apex of tegula mainly orange; disk mainly brown. Forewing: orange, 

 red brown, browai, gray bro\vn, and buff; gray-brown scales with purple 

 reflections. Hindwing : fuscous, cilia buff. Prothoracic leg : coxa and 

 femur pale orange heavily dusted with brown; tibia brown with a 

 faint subbasal orange band, another at base of epiphysis, apex orange; 

 tarsus bro\Mi, base and apex of basitarsus and apices of second and 

 fifth segments buff. Mesothoracic leg: coxa mainly pale buff, a row 

 of brown- tipped scales before apex; femur buff mottled with brown; 

 tibia brown with subbasal, medial, and apical pale buff fasciae; tarsus 

 brown, base and apex of basitarsus and apices of second and fifth 

 segments pale buff. Metathoracic leg: coxa buff and gray white with 

 some gray-brown splotches; femur buff flecked with brown, brown 

 fasciae at one-fourth and two-thirds; tibia pale brown (scale bases pale) 

 with pale buff to buff white fasciae at one-fifth, middle, and apex, 

 dorsal tuft pale buff, outer spurs pale basally, brown distally; tarsus 

 brown, base and apex of basitarsus and apices of remaining segments 

 pale buff. Abdomen: not available. Alar expanse: 13-15 mm. 

 Male genitalia: as in figures 119, 122, and 123 (AB slide June 10, 1937). 

 Female genitalia: as in figure 167 (RWH slide 3477). 



Food plant: Unknown. 



Type: Female, BMNH. 



Specimens examined: 



MEXICO: Guerrero: Amula, 6000 ft., Icf, 2?, Sept. 18, H. H. Smith 

 (AB sUde June 10, 1937; RWH sUde 3477; RWH wing sUde 84), BMNH, USNM. 



Discussion: F. repentina is close to nona but may be separated on 

 maculation as indicated in the key. Unobserved variation may occur 

 in the maculation; however, only tliree specimens are available for 

 examination. The male genitalic differences as pointed out in the 

 key and shown in the figures are diagnostic. 



All of the specimens with the facies of repentina and nona from 

 Arizona have been nona. Further collecting in northern and central 

 Mexico has not turned up additional specimens of either, but this may 

 be a result of each being a fall-emerging species. 



Friseria nona, new species 



Figures 50, 112, 116, 121, 166, 235, 236 



Maculation: as in figiu-e 50. Coloration much as for repentina 

 with the exception that the orange of repentina is generally replaced 

 with buff. Abdomen: mottled buff and gray brown, becoming greasy. 

 Alar expanse: 10.0-13.5 mm. Male genitalia: as in figures 112, 

 116, and 121 (RWH slide 3220). Female genitalia: as in figure 166 

 (RWH slide 3222). 



Food plant: Unknown.
