NOTE ON THE LARVA OF MELANOMMA AURICINC- 



TARIUM, GROTE. 



This genus will have to be transferred to the Noctuidse. 



Larva cylindrical, feet normal on joints 7-10, 13, about equally 

 developed. Tubercles minute, setae long, fine, iv. opposite the lower 

 edge of the spiracle, a little nearer to v. than to iii., and rather far behind 

 the spiracle ; setce single, several on the smooth leg plates. Segments 

 obscurely 5-annulate. All green ; spiracles small, brown ; no marks ; 

 cervical shield and anal plate uncornified, invisible. (Head broken off.) 

 Feeds on " hockelberry " (Vaccinium ?). 



Washington, D. C, colls. U. S Nat. Museum. 



The larva resembles the Deltoids. 



The moth is a Noctuid in venation. In Hampson's tables (which I 

 recommend American students of Noctuidse to study) I make it fall in the 

 Palindiinas near the genus Homodes, from which it differs in that vein 7 

 of fore wings does not join the stalk of 8-9 to form an accessory cell, 

 while the third joint of palpi is rather long. Dr. Hulst's account of the 

 genus (Trans. Am. Ent. Soc, XXHL, 294) seems to me erroneous, as I 

 find veins 8-9 long stalked, and 6 arising well above the middle of cell.
