more of the moths, and as the form differs from Necopina, the only species 

 with which, in my opinion, it could possibly be confused, not only in the 

 imago, but also in the larval and pupal stages, I have no hesitation in 

 describing it as a new species. 



Gortyna sErata, n. sp. 



Very similar in general appearance to G. Necopina. The colour of 

 the primaries more bronzy, especially in the median space, and with a 

 distinct purplish or sometimes dull mauve shade beyond the t. p. line. 



Head and thorax similar in colour to the primaries, powdered with 

 white atoms, as in Necopina; abdomen lighter, similar in shade to the 

 secondaries, and more evenly gray. In Necopina the dorsal tuft is 

 somewhat conical, and projects forward, while in ALrata it is more 

 transverse and slopes backward. Antennae brown or grayish, slightly 

 marked with whitish, springing from a whitish collar. 



The wings, especially the primaries, are also somewhat powdered 

 with white, but much less so, and, in general, less evenly so, than in 

 Necopina. Of the types, the one which comes nearest to Necopina is 

 No. 5, and in this the powdering is almost as even as in that species. 

 The markings, as a rule, are obscure, especially in the flown specimens, 

 but the t. p. line is generally fairly well marked, and the t. a. line can 

 occasionally be made out either in whole or in part. 



In five out of the six bred specimens there are a few yellowish spots 

 or dots running in from the costa a little before the apex, and in four out 

 of the six there are on costa of primaries four yellowish dots, the first 

 being just above the reniform and the others between it and the pre- 

 apical series, at about equal distances apart. The t. p. line, when 

 strongly marked, as in type No. 6, a most remarkable specimen, is seen 

 to be double, and sometimes, as in type No. 2, the space within the lines 

 is more or less filled with yellowish scales. 



The orbicular and reniform are generally obsolete, or, at most, 

 indicated by dark shades only, but in type 6 both are present, the former 

 only represented by a yellowish dot, but the latter well developed and 

 consisting of a central curved brownish-yellow line surrounded by five or 

 six yellowish or whitish spots of varying size and shape. 



In several of the specimens there is a purplish or dull mauve shading 

 within the t. a. line, or between it and where the basal line should be 

 The s. t. line, when shown, is strongly dentate, but is generally indicated 

 merely by the difference in shade between the dull mauve within and the
