enough so to refer the species to the genus Maricopa. When 
corrected in this respect, it falls in L&tilia, and I cannot dis- 
tinguish it from Ragonot's species, to judge from his descrip- 
tion.

Pempelia albipennella Hulst, Ent. Amer., in, p. 133, 1887. 
Staudingeria albipennella Ragonot, Rom. Mem., vin, p. 136, 1901.

Staudingeria olivacella Dyar, Proc. Ent. Soc., Wash., vi, p. in, 1904. 
Mr. Kearfott has put into my hands a long series of this spe- 
cies, which shows that my perluteella and olivacella are but the 
extremes of variation of one form. The names may be used to 
designate the varieties. 
./ Heterographis morrisonella Ragonot. 
I have before me a series of 50 specimens of this species, most 
of them from Mr. Kearfott's collection. I can match Ragonot's 
figures of coloradensis and morrisonella, but there is nothing that 
would fit the form olbiella Hulst, which is said to have ' ' all the 
wing washed with vinous red." Now I have a 9 specimen 
identified by Dr. Hulst as olbiella, which is entirely washed 
with vinous red; but it is Staudingeria albipennella, not Heter- 
ographis morrisonella. I am aware that Dr. Hulst' s determina- 
tions are not generally reliable and that his description of olbi- 
ella covers ochraceous as well as brown forms ; therefore, I would 
refer olbiella as a synonym to morrisonella, not as a variety. 
The name morrisonella will stand for the dark form and colora- 
densis for the pale one. The two are not sharply separated, but 
intergrade. 
Homoeosoma oslarellurrr, new species. 
Fore wing dark blackish, relieved by a scattering of gray scales on the 
costal portion, epecially at base of costa. Lines wanting, the outer shad- 
owed in gray scales; discal dots black, small, obscure. Hind wing grayish, 
subpellucid, lighter towards the inner margin ; fringe pale. Expanse 1 7-2 2 
mm. 
Eleven specimens, Chimney Gulch, Golden, Colorado (E. J. 
Oslar) ; five of the specimens are in Mr. Kearfott's collection. 
Type. No. 8185, U. S. National Museum. 
Nearly allied to H. electellum Hulst, but much darker and 
with obsolete lines. 
. / Homoeosoma striatellum, new species. 
Pale gray, veins all lined with black, lines nearly obsolete. The light 
gray of the ground color is dusted with blackish; a distinct black line along 
subcostal and median veins, the veins outwardly more or less distinctly
