P. contrasta B. &■ McD. (39 f) exhibits just the contrary colouring, the middle area being white contrasta. 
and the basal and marginal areas deep brown with double dentate transverse lines, the black-centred maculae 
surrounded with black, between them a brown costal-marginal spot extends down; hindwing yellowish-brown, 
at the margin smoke-brown. Arizona. 
P. endopolia Dyar (39 g) is extremely similar to contrasta, but according to the kind information endopolia. 
by Mr. Schatjs who compared the type with the preceding, it differs in its larger size, and the white colour 
does not extend postmedianly beyond the submedian fold, above the reniform macula there is at the costal 
margin only one white dot, in contrasta there are two. Mexico. 
102. Genus: Xamaiiga iih Stgr. 
This genus not having been quite satisfactorily grouped unites not cpdte homogeneous species, which 
were inserted here owing to the lack of distinctive marks. Proboscis developed, palpi erect, the 2nd joint in 
front scaled, the last joint short, porrect; frons smooth, thorax covered with scales, in front and behind with 
loose tufts, the abdomen only with a small tuft on the first ring. Antennae of a very different structure. The 
genus is chiefly distributed in the north of America, but also represented in Mexico and farther down to the 
south. 
N. licentiosa Sm. has ash-grey forewings irrorated with brown, with rather indistinct and interrupted licentiosa. 
markings, of the transverse lines the anterior line is double, the posterior line on the veins prolonged into streaks; 
the large maculae are strewn with white, not marked; the light undulate line is on both sides bordered with 
blackish; hindwing white, at the margin brownish, in the $ with a broader marginal band. The d antennae 
are very long-combed. From Utah. 
N. costa B. tb Benj. (39 f) is allied to the following; the whitish ground of the forewing is irrorated costa. 
with brown, and in the whole costal half as far as below the cell darkened by blackish-brown like the collar 
and shoulder-covers, too; the single transverse lines are somewhat lighter scaled on the averted sides, the maculae 
quite indistinct; undulate line scarcely lighter. Hindwing diaphanous white, in the distal half smoky. Expanse 
of wings: 29 to 31 mm. Arizona. 
N. continens Edw. (39 g). Forewing yellowish red-brown, in the central area irrorated with black, continens. 
with black single transverse lines, the anterior line strong, removed far into the centre, the posterior line distally 
white-edged; of the maculae only the small white, black-centred reniform macula is present; undulate line 
proximally shaded with brownish. Hindwing white, at the margin narrowly brownish, in the $ quite brown, 
here also the forewing is darker. Arizona. 
,, N. seitzi Barnes & Benj. ( ined.) (39 g), allied to continens , somewhat larger, forewing as in suffusa, seitzi. 
but the black irroration of the central area very much reduced. Hindwing diaphanous white, only the ends 
of the veins and a fine marginal line are blackish-brown. Holotype 1 paratype Huachuca Mts., allotype $ 
So. Arizona in the Coll. Barnes. Responsible for the denomination and description, signed by Wm. Barnes 
and F. H. Benjamin, Decatur, 111.“ 
N. tapeta Sm. (39 h) originally described as Oligia and partly taken to be a form of continens, separated tapeta. 
by different, less densely scaled and more slender palpi; forewing yellowish red-brown, with single, black 
transverse lines, the posterior line distally bordered with yellowish; the upper maculae are whitish, the ring- 
macula is punctiform, the reniform macula is brown-centred, at the hind-margin in the central area a dark 
spot, behind the yellowish undulate line the veins are striped yellowish. Hindwing white, the veins and margin 
brownish. Florida. 
N. suffusa B. d; McD. (39 g, h) is very similar to a light form of continens, but the quite different suffusa. 
genitals prove it to be a distinct species; separated by its much more intensely irrorated exterior, the more 
irregular course of the anterior transverse line and the narrower middle area at the hind-margin; the hindwing 
has a much broader dark marginal band. Arizona. — The form rubida B. & McD. (39 h) is on the forewing rubida. 
deeper red, less intermixed with ochreous scales, the anterior transverse line has a more regular course, and 
the reniform macula is more distinctly prominent owing to its being more intensely white-scaled. California. 
N. perolivalis B. <£.• McD. (39 h) is on the forewing olive-green, densely strewn with white and perolivalis. 
black, with irregularly dentate single transverse lines, being the lightest before the anterior line; the reniform 
macula is large, irrorated with white, the light undulate line proximally irrorated with black. Hindwing diapha¬ 
nous white, at the margin broadly smoky. Arizona. 
N. viridescens B. & McD. (39 i). Anterior body and forewing brown mixed with emerald-green, viridescens. 
with double, green-filled transverse lines, the maculae filled with green and only partly surrounded with green, 
the very large coniform macula above and below open, filled up with dark and surrounded with green; the 
whitish undulate line is proximally bordered with broad green crescents, the marginal area behind it green 
with brown veins. Hindwing yellowish-brown. Arizona, September.
