296 ENTOMOLOGICAL NEWS. [July, ’08 
On the date above mentioned the smallest larvae found meas- 
ured less thap’one-half an inch in length, while the largest were 
fully an inch long. 
Several of the larvae were kept under observation until nearly 
full fed, when they were removed to a cage and soon after 
pupated, the first pupa appearing on July 6th, the adult of 
which emerged July 18th, in the evening. 
By July 21st nearly all the larvae to be found in nature had 
finished pupating, but two full fed larvae were secured on that 
date. The last larva in captivity pupated on July 28th and 
emerged on August 17th. The pupal period in this locality 
seems therefore to vary from 12 to 20 days, most of the moths 
however appeared in from 18 to 20 days after pupation oc- 
curred. In all, some seventeen adults were reared. The moth 
was identified by Dr. H. G. Dyar as Nonagria permagna Grote, 
but as Dr. J. B. Smith has shown Grote’s permagna and oblonga 
to be synonymous* we assume that oblonga takes precedence. 
The life history of this moth has been given by Prof. Kelli- 
cott in Bull. Buffalo Society of Nat. Sci., Vol. 5, p. 40, 1885, 
under the name of subcarnea; this Dr. Smith has also shown 
to be a synonym of oblonga Grote. } 
Dr. W. J. Holland, in the “Moth Book” (my copy bears the 
imprint of the year 1905 on the title page), says “This is a 
southern species thus far only recorded from Florida,” which 
is certainly an oversight, as Smith records the species from 
New York, New Jersey, Maine, Illinois and California. 
The larva of the moth is quite two inches in length when 
mature and of a pale yellowish color with flesh-colored stripes ; 
it is bare save for a few bristles upon the back and sides. 
The pupa is a bright chestnut color when new, but grows 
much darker as the time of emergence approaches. The moths 
of tha genus® Nonagria are peculiar in that they possess a 
clypeal spine, which is used by them in penetrating the thin 
covering left by the larva to conceal the mouth of the tunnel. 
The pupae show the development of this spine very plainly, 
as may be seen in the illustration. A side view of the head of 
the female moth is also shown which is redrawn from Smith.
