NORTH AMERICAN LEPIDOPTERA. 167 



just hcyond the middle of tlie wing are two prominent, squarish, blaek spots, 

 one on the median, the other on the subcostal vein. A distinct white submargiual 

 line parallel with the outer edge and bordered internally with black scales, es- 

 pecially marked on the costa; the space between tbis line and the outer edge is 

 filled in with deep ochreous longitudinal bars, alternating with black streaks, of 

 which the costal one is the widest and shortest ; these bars do not quite reach the 

 distinct black line at the edge. Fringe ash, twice lineated with whitish ; beneath 

 a pale, whitish, straight, subraarginal line, edged within towards the costa with 

 dark ash. 



Var. leoiiiiiella Packard, Ann. N. Y. Lye. N. H. x, 259, 1873 (PempeMa) ; 

 Grote, Bull U. S. Geol. Surv. Terr, iv, 697, 1878 [Nephopteryx). — Expands 23 — 25 

 mm. Antennae and palpi as \u fenestrella, but the fore wings are more produced 

 towards the apex 'the outer edge being more oblique. Body and base of the fore 

 wings tawny, the thorax being clay yellow; palpi clear ash; basal third of the 

 fore wings tawny yellow, somewhat orange colored externally, outer edge of 

 this colored portion directed regularly and obliquely outwards from the costa to 

 the inner edge \tith three black venular dots along this oblique border. In the 

 ash si)ace beyond is a distinct dark discal dot, and the veins are black. A broad 

 marginal, tawny yellow band, the sides even and parallel; the costa, however, 

 is cinereous to the apex. A marginal black line and a fine dark line in the cine- 

 reous fringe near the base. Hind wings of the usual hue. Abdomen luteous; 

 beneath fore wings smoky, dusky towards the costa; a pale costal streak not 

 forming a submarginal pale line as in fenestrella. Legs dark ashen, whitish at 

 end of joints.

Mr. Grote tells us : " I have examined the type (in poor condition ) 

 and three unset, but fresh specimens. The discal points are present, 

 not absent, as Dr. Packard states. This species agrees closely in 

 form with fenestrella, but differs by tlie ochery color of the basal and 

 marginal fields of the primarias." 



I, too, have examined the types of both species, and from these 

 and other specimens that have come under my observation, have no 

 doubt of the specific identity of the two forms. Leoninella is not 

 even a w^ell marked variety ; yet I allow it to stand as a variety, 

 with the statement of my opinion, till larger opportunities for com- 

 parison are found. 



2. Li. Iiuinilis Rag., Diag. N. A. Phyc. p 11. 1887. — Expands 21 mm. Fore 



wings short, hind margin not very oblique, brownish gray, finely dusted with 



-whitish, the veins streaked with black, interrupted by the whitish cross lines. 



Discal spots distinct, very Vike fenestrella, but wings shorter, darkei", without any 



traces of ochreous; the palpi also seem shorter and thicker. 



California. 



I. have not seen this species. If the structural difference holds it 

 is of course a good species, but no reliance can be placed upon the 

 absence of ochreous from the fore wind's.
