COLORADIA.—COPAXA. 173 
1. Coloradia clazomenia, sp. n. (Tab. XVI. fig. 5.) 
Primaries and secondaries uniform brownish-black, the veins rather darker, the primaries with an indistinct 
greyish marginal band extending from the apex to the anal angle: head, thorax, abdomen, legs, and 
antenne brownish-black. Expanse 33 inches. 
Hab. Panama, Volcan de Chiriqui (Ribbe, mus. Staudinger). 
2. Coloradia marathusa, sp.n. (Tab. XVI. figg. 33,42.) 
Male. Primaries and secondaries dark reddish-brown, lightest near the base of the primaries; the primaries 
with a slightly greyish transverse line crossing from the costal margin to the anal angle, and with 
several obscure dark markings between if and the outer margin; the secondaries rather darker; the 
underside of both primaries and secondaries much lighter: head and thorax dark brown ; abdomen dark 
reddish-brown above, much paler beneath ; antenne and legs dark brown. 
Female. Primaries and secondaries uniform pale brown, the wings thinly clothed with scales: head and thorax 
dark brown; abdomen pale yellowish-brown; antennew and legs brown. Expanse, ¢, 24 inches; 
@ , 3¢ inches. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
I am a little doubtful if this species should be placed in the genus Coloradia; the 
neuration is very similar, the only difference being, so far as I am able to see, a rather 
shorter cell in the secondaries. The primaries are somewhat shorter than in the other 
species. I have only seen two examples, one of each sex. 
Fam. SATURNIIDA. 
COPAXA. 
Copaxa, Walker, Cat. v. p. 12385. 
This genus was formed by Walker upon three species (C. canella, C. decrescens, and 
C. expandens), from Tropical South America. Six species, including the two last named, 
inhabit our country; several others, one of which is very closely allied to C. expandens, 
are also known from West Africa. 
1. Copaxa decrescens. 
Copaxa decrescens, Walk. Cat. v. p. 1287'; Maassen & Weymer, Beitr. zur Schmett. ff. 44, 45. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers); Panama, Volcan de Chiriqui 
(Ribbe, mus. Staudinger), Bugaba (Champion).—Cotomsia, Bogota (mus. D.); Brazit, 
Rio Janeiro 1. 
This insect appears to be rare in our country; I have only seen a very few examples. 
The coloured figures of Maassen and Weymer are poor, and show the light markings 
very much more distinctly than they are in the examples before me. 
2. Copaxa multifenestrata. 
Euphranor multifenestrata, Herr.-Schaff. Samml. aussereur. Schmett. pp. 61, 84, t. 96. f. 551°. 
Hab. Mexico, Jalapa (Hoge), Cordova (Riimeli); Nicaragua, Chontales (Belt) ; 
Panama, Chiriqui (mus. Staudinger).
