GASINA.—HYDRIAS. 205 
Bugaba 800 to 1500 feet (Champion)—Ecvuapor; Amazons, Para!; Sovru-East 
BRAzIL. 
This species varies slightly, some specimens being considerably whiter than others ; 
G. albicollis is, however, very distinct from G. nuda (Cramer). 
CQECULIA. 
Ceculia, Herrich-Schaffer, Samml. aussereur. Schmett. p. 60, t. 19. ff. 86,87; Walker, Cat. vi. 
p. 1404. 
In our country this genus is represented by a single species; the Chiriqui insect is 
-closely allied to the type, C. hella, from Brazil, figured by Herrich-Schaffer. 
1. Coculia bella, sp. n. (Tab. XXII. fig. 3.) 
Male. Primaries pale greyish-brown, mottled and banded with grey from the base to about the middle, and 
with a waved greyish-white submarginal line extending from the costal margin to the anal angle; secon- 
daries pale uniform dull brown, with a very indistinct submarginal waved line: head, thorax, antenne, and 
legs brown (abdomen wanting). Female considerably larger than the male, and with all the light-coloured 
markings very much more distinct. Expanse, ¢, 1? inch; 2, 27 inches. 
Hab. Panama, Volcan de Chiriqui (Ribbe, in mus. Staudinger). 
The female example before me is without any locality, but I believe it was received 
by Mr. Salvin with others sent by Herr Ribbe from Chiriqui. The two specimens here 
-described are the only ones I have seen of this species. 
HYDRIAS*. 
Hydrias, Herrich-Schaffer, Samml. aussereur. Schmett. p. 78, t. 19. ff. 88-91; Walker, Cat. vi. 
p- 1897. 
This genus now contains about twenty species. It is well represented in our country 
‘by six species. 
1. Hydrias lignosa. 
Hydrias lignosa, Walk. Cat. vi. p. 1400°. 
Hab. Panama (Ribbe, in mus. Staudinger).—BRaziL, Rio Janeiro }. 
The male and female lent me by Dr. Staudinger are the only specimens I have seen 
‘from our country. 
2. Hydrias melancholica. 
Aydrias melancholica, Butl. Trans. Ent. Soc. Lond. 1878, p. 82°. 
Hab. Guatemata, Teleman (Champion); Panama, Volcan de Chiriqui 2000 to 3000 feet, 
Caldera in Chiriqui (Champion).—Awmazons, Rio Solimoens?. 
Our Chiriqui examples agree well with the type in the British Museum. 
* This genus requires a new name, Hydrias having been long preoccupied (Ehrenberg, 1830) in Rotatoria,
