LEUCARCTIA.—SALLAA. 117 
2. Leucarctia albida. 
Leucarctia albida, Stretch, Ulust. of Zyg. and Bomb. N. Am. p. 208, t. 8. f. 22; Report upon 
Expl. West. 100th Mer. (Wheeler) V. Zool. p. 798, t. xl. figg. 4, 5. 
Hab. Norra America, California !—Britis Honpvras, Rio Sarstoon (Blancaneaua) ; 
‘Costa Rica, Irazu 6000 to 7000 feet, Rio Sucio, Cache (Rogers, Van Patten). 
The examples from Costa Rica agree well with Stretch’s figure. Stretch states 
that he has a specimen of the male from Costa Rica, sent to him by Van Patten, and 
that the female was then unknown. I have specimens of the female before me, and 
find that they are similar to the male, but considerably larger; in no other respect 
‘do they differ. 
SPILOSOMA. 
Spilosoma, Stephens, Ill. Brit. Ent. Haust. ii. p. 74. 
This genus is represented in our country by one species only. 
1. Spilosoma mexicana. 
Sptlosoma mexicana, Walk. Cat. xxxi. p. 291°. 
Hab. Mexico, Oaxaca (Sallé)}. 
ROBINSONIA. 
Robinsonia, Grote, Proc. Ent. Soc. Phil. v. p. 241. 
This genus is closely allied to Sall@a, Felder, from which it is easily distinguished by 
‘its much longer and narrower wings. 
1. Robinsonia formula. 
Robinsonia formula, Grote, Proc. Ent. Soc. Phil. v. p. 241, t. 4. f. 33. 
Hab. Costa Rica (Van Patten); Panama, Volcan de Chiriqui (Trétsch, mus. 
Staudinger).—Cusa | (Poey). 
I have received a single specimen of what I believe to be a female of this species ; it 
‘is in very bad condition. 
2. Robinsonia perfecta. 
Robinsonia perfecta, H. Edwards, Papilio, iv. p. 60’. 
Hab. Mexico, State of Vera Cruz (Schaus)}. 
Mr. Edwards states that this species is closely allied to &. formula, Grote. I have 
not seen a specimen, but from the description I doubt its being distinct. 
. SALLZEA *. 
Sallea, Felder, Reise Nov. Lep. iv. t. 101. f. 10 (Nov. 1874). 
This genus was founded by Dr. Felder for the reception of a species from Mexico. 
* The name Sallea has also been used by Chevrolat (Rev. et Mag. Zool. 1874, p. 286) and Gorham (B.C. A. 
Col. iii. pt. 2, p. 164) for a genus of Cleride.
