legs whitish, becoming more gray on tarsus; apices of tarsal segments 

 whitish. Forewings fuscous, with faint scattering of whitish tipped 

 scales; main concentration of white at outer margin of discal cell, 

 forming a transverse, crescent-shaped spot; fringe fuscous, with 

 scattering of white-tipped scales. Hindwings uniformly grayish; 

 veins 3 and 4 separate. 



Abdomen : Pale fuscous above, slightly paler below. 



Male genitalia (fig. 70). — Uncus reduced, indistinct, consisting 

 of a small conical lobe. Tegumen reduced, forming a narrow dorsal 

 ring. Vinculum well developed, formed into a somewhat triangular 

 hood projecting posteriorally between valvae. Valva broad at base; 

 outer third divided into two irregularly curved lobes of unequal size; 

 inner lobe approximately twice the width of lateral lobe; apices of 

 both lobes curved inward slightly. Juxta broader than long, with a 

 curved, digitate process arising dorsally. Vinculum and saccus V- 

 shaped. Aedeagus about same diameter throughout length; apical 

 third with 5 stout, distinctly spaced spines in a single row; juncture 

 of ejaculatory duct at middle. 



HoLOTYPE. — North Rim, Grand Canyon, Arizona, d^, June 11, 

 1938, coll. Louis Schelbach, at lights, USNM 69655; in the United 

 States National Museum. 



Host. — Unknown. 



Distribution (map 8). — At present, this species is known only 

 from the type-locality, North Rim, Grand Canyon, Arizona, of the 

 Colorado Plateau. 



Discussion. — This species may be separated most easily from its 

 nearest relative, Bondia shastana, through the use of genitalic features. 

 As evidenced by the male genitalia, particularly in the structure of the 

 aedeagus, these two species are closely allied and probably belong to 

 the same species group. The lobes of the valvae in B. spicata, however, 

 are more robust and of a shorter length (see figs. 69-70) than those of 

 B. shastana. It is further possible that the different number of cornuti 

 (i.e., 5 for B. spicata and 8-13 for B. shastana) reflects a reliable 

 character, although this cannot be analyzed due to insufficient material. 



At present the species is represented only by the male holotype, 

 although it is possible that the unnamed Bondia described on page 

 65 will eventually be associated with this species. The j:)rominent, 

 spicate cornuti present in the aedeagus of this species has suggested 

 the specific name, spicata.
