distributed around the roots of the trees. Mr. Koebele men- 

 tions the fact of having seen a single Hve oak (Quercus virens) 

 standing in an open field which contained many larvae, and 

 their debris, resembling sawdust, was distributed over the ground 

 around the roots of the tree more than six inches in depth. 

 At the period of pupation the larvae, as is customary with 

 the Cossidce, takes its position near the surface of the bark. 

 The tunneling is usually conducted near the surface, from one- 

 quarter to one inch beneath the bark. After imaginese emerge 

 their pupa-cases are left protruding through the bark. Speci- 

 mens of the larvae and eggs were not preserved for description. 



Ptipa-case. The long testaceous pupa-case is provided with 

 an irregular series of five tuberculations on each side of the 

 anus ; the segments have a narrow mesial corinei near the 

 spiracles.

THE NORTH AMERICAN SPECIES OF NONAGRIA. 



By a. R. Grote. 



But few species of this genus, which is allied to Heliophila 

 {Leucania), are found in collections. After having seen the types 

 of the supposed species described by Mr. Walker, I can discard 

 them as not belonging here (c. f. my notes in " Illustrated Essay " 

 on the Noctuidce). The extent to which the species vary is not 

 known. Guenee describes : 



Nonagria Ijtguhiata, Noct. I., 104. " 21 mil. Habit of Fulva. 

 Fore wings of a dirty ochrey white, the nervules a little paler, 

 and with blackish atoms strewn here and there on the disk, and 

 chiefly below median vein. A black streak interrupted and situ- 

 ate beneath the sub-median vein and filling the space which usu- 

 ally divides the two median lines, the elbowed (t. p.) line partly 

 marked in black. A series of terminal elongated dots. Hind 

 wings dirty white. Beneath, the four wings of a yellowish white 

 without markings. A female specimen from New York in Mr. 

 Doubleday's collection." 



The type of this ought to be in the British Museum collec-
