CHILO MULTIPUNCTELLUS, new species. 



Expanse, 20-24 mm. 



Head, palpi, thorax, and fore wing- white, with a very faint yellow- 

 ish tinge, palpi externally dusted with brown; abdomen more 

 strongly shaded with yellowish gray above. 



The fore wing is finely speckled with brown all over, roughly ar- 

 ranged in horizontal lines on and between the veins, not visible except 

 through a lens. Before the white cilia is a fine brown line. 



Hind wing above and below- white. Underside fore wing cinereous 

 white. 



Eleven specimens, Oracle. Arizona. June 10, E. J. Oslar: southern 

 Arizona, Poling; ITuachuca Mountains, Arizona, Poling; Chiricahua 

 Mountains, Arizona, July 4. II. G. Hubbard. 



The venation agrees with Fernald's figure of this genus in his 

 revision of the Crambidse. 



Cotype.— Cat. No. 11960, U.S.N.M., and in Author's collection. 



CHILO PURITELLUS, new species. 



Expanse, 31-35 mm. 



Head, palpi, thorax, fore wings above and hind wings above and 

 beneath white, with a faint ochreous tinge. Upper side of abdomen

One male and one female, Baboquivaria Mountains, Pima County, 

 Arizona, July 15-30; Huachuca Mountains, Arizona, both from 

 O. C. Poling. 



Type. — In Author's collection. 



This species may be a large race of multipunctellus Kearfott, 

 but I am inclined to think it is distinct. Its large size is sufficient 

 to separate it, at least until additional collecting in these regions 

 turn up a series showing intermediate size-. 



Besides the above, I have six species of Diatrosa and three of 

 Chilo undescribed in my collections, but await longer series before 

 making them known. 



" Hampson, Proc. Zool. Soe. Lond., 1895, 940. places this species under Platytes 

 Guenee (Argyria Hiibner). As I have no specimens for examination of structure, 

 I prefer to let it remain in this yenus. according to Fernald's revision.
