taken from the fresh host 
specimens. Fifteen host species are included in the_list and 
seventeen parasite species, of which two are herewith de- 
scribed as new. In addition one new variety is recognized. 
Docophorus communis Nitzsch. 
Two specimens from Melospiza cinerea, Amaknak Is., Un- 
alaska; four specimens from Perisorius canadensis fuscifrons, 
Norton Sound. 
Docophorus cursor Nitzsch. 
Two specimens from Surnia ululu caparoch, Norton Sound.
