296 ENTOMOLOGICAL NEWS. [July, '08 



On the date above mentioned the smallest larvae found meas- 

 ured less than 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 i8th, in the evening. 



By July 2 ist 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 I7th. 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 oblon.ga 

 to be synonymous* we assume that oblon.ga 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 subcarnca; 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 thq 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.
