I found a healthy pupa, equally with the larva disinclined to leave 

 its resting place. Wherever throughout the garden a dead branch 

 was to be seen, it was always found to contain one or more of these 

 insects in either the larva or pupa state, and their number can be 

 guessed at when I say that not less than thirty trees had been more 

 or less attacked by this destructive species. Those most affected 

 were cherry, plum, apricot, nectarine, and peach, but I found also 

 one pear and one quince tree each containing a larva, and it is pos- 

 sible that in the course of a short time, the apple trees may also 

 suffer. As in che Cossidce, uEyeriadce, and other internal feeders, the 

 pupa, when near the final change, works its way to the mouth of the 

 burrow, and the moth, as it emerges, softens the cover of chips 

 with which the enti'ance is closed, and so makes its escape. The 

 pupa does not protrude, as is the case in the above-named families, 

 but remains a little distance within the opening. The moths 

 emerge from the pupa about 6 or 7 p.m., and may then be found 

 adhering to the branches, often in copula. They are easily 

 attracted by light, and no less than eighteen fine specimens were 

 taken in one evening at a lamp placed rather high in the house. 

 They are exceedingly delicate insects, and are easily killed iu the 

 cyanide bottle, usually dying in from 20 to 25 seconds. Great 

 care has to be exercised in handling them, as the fine silvery- 

 white scales are very readily removed. The genus appears to be 

 distinctly Tortricid, and has nothing in common (save its method 

 of burrowing) with the Cossidce, in which it has been placed by 

 some authors. 



The following descriptions apply to the stages in which I was 

 enabled to observe it : — 



Larva. — Full grown. Tortricid in form, the head tapering in 

 front, and truncate, pitchy, rugose, with slight dorsal channel. 

 Mouth parts ample. Up[)er side of body, except the 2nd segment, 

 which is pitchy, dull pale chocolate-brown. Under .side sordid 

 white. Spiracles pale pitchy, as are also the thoracic feet. On 

 the dorsum is a series of double ovate shining spots, placed trans- 

 versely, a little darker than the ground colour. These spots differ
