174 THE ENTOMOLOGIST. 



cream-coloured band of the fore wings is more macular, and has 

 more irregular edges ; the subapical spots are larger, and four in 

 number ; the rufous-brown patch on the hind wings is of a darker 

 tint than in either of the allied forms, and not so well defined ; the 

 white submarginal spots are five in number and sharply defined ; and 

 the tails are differently shaped, being of almost uniform width, not 

 spatulate. The underside resembles that of iphigenia, but the hind 

 wings are darker, having no rufous tinge. Expanse, 2-75 in. 



Habitat. — Salina Cruz, S. Mexico. One ? (August). 



I observed several other specimens of this form at Salina 

 Cruz, but it was difficult to catch, flying among thorny bushes. 

 It must be regarded as a race of H. iphigenia, if the latter be 

 considered distinct from H. diitemnestra, Cram. 



Ancea tehuana, sp. nov. 



Female. — Upper side : Fore wings red, with broadly black apex 

 and outer margin and broad black subapical band, the black areas 

 glossed with brilliant purple except at the margin. Hind wings red, 

 shading to broadly blackish-brown at the outer margin, and brilliantly 

 glossed with purple around the junction of the red and black areas, 

 but the gloss does not extend to the margin. A submarginal series 

 of four small black spots surmounted by white dots. 



Underside pale grey-brown, sharply and uniformly striated with 

 black throughout. Hind wings with four small, black, submarginal 

 spots. Expanse, 2 in. 



Habitat. — Salina Cruz, S. Mexico. Two ? ? taken in 

 August. 



On the upper surface this species much resembles the male 

 of C. chrysophatia, Bates, but is quite different to the female of 

 that species. It can hardly be a dimorphic 2 of chrysophana, 

 as the latter species is not known from Mexico and the under 

 side of tehuana has an aspect of its own, the very marked 

 striation recalling that of the otherwise very difierent A. 

 dominicana, Druce. 



Siderone mars var. angustifascia, subsp. nov. 



Male. — Nearest to S. vulcanus, Feld., from Colombia, but the red 

 band of the fore wings considerably narrower, more shai'ply bent, and 

 at the end of the cell partly interrupted by a number of diffused 

 black scales. The blue gloss on the fore wings is darker and fainter 

 and the hind wings show no trace whatever of the red costal spot. 



iffliiiai.— Huigra, W. Ecuador. 3000 ft. One S (Feb- 

 ruary, 1913). 



Although I only obtained a single example of this sub- 

 species, there is no doubt that it represents a good local race, 

 no Siderone having hitherto been recorded from the Pacific 

 slope of S. America.
