figured by Cramer in his last Volume under the name of Halyst, as the 

 female of tins species. Hubner's genus is erected for these two spe- 

 cies of Cramer's, which Mr. Walker has introduced into different 

 Groups of his genus "Euchromia," without, however, being autopti- 

 cally acquainted with both forms.

 (August, 1866.) 



Head, above and beneath, palpi and prothoracic parts, orange-yel- 

 low. Maxillce, rather long, blackish. Antennae, dull brownish, simple 

 or nearly so. Thoracic disc, orange-yellow, of a little paler shade than 

 the "collar" and caputal parts. Tegulae, concolorous with the wings, 

 discolorous with the thorax, blackish, margined and overlaid or shaded 

 with bluish-green scintellate scales. Abdomen concolorous with the 

 wiugs, dull obscure blackish or brownish, with prominent bluish-green 

 reflections equally disposed, but less apparent on the under surface in 

 the female. Terminally, in the male, the genital appendages and anal 

 segments are clothed with yellow scales; beneath, the anal segment is 

 provided with two prominent orange sub-lateral tufts of longer scales; 

 centrally, the lateral claspers have darker, sciutellate scales. In the fe- 

 male, the abdomen terminates acutely and a pre-anal orange-yellow 

 band is continued entirely around, the extremity of the abdomen being 

 blackish and scintellate. Legs, blackish, sciutellate; in the male, the 

 yellow color of the prothoracic parts beneath, extends over anterior and 

 middle coxae and femora. 



Wings, entirely dull obscure brownish or blackish, with an evenly 

 disposed metallic reflection, which varies from bluish to greenish ac- 

 cording as the light falls on the wings. The primaries are more bril- 

 liant than the secondaries. Beneath, the same as above, but the re- 

 flection is hardly so prominent. Exp. % . 1.50, 9 , 1.80 inch. Length 

 of body, % , 0.50, 9 , 0.55 inch.

Nearly resembles the Brazilian Apistosia judas, Hiibner, but is a 

 slightly larger species, differing by the terminal abdominal coloration 

 and prominently by the dark patagia, which, in Hubner's figure and as 

 expressed by Walker's diagnosis, are concolorous with the rest of the 

 thorax and yellow.
