 6 cf's, 9 's. Types, Coll. Barnes. 



We have a number pi specimens from Ft. Wingate, N. M.,

Acroncosa similella, sp. nov. 



Very similar to the race castreUa of the preceding species but 

 larger, with longer primaries which are still more heavily sufTused 

 with blue-black than in castreUa; the orange t. a. band is not con-

 whitish, cur\ed line starting from a similar coloured costal blotch 

 beyond which is a dark, oblique streak; median area heavily shaded 

 with a very prominent black, elongate discal spot; orange t. p. 

 line much reduced, defined inwardly by white line preceded by 

 heavy dark shading; distinct, dark apical dash; secondaries smoky' 

 hyaline with a darker marginal border and white fringes. Ex-
