1905] PoPpULAR ENTOMOLOGY. 51 
The Hickory Halisidota, A. carye, Harr., 
is quite different from either of the foregoing. 
The ground color of the forewings 1s ochre- 
yellow, but is heavily dusted with brown scales. 
On the forewings are five, more or less, trans- 
verse bands, or rows of spots, joined together. Hatisidota carye, Harris. 
(Original ) 
The outer two rows of these are pearly, the 
others mostly the ground color of the wings, edged with brown. 
The hindwings are semi transparent, the same as in the Checkered 
Halisidota. The body is of about the same color as the wings, the 
shoulder covers of the thorax being margined with brown on the 
inside. 
The caterpillar of the -Hickory Halisidota is the commonest 
larva of the genus, which we have in this district. It has a black 
head and the body is clothed with dense tufts of white hairs, with 
a ridge of black hairs down the centre of the back, and two pairs 
of long black pencils on the 1st and 7th abdominal segment. 
When full grown it is about one and a half inches in length. 
The female moth lays her eggs in a cluster on the underside 
of a leaf, and the young caterpillars in their earlier stages have the 
_ habit of congregating. As they approach maturity, however, they 
separate, and wander off by themselves. During the past sum- 
mer the writer had a brood of these caterpillars under observation, 
some of which were kept in glass jars. An interesting point noted 
was that when the caterpillars, in their last stage. were being 
returned to the jars, after these had been cleaned, if they hap- 
pened to drop against the sides of the jars, they were able at 
once to hold on to the glass by their feet, instead of dropping to 
the bottom. 
When disturbed all of these Aadtsidota caterpillars have the 
habit of falling to the ground and curling up, remaining in such 
position tor some little time. They can, therefore, be collected 
easily from the trees, or bushes upon which they feed, by simply 
holding, with one hand, aninverted umbrella under the food plant 
and tapping the branches or twigs with a light stick held with the 
other hand.
