NELO.—SANGALA. 153 
1. Nelo chrysomela. (Tab. XIV. fig. 7.) 
Nelo chrysomela, Butl. & Druce, Cist. Ent. i. p. 117°. 
Hab. Costa Rica (Van Patten 1, mus. D.), Cache, San Francisco (Rogers) ; PANAMA, 
Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Mr. Champion met with WV. chrysomela locally in great abundance in Chiriqui about 
the banks of rocky mountain-streams, the species being fond of settling on the partially 
submerged rocks and stones within reach of the wet spray; it appears to be equally 
common in Costa Rica. These specimens do not show any variation of importance. 
EV AGRA. 
Evagra, Boisduval, Lép. Guat. p. 87. 
Numerous species of this genus are known from Tropical America. 
1. Evagra jalifa. (Tab. XIV. fig. 15.) 
Evagra jalifa, Boisd. Lép. Guat. p. 88°. 
Hab. Mexico (Sallé!); Honpuras 1. 
Through the kindness of M. C. Oberthiir I have been enabled to see the type of this 
species ; it is the only specimen known to me, and I do not feel at all certain that it 
should be placed near the genus Sangala. 
2. Evagra ribbei, sp.n. (Tab. XIV. fig. 14.) 
Primaries dark blue-black, glossed with very dark blue, crossed near the apex by a wide semihyaline whitish 
band; secondaries dark glossy blue, with four whitish streaks between the veins on the outer margin; 
the underside almost the same as above, the white markings rather more distinct: head, thorax, and 
tegule black; the collar and underside of the head orange; antenne and palpi black; abdomen above 
bright glossy dark blue, beneath and the thorax dusky white ; legs dusky white. Expanse 13 inch. 
Hab. Panama, Volcan de Chiriqui (Ribde, mus. Staudinger). 
One example. This beautiful species is contained in the rich collection of Dr. Stau- 
dinger, who has kindly lent me the specimen for description in this work. 
SANGALA. 
Sangala, Walker, Cat. i. p. 384. 
Walker founded this genus for the reception of two species from Colombia. The 
species of Sangala are most beautiful insects, but I think it extremely doubtful whether 
the genus is represented in our country; I include it on the authority of Boisduval, 
never having seen or received any specimens from any locality north of the Isthmus of 
Panama. 
1. Sangala celisigna. 
Sangala celisigna, Walk. Cat. ii. p. 384’. 
Letocles alcera, Boisd. Lép. Guat. p. 84°. 
Hab. UNicaracua?.—CotomB1a, Bogota! (Birchell, mus. D.), Villavicencio (Chapman, 
mus. D.).
