R. mariona closely resembles polygoni var. animosa in coloration and 

 size, but differs in the large orange thoracic shoulder patch of both sexes 

 and in the aforementioned clear space on the hindwing of the female. 

 Structures of the genitalia differ but slightly in the two species. R. mari- 

 ona is a root borer in perennial plants of the family Boraginaceae, so far 

 bred only once from a species of Amsbickia in Oak Creek Canyon, Coco- 

 nino County, Ariz., June-July 1936 (Engelhardt). Larval borings noted 

 in roots of Ainsinckia in Mesa Verde Park, Colo., and along the Columbia 

 River Highway, Oreg., indicate a wider distribution of the species than is 

 known at present. The type specimens were collected at Trimble and 

 Pagosa Springs and Durango, Colo., July 6-30, 1899. A number of speci- 

 mens, in poor condition, were submitted by John Woodgate from Jemez 

 Springs, N. Mex.

Female. — Antennae blue-black. Palpi orange, black at tips. Head 

 blue-black. Collar lustrous bronzy, edged with orange anteriorly. Thorax 

 metallic green and blue-black, patagia tinged with orange and an orange 

 patch beneath at the wing base. Abdomen lustrous black along the back 

 and orange at the sides ; underside of the first, second, and last segments 

 black, all other segments orange, the last segment orange above and the 

 anal tuft greenish black, orange in the middle. Legs steel blue, touched 

 with orange on the inner side and at the joints. Forewing broadly mar- 

 gined with lustrous blue-black outwardly and heavily scaled with red 

 between the veins inv/ardly ; outer transparent area barely apparent, basal 

 area very narrow ; discal mark blue-black around a rather large bright red 

 center ; a bright red mark also at the wing base. Hindwing transparent, 

 narrowly bordered with lustrous black, fringes brownish. Beneath, wings 

 slightly tinged with orange and the discal mark lacking the red center. 



Expanse: Female, 17 mm. 



Distribution. — Huachuca Mountains, 7,000 feet, Cochise County, Ariz. 



Type. — Female. Collected by Charles Schaeffer on the Brooklyn Mu- 

 seum Expedition to Arizona in 1905. In the United States National 

 Museum. 



Remarks. — The female type still remains the sole representative of the 

 species. The specimen was obtained by sweeping on meadows in the Hua- 

 chuca Mountains at an elevation of about 7,000 feet. The range of the 

 species most probably extends across the Arizona border into Mexico. 

 The type specimen is in poor condition, and inclusion of the species in the 

 genus Raniosia is provisional.
