clominal segment and a stronger one on the 8th, forming a 

 blunt V. Black lines bound the anal pro-legs. The true legs 

 are flesh color with green at the joints. Pro-legs, body color. 

 Head, black above, except at the lobes, where a dirty reddish 

 yellow lunule is conspicuous. About the mouth, the color is 

 lighter, flesh color and appears in dots and streaks. The ven- 

 tral surface is pale green with black spots. 



This larva from the time of hatching to the time of spinning 

 is the most active I have ever had anything to do with, but is 

 apparently without fear, as it seems to prefer to crawl on one's 

 fingers. You can't leave one for a minute and expect to find 

 it again. It is strongly like the larva of C. jraxini, differing 

 only in minor details. In spinning, it seems to prefer the top 

 or middle of the jar and the willow leaves, to paper. It seems 

 to be hardy on black willow, except that it does not reach the 

 size of the aspen feeder. 



On the 25th of June ants destroyed seven grown larvae of 

 this species, all the "worms" in one jar. The pupa of C. r dicta 

 is rather long and slender, dark, reddish brown with whitish 

 prunescence. Wing cases not darker than the body. The 

 chrysalis when disturbed is quite a wriggler, like the larva. 

 The first imago was a white one and on July 2Oth and the last 

 one was a dark one and on August 5th. The imagoes straggled 

 like the larvae. From the eggs of the white female all the 

 moths, save one, were white, and from the eggs of the dark 

 female most of the moths were dark. There was no difference 

 in the size or color of the larvae of the two varieties. 



The junior author had larvae quite three inches long, fed on 

 aspen, but no luck in securing imagoes as her larvae died when 

 full grown. She finds the imagoes in the woods among the larg- 

 est of Catocala, but bred on black willow by the senior author, 

 they were no larger than concumbens. By striking a smart 

 blow on the tree just over a resting rclicta moth the junior 

 author was surprised, on several occasions, to see the moth drop 

 to the ground and remain motionless, even allowing itself to be 

 picked up. 



On the 24th of May the first larvae of concumbens hatched.
