118 ENTOMOLOGICAL NEWS. [ March, ’o08 
twigs while two half grown specimens were found on the bark 
at the base of the tree in the shadow of some drooping rasp- 
berry leaves. On the underside of a dead branch of some- 
what greater diameter than a lead pencil, two well grown larvee 
were found. 
After the tree had apparently been robbed of all its caterpil- 
lars and several days had passed without finding any, in the 
folds of a muslin bag tied on a living branch, three mature 
larvee were discovered. 
A trick was then tried that had proved successful in the 
search for Catocala piatrix larve. Sticks or dead branches were 
leaned against the tree and, in the morning, several larve were 
found on the under side of the sticks. 
I am sure that when no shelter is to be found on the tree, 
the larve, after the night’s feeding, leave the tree and hide 
beneath leaves or find other retreats. 
I found this so in C. piatrix by scattering pasteboard and 
folds of paper beneath walnut bushes and in the morning se- 
curing the larve beneath the boards or in the folds of the 
paper. 
Small larve of all species of Capoten perhaps, are some- 
times found in the bark grooves or cracks and, perhaps, al- 
ways with the head down and in most cases within three or 
four feet of the ground. We have never climbed for any but 
hickory species and then only when the rough loose bark ex- 
tended beyond reach. 
I recall a walnut bush that grew near the edge of a low bank 
and the water had worn a hole down among the roots. I thrust 
my hand down the hole and felt among the rootlets till I found 
a fine large C. piatrix larva. 
On the beastie of a willow that had fallen over, a very 
large cara “worm” was discovered near the ground. 
Beneath the loose bark of shag-bark hickory, larve of a 
number of species of Catocala can be easily found and usually 
near the ground, but sometimes higher if the loose bark ex- 
tends upward. 
On hickory we have taken larve of C. residua, C. habilis,
