OF WASHINGTON. 297 



larvae were thought to be of one species. But three kinds 

 emerged in Mr. Busck's hands, the present species, Lophoderus 

 color adana Fernald* and the following species. I therefore con 

 tent myself with the record of the food plant. 



Eucosma pulsatillana, n. sp. 



Near improbana Walker and radicana Walsingham and the gray form 

 of m'sella Clerck. Fore wings moderately elongate, costa strongly arched ; 

 gray, irrorate with black. Basal space broadly dark as in nt'sella-, the out 

 wardly limiting line bowed outward a little at the middle, slightly oblique, 

 so that the space is broader on internal margin than on costa, coarsely 

 irrorate with black. A dark gray bar, limited by irregular black scales, 

 starts from the middle of the cos'a and bends outward to the middle of the 

 disk, narrowly, but sharply and squarely separated from a similar short, 

 curved bar arising from the anal angle ; a dark costal dash throws a waved, 

 irregular line obliquely to above anal angle; three costal dashes beyond 

 this, the outermost largest and reaching opposite the middle of margin; 

 a terminal black band, wide centrally; fringe gray, irrorate in black. In 

 some specimens the lower part of the basal space and the bar at the anal 

 angle are shaded with ocherous. Hind wing light silky grayish. Ex 

 panse, 15 to 17 mm. 



Twenty males and eight females bred from larva? found web 

 bing the leaves of Pulsatilla hirsutissima high on the foothills 

 at Boulder and Golden, Colorado. 



Type. No. 6768, U. S. National Museum. 



Eucosma cercocarpana, n. sp. 



Veins 3 to 5 of fore wings are converged toward a marginal incision. 

 The wings are elongate and narrow, costa convex, inner margin concave 

 before the anal angle. Markings closely as in improbana Walker, but the 

 median band is more oblique and there is a dark marking subapically. 



Dark gray, the lighter parts of fore wings with shining, slightly raised 

 scales. A large dark basal space, sharply limited outwardly and with a 

 central angle, is irrorate with black scales on a dull olivaceous brown 

 ground. Beyond the ground is cinereous, irrorated with olivaceous. An 

 oblique bar from near basal third of costa to before anal angle is cut by a 

 longitudinal black dash which causes a projection on each side, the inner 

 one nearly or quite touching the projection of the basal patch- another 

 projection from the bar on its outer side near inner margin extends nearly 

 perpendicularly upward. Beyond and above the black bar is a second 

 less evident one, situated in the upper part of an olive brown cloud sub 

 apically. A small black apical dash with olivaceous brown below on 

 fringe. A row of small, oblique, costal bars. Fringe dark gray on lower 

 two-thirds of termen. Hind wing brownish gray, darker outwardly. 

 Expanse, 15 to 18 mm.
