PENORA.—XENOSOMA. 165 
This delicate species is quite distinct from any other known to me. It appears to be 
scarce, Mr. Champion having met with very few examples; from Arcé I only received 
a single specimen. 
6. Penora ombrea, sp. n. (Tab. XV. fig. 8.) 
Primaries and secondaries uniform dusky brown, rather lighter from the base to about the middle: head, 
thorax, and abdomen pale dusky brown; antenne and palpi pale brown; underside of the abdomen and 
the legs whitish-brown. Expanse 1} inch. 
Hab. Costa Rica (Van Patten, mus. D.). 
This species is allied to P. discifera, Walker, from Brazil. 
| XENOSOMA. 
Xenosoma, Felder, Reise Nov. Lep. t. 99. f. 9. 
Eloria, Walker, Cat. iv. p. 813; ibid. xxxii. p. 339 (=Penora, Walker, ante, p. 168). 
This genus is allied to Penora, Walker, from which it differs in many respects. 
Eloria, Walker, being identical with Penora, Walker, I adopt Felder’s name. 
Several species of the genus are known from Tropical America; we have to record 
three from our region. 
1. Xenosoma flaviceps. 
Eloria flaviceps, Walk. Cat. xxxii. p. 339’. 
Xenosoma nigricosta, Feld. Reise Nov. Lep. t. 99. f. 9’; Stretch, Cist. Ent. ii. p. 16. 
Hab. Mexico!; Guatema.a?, Zapote, Panzos (Champion). 
I have not received any specimens of this species from Mexico, and in Guatemala it 
is far from common. 
2. Xenosoma nigromarginatum, sp.n. (Tab. XV. fig. 4.) 
Primaries and secondaries hyaline-white, the primaries with the costal and outer margins and all the nerves 
brownish-black ; secondaries margined with brownish-black from the apex to near the anal angle: head 
yellow ; antenne and palpi black ; thorax brown, speckled with white scales ; tegule white, with a small 
yellow spot at the base; abdomen brownish-white, the anal segments bright yellow ; legs brown. 
Expanse, ¢ 2 inches, 9 23 inches. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
Mr. Rogers only obtained two specimens of this very distinct species. 
X. nigromarginatum is most nearly allied to X. flaviceps, but from that species it is 
at once distinguished by the black nerves and margins of the primaries, also by its 
larger size and much more robust appearance. | 
3. Xenosoma nicander, sp.n. (Tab. XV. fig. 6.) 
Primaries whitish-hyaline, the costal margin and apex smoky black (more so in the female than in the male); 
secondaries whitish-hyaline, narrowly margined with black from the apex to near the anal angle: head, 
thorax, and tegule bright yellow; antenne and palpi black; abdomen brownish-white, the anus bright 
yellow ; legs pale brown.. Expanse 14 inch.
