*2 CHEYSOCOEYS. 



expressed in a letter which I received from Mr. 

 Stainton, who kindly examined my Californian speci- 

 mens in June 1873 : 



" My impression is that your Chrysocorys are 

 festaliella. C. erythriella is smaller and darker, and 

 the dark streak near the inner margin seems to stop 

 at the anal angle, instead of turning up along the 

 hind margin to terminate at the apex, as in our 

 festaliella." 



Chrysocorys felicella, sp. nov. 



(PLATE I. FIGS. 2, 2 a, 26.) 



Capite, palpis thorace et abdomine nitide griseo-fuscis. 

 Antennis setaceis. 



Alis anticis sericeis, subpurpurascenti-fuscis, ciliis uni- 

 coloribus ; posticis cum ciliis brunneo-fuscis. 



Tibiis et calcaribus subnitidis. 



Head, face, thorax, and abdomen smooth, with closely 

 appressed, shining, greyish-fuscous scales ; the 

 palpi drooping, scarcely recurved, the second 

 joint with a few projecting scales in front, the 

 third joint smooth and of equal length with the 

 second ; the tongue distinctly yellowish. 



The underside of the thorax and abdomen shining, 

 almost metallic, whitish grey. 



Fore wings unicolorous, smooth, rather shining, fus- 

 cous, with a very slight purplish tinge ; the cilia 

 the same.
