5. Acronycta Icpusculina Guenee, Bull. Buff. Soc. N. S., i, p. 130. 



A fresh specimen sent by Mr. Behrens gives me some reason to doubt 

 this determination and to suspect a distinct species, allied to A. leporiiia 

 and A. lepusculina^ in California. The fore wings are narrower, the 

 markings more obliterate above. A different material from that now 

 accessible to me is needed to make any change in this determination or to 

 confirm it with positiveness. 



6. Acronycta perdita Grote. 



^ Nearest resembling A. xyliniformis of any of our Eastern species, 

 but larger, more robust, and with the fore wings even darker. There is 

 an absence of any softer shadings before and behind the transverse 

 posterior line. All the markings are coarser. The terminal series of 

 black interspaceal mirks are large and heavy. The transverse posterior 

 line has the outer dentations more uneven ; the teeth on veins 4 and 6 

 are notably longer ; the line itself seems hardly so near the terminal 

 margin as in xylijiiformis. The black shade streak at anal angle is heavier 

 and the dash on the median space is different in position, more incon-
