Hob. Guatemala, Polochic valley (F. D. G. & 0. £.), Panima (Champion) ; Hon- 

 duras (mus. Staudinger) ; Nicaragua (Belt) ; Panama, Veraguas (Arce), Lion Hill 

 (McLeannan). — South America, from Colombia to S. Brazil. 



Mons. Mabille in 1883 (Bull. Soc. Ent. Belg. 1883, p. li) divided P. pygmalion of 

 Cramer as understood by the older writers into five species, and in 1888 (Le Nat. x. 

 p. 77) he added another, P. perillus. Of these we recognize the latter without 

 difficulty, and also P. distans (H.-S.). P. pygmalion itself we are inclined to look 

 upon as a widely ranging rather variable species. Central-American and Colombian 

 specimens have the middle diaphanous band of the primaries narrow ; but it is always 

 present, so that we are in doubt whether M. Mabille's name, E. thermus 3 , is applicable 

 to them, as in that species this band is said to be absent. In specimens from South 

 Brazil this band becomes an oval bifid spot, and in this form is Erycides hewitsoni of 

 Mabille. Every intermediate form exists, so that any separation is difficult if not 

 impossible. 



The most northern limit of the range of this species is Eastern Guatemala, where 

 we found it in some abundance in the valley of the Polochic river up to an elevation 

 of about 3000 feet. 



The male genitalia have a long decurved tegumen, from the middle of which on 

 either side is a narrow rod reaching nearly to the end of the tegumen, but raised 

 above it ; the harpagones have a rounded serrate end, the serration passing in a curve 

 inwards over the disc ; there is a slight depression on the dorsal edge before the end. 

 (See Tab. LXXVI. fig. 16.) 



2. Photides Mus, sp. n. (Tab. LXXVI. figg. 17, 18 6 .) 

 P.pygmalioni similis, sed maculis hyalinis anticarum (prasertim iis ad apicem) multo majoribus striisque caeruleis 

 saturatioribus et angustioribus. 



Eab. Mexico, Ventanas (Forrer), Tampico (Richardson), Paso de San Juan (Schaus). 



The large transparent spots of the primaries and the deeper tint of the blue stripes 

 of this Mexican form of P. pygmalion render it fairly distinct. It appears to be 

 somewhat rare, though our specimens are from widely separated localities. Mr. Forrer's 

 examples were taken at Ventanas in the State of Durango at an altitude of 2000 feet 

 above the sea. In Vera Cruz it occurs at a much lower elevation. 



The male genitalia are precisely like those of P. pygmalion.
