Genitalia (fig. 57) with signum a trifle smaller than that of any 

 other Tosemiiia, otherwise not specifically distinguished. 



Larvae "dark, dull blue, and solitary or gregarious in habit" 

 (Dodd). 



Type. — In Rutgers College collection. 



Type locality. — Blanco County, Tex. 



Food plants. — Echinocereus viridiflorus Engelmann, E. polyacan- 

 thus Engelmann, and Coryphantha aggregata (Engelmann). 



Distribution. — United States: Colorado^ Denver (July) and one 

 specimen with only the State designation; Nevada^ Clark County 

 (Apr., May) ; Calif o'tmia, San Bernardino County (Apr.), Providence 

 Mountains (May), one specimen with only State designation (Apr.) ; 

 Arizona, Yavapai County, Ajo (Pima County, March), Baboquivari 

 Mountains (May), White Mountains (June), Pinal Mountains 

 (Apr.), Quijotoa Mountains (June), Santa Rita Mountains (June), 

 Sells P. O. (Pima County, May), "en route from Dewey to Salome" 

 (Apr.), Mojave County (May), Roosevelt (June), Phoenix (March, 

 Apr.), Redington, no locality except the state (2 specimens reared 

 from Coi'yphantha aggregata., June) ; New Mexico (March) ; Texas 

 (no specific locality, one specimen reared from Echinocereus viridi- 

 fiorus, Apr.). 



Seventy-six specimens examined. 



Remarks. — This species bears a superficial resemblance to Rumatha 

 hihinda (Dyar) and might easily be confused witli that species. On 

 other than structural characters it is most readily distinguished by 

 the distinct black scaling outlining the veins and rather strongly con- 

 trasted against the white dusting on the costal half of the fore wing. 



I follow Barnes and McDunnough (1916) and Hulst (1890) in 

 reference to the type locality. According to the former the type is 

 from Texas and not Colorado as given by Hulst in 1888.
