[Read April 20th, 1904.] 



Plate XXVII. 



On the appearance of Mr. Godman's paper on Erycinidm, 

 Trans. Ent. Soc. Lond. 1903, Part IV, I decided to work 

 out the hitherto unnamed species in Mr. Herbert J. 

 Adams' collection, the result being the discovery of the 

 ten new species here described and figured. The Peruvian 

 species were all taken by Messrs. Watkins and Tomlinson. 



Ettrygona s^tbargentea, sp. nov. (Plate XXVII, fig. 1.) 



(J. Upper-side. — Fore-wing blackish-brown, paler at apex ; hind- 

 wing blackish-brown, paler along costa. 



Under-side. — Fore- wing silvery white crossed by two brown lines, 

 one beyond cell, the other near outer margin ; the ground colour 

 beyond the inner line darker than basal half, the outer line inwardly 

 edged with a row of silvery white spots ; hind-wing silvery white 

 crossed by a brown line beyond cell, this line acutely angled below 

 lower median nervule, two waved submarginal brown lines, outer 

 margin darker as in fore-wing. 



Expanse 46 mm. 



Hob. Bogota, Columbia, 1 $. 



This fine species appears to have no near ally in its 

 genus. 



Mesosemia elegans, sp. nov, (Plate XXVII, fig. 2.) 



(J. Upper-side. — Fore- wing black crossed by a curved white 

 band beyond cell, this band widely edged inwardly with pale blue, 

 which colour extends into cell encircling a black spot, this spot 

 contains three white points one in centre and two beyond, the outer 

 edge of white band narrowly pale blue ; hind-wing black crossed 

 by a similar band to fore-wing but the l>lue area much more 

 restricted, and three black lines, broken in middle, traversing inner 

 blue area.
