24 THE CANADIAN ENTOMOLOGIST. 



the base of the costal border is also distinctly marked with whitish scales ; 



the dark bordering of the wings is narrower than in any of the other 



American species of Nomiades, narrowing on the fore wings from in front 



backward so as to be a mere line below the middle of the wing, and being 



but a mere line throughout the entire outer border of the hind wing ; the 



tips of the nervules are narrowly blackish ; the fringe is blackish at base, 



whitish beyond, most narrowly interrupted with blackish at the tips of the 



nervules of the hind wings. The upper surface of the wings of the 



female, an inspection of which I owe to the kindness of Mr. Mead, 



resembles that of N. Couperi, but the hind wings are more suffused with 



blue. Beneath, the ground color of the wing is paler than in our orher 



species, being of a delicate pale French gray, slightly darker in the female 



than in the male ; and it differs from the. other species also in the contrast 



between the size of the spots on the fore and hind wings, though a similar 



but not so striking a disparity may sometimes be seen in N. Couperi ; on 



the fore wing these spots, with their rather narrow white borders, occupy 



each an interspace's width, though the transverse bar at the tip of the cell 



is reduced nearly to a line ; on the hind wings the bar at the tip of the 



cell would scarcely be noticed but for its white bordering, and the spots 



are of uniform size, the black pupils reduced to little more than dots with 



a pale bordering as broad as that of the spots on the fore wings. The 



only specimens I have seen come from the southern part of California ; 



probably the species does not occur in the middle and northern parts of 



the State. 



It appears highly probable that the species here described is the true 

 Lye. Behrii Kdw., though not the species (L. Maricopa Reak.") labelled 

 L: Behrii in collections, from the later determinations ot Mr. Edwards. 

 It may also be considered the Lye. Polyphemus of Boisduval, a name which 

 Mr. Kd wards has placed as synonymous with the L. Behrii of his later 

 determinations, /. e., L. Maricopa. In the specimens above described, 

 however, the two upper spots of the extra mesial series of ocelli on the 

 hind wing (to which it would seem that Boisduval referred) are not 

 coalesced, devoid of ocelli, and their separation indicated by a dusky 

 nervule. Boisduval's expression is " on voit a la place des deux petits 

 points discoidaux, une tache blanche cordiforme coupe*e transversalement 

 par une petite ligne noire a peine sensible.'' He also speaks of the female 

 as brown, without reference to the basal suffusion of the wings with blue. 



7 This species has sub-marginal markings on the wings.
