One specimen, Fort Collins, Colorado (C. P. Gillette). 

 Tvpe. No. 7850, U. S. National Museum. 



Homceosoma reliquellum, n. sp. 



Smooth, obscure cinereous, thickly dusted with white on costal half. 

 Lines obsolete, the inner represented by three black dots, the upper and 

 lower of which are very small, the middle one more outwardly placed; 

 outer line indicated by an outward blackish shade, curved, regular and 

 even. Discal dots black, joined into a large spot in the male, narrowly 

 separated in the female. Hind wings whitish, gray tinted along costa and 

 outer edge. Expanse 15-16 mm. 



One d% one 9, Center Harbor, New Hampshire, July 19, 1902 

 (H. G. Dyar). 



Type. No. 7851, U. S. National Museum. 



Nearly allied to Homceosoma mucidellum Rag. but smaller, 

 smoother cinereous, the outer line very vague and slightly curved, 

 discal dots approximated or fused. I have mticidellum from 

 Texas, Colorado (G. P. Gillette), Kaslo, British Columbia (Dyar 

 and Caudell), Pullman, Washington (C. V. Piper), and Los An 

 geles, California (A- Koebele). The specimens vary much in size, 

 but not in the characteristic markings. 



Tacoma Hulst. 



In his original description, Hulst says, "cT antenna simple," 

 but changes this later, giving the c? a tuft of scales in the bend of 

 antennae. The genus would, therefore, fall as a synonym of 

 Ncphopteryx Hiibner, as Ragonot shrewdly suspected ;* but I 

 think the section of Nephopteryx, with veins 4 and 5 of fore 

 wings actually stalked (not approximate only), may properly be 

 recognized as of generic value, under the name Tacoma. It 

 will contain, of North American species, feriella Hulst, snb- 

 tinctella Rag., and the following: 



Tacoma nyssaecolella, n. sp. 



Dark lilaceous gray ; inner line rather oblique, pale gray, angled slightly 

 centrally, preceded on inner margin by a subquadrate brown-black patch, 

 followed outwardly by a triangular black patch on costa, joined to a nar 

 row black line below. Discal dots joined, biack ; a huge, diffuse, brown- 

 black spot below, touching inner margin and outer line. Outer line pale, 

 slightly excurved in the middle, very obscurely dentate, edged faintly and 

 narrowly with black. Terminal line black; fringe gray. Hind wings 

 pale fuscous. Expanse 16 mm. 



One 6% bred from Nyssa multiflora* issued August 14, 1894. 

 " Collected near Bladensburg Road, D. C., in a tightly folded leaf.
