OF WASHINGTON. 31 
I cannot see more than one species in all this. I have a long 
series of specimens from Texas and Arizona. The venation is 
variable. 
Tetralopha humerella Ragonot. 
Tetralopha humerella Ragonot, Bull. Soc. Ent. France, p. cli, 1888. 
Pococera humerella Hampson, Trans. Ent. Soc. Lond., p. 458, 1896. 
Tetralopha formosella Hulst, Can. Ent., xxxn, p. 169, 1900. 
Dr. Hulst gave me this synonymy and it should have been 
incorporated in Bulletin 52 of the U. S. National Museum. The 
larva feeds in the pods of Gleditschia triacanthos; U. S. Dept. 
Agriculture, Bureau of Entomology, Nos. 455 and 5120. 
Tetralopha militella Zeller. 
Tetralopha militella Zeller, Isis von Oken, p. 880, 1848. 
Lanthaphe asperatella Clemens, Proc. Acad. Nat. Sci. Phila., p. 207, 1860. 
Benta expandens Walker, Cat. Brit. Mus., xxvn, p. 112, 1863. 
Toripalpus taleolalis Hulst, Trans. Am. Ent. Soc., xm, p. 160, 1886. 
Tetralopha fuscolotella Ragonot, Bull. Soc. Ent. France, p. cli, 1888. 
Tioga aplastella Hulst, Ent. Amer., iv, p. 113, 1888. 
In Bulletin 52, U. S. National Museum this species is repre- 
sented by three specific names in as many genera. The sup- 
posed generic differences may be at once discarded, since they 
are founded on the variable venation. The amount of white 
shading on the fore wings is likewise very variable, and it is this, 
I suppose, which has further influenced the continued separation 
of -the forms. Under the specific name melanogrammos Zell., 
Dr. Hulst gives the variety diluculella Grt., with talleolalis 
Hulst as a synonym. This is wrong, I believe, as diluculella 
Grt. is robustella Zell., the pine feeder, as given by Sir Geo. F. 
Hampson. 1 But Hampson continues talleolalis Hulst as a 
synonym to diluculella, Grt., which is wrong again, as this form 
should be attached to militella Zell. Hulst 's type was one 9 
from Colorado, and I would use the name talleolalis to designate 
the western race of militella, which is larger, more diffusely 
marked, the lines shaded and broadened. I have it from 
Aweme, Manitoba (Criddle), Winnipeg, Manitoba (Hanham), 
Stockton, Utah (Spalding), and southern Arizona (Poling). 
The white shadings vary from extensive to absent. 
There is another form, a true variety, not a race, which I 
would designate by the name clemensalis, new variety. It has 
the thorax and base of fore wing shaded with dull ocherous. It 
was mentioned by Clemens, but not named. The variety 
occurs occasionally in eastern material. I have three before 
'Transfent. Soc. Lond., p. 457, 1896.
