the genus Clothilda. 895 



$ . AnteniiEe black ; palpi white, with a lateral black 

 streak ; head black, with three minute white spots ; pro- 

 thorax brown, thorax and abdomen very dark brown; 

 wings rich brown, the posterior half of the cell of the 

 anterior wings and outside the cell black, including rich 

 red curved marks, just as in G. euryale; beyond this 

 patch are ochre spots, two pairs on the costa^ others in 

 pairs along the outer margin ; there are also others be- 

 tween the median branches ; on the hind wings a broad 

 curved ochre band, deeply sinuate on its outer edge, 

 crosses the wing from the apical to the posterior angle, 

 where it becomes almost white; the cilia of the hind 

 wings bear white spots, inside which are other indis- 

 tinct spots in pairs: beneath, rich ochre, with black and 

 red spots corresponding to those of the upper surface, 

 the latter being larger ; at the base of the wing are some 

 transverse and longitudinal pale marks, and the ochre 

 marks on the rest of the wing correspond with those of 

 the upper surface ; on the hind wing there is a promi- 

 nent red spot on the middle of the costa, an irregular 

 black line, bordered with white, crosses the wing, three 

 transverse white lines cross the cell to the submedian 

 nervure, between which and the inner margin are longi- 

 tudinal white lines; beyond the cell the nervures are 

 black, and cut a deeply sinuate band of whitish; on the 

 margin are large pale spots in pairs. 



Hab. — Highlands of Costa Rica [Arce) . In Mus. Salv. 

 and Grodm. 



This species is closely allied to G. euryale, and evi- 

 dently represents that species in the highlands of Costa 

 Rica. For some time I considered this specimen to be 

 a female of G. euryale, but having acquired true females 

 of that species, I am now convinced that the Costa Rican 

 Clothilda must be distinct. 



My reasons for separating it may be thus shortly 

 given. Individuals of G. euryale do not vary from one 

 another in any appreciable degree, nor do members of 

 other species of the genus, as C.pantherata, or G. numida. 

 The sexes also are alike, both in G. euryale and G. j?an- 

 therata, and, moreover, species from the highlands of 

 Costa Rica, though evidently closely allied to their repre- 

 sentatives in the highlands of Guatemala and Mexico, 

 very frequently are appreciably different. Hence the
