/^;/,/A;/_California. (Coll. Dr. Behr.) 



Described from i ^ ? raised from the larva by Dr. Behr of San 

 Francisco, California. These two specimens are very closely allied to 

 A' dictiva of Europe, and it is not without hesitation that I have de- 

 scribed them under a new specific name. The chief points of differ- 

 ence are a paler tint of brown on the primaries, and a more uniform 

 color, the extension of the costal cloud to the median interspaces, the 

 much narrower and less conspicuous wedge-shaped dash at the anal 

 angle ; and in the posterior wings a rounded instead of produced anal 

 angle. The anal cloud partakes of the characters of both the allied 

 European species, having the white line above the fringe of N. dictcca, 

 and the small white spot on the inner margin of N. dictccoides. Finally 

 the anterior wings are not so wide in proportion to their length as in 

 the European species. 



Larva. — Dr. Behr informs me that the larva is pale green on the 

 dorsal line, darker green and somewhat mottled on the sides, with 

 faint traces of a supra-pedal light stripe, somewhat darker than the 

 dorsal line, with a straight red horn on the a^ial segment. Body small 

 for the size of the imago, head large, rounded, the larva in appear- 

 ance strongly resembling that of L. camelina of Europe. This larva 

 is clearly different from its European allies ; and it is this decided 

 structural peculiarity which has induced me to give the insect a new 

 specific name.
