Philampela Vitis, Linn. 



I give this as an instance of rapid developemcnt. The eggs hat< hed 

 in 6 days. The larva vent through its development in 17 days, and be- 

 came an imago 3 weeks later, making only about 6 weeks for the com- 

 plete life, a development possibly paraded by no other of the Sphinginae. 



Catocala ilia, Gtme. 



The larva is very large measuring 3^ inches in length. The head 

 is flattened as usual, eyes prominent with a very slight protuberance on 

 on the upper portion. There are black striations back of the summit 

 and running half way down the cheeks. Body of a dirty brown color, 

 much striated with blackish, and having indistinctly outlined wavy sub- 

 dorsal and stigmatal black bands. Towards the head the brown of ground 

 color has a decidedly reddish cast. There is a sub-dorsal line of slight 

 protuberances one on each segment from the third segment back. There 

 is also a dark Iunule with the horns forward on the 1 ith segment. Un- 

 derneath it is marked very strongly with pink especially on the anterior 

 portion, and between the legs there is a very heavy black dash on each 

 segment from the 4th to the 10th inclusive lessening somewhat on the last 

 three. 



The larva feeds on the various kinds of oak. 



Catocala Oarissima, Huht. 



Head gray brown. Protuberance on summits of eyes prominent 

 Body, ground color gray; very heavily marked and striated with rust-brown 

 which towards the head almost completely covers the body. There is a brown 

 Iunule on the nth segment with horns forward. Underneath clear red 

 brown between 3rd and 6th segment. The 6th and 7th segment between 

 and anterior the legs have each a large nearly round spot. The larva is 

 considerably smaller than that of ilia when full grown, though the imago 

 is one of the largest, if not the largest of all Catocalce. It feeds on Willow. 



Catocala grynea, Cram. 



Length 2 to 2% inches. General color silvery gray with a reddish 

 cast. Eyes marked at summit with a Iunule of yellowish while, and this 

 lined behind with rust-red extending nearly to the mouth. Body more 

 reddish towards the head. There is a very prominent protuberance of a 

 rust-red color at summit of 12th segment. Red very pronounced at the 

 summit of the legs on the 9th and 10th segment. It feeds on crab apple.
