330 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
through the bark making a hole one-eighth inch wide and Due half to 
time-quarters inch long. The bark seemed to be softened with some 
exudation from the mouth. Most of the cuts I examined reached only 
to the wood, but a few were much deeper. In the deeper holes I found

AFFECTING THE LEAVES. 
3. The black walnut sphinx. 
Smerinthu8 juylandis Abbot and Smith. 
(Larva, Plate xi, tig. 2.) 
Order Lepidoptera; family Sphingid.e. 
Larva. — A large pale blue-green caterpillar with a long caudal horn; head small, 
and the body attenuated before and behind, and with seven oblique white bandn. 
When disturbed it makes a creaking noise by rubbing together the joints of the fore- 
part of the body. It enters the earth to finish its transformations. (Harris.) 
Moth. — Very gray, dark or dusfcy brown; wings indented on the outer edges: 
fore-wings with a dusky outer margin, a short brownish dash near the middle, and 
four transverse brown lines converging behind and inclosing a square dark brown 
spot adjacent to the middle of the inner margin ; hind wings with two narrow trans- 
verse brown lines between two brownish bands; thorax with a central brown line ; 
abdominal segments plaited and prominent at the sides. The wings expand from 
2£ to 3 iuches. The females are much larger and of a lighter brownish gray color 
than the males, with the square spot on the fore-wings less distinct. Ranges from 
Massachusetts to Florida and Georgia. (Harris). 
4. Datana integerrima G. and R. 
This species has been found by Mr. Pilate to occur commonly on the 
walnut in Ohio. See p. 150; also Insect Life, l, 177. 
5. Datana ministra (Drnry). 
From Mr. D. S. Harris, of Cuba, 111., we learn that in 1882 the cater- 
pillar of this species " has been so abundant on the black walnut that 
many persons have cut down their walnut trees when they were near 
their houses." See p. 302 ; also Insect Life, i, 125, 161, 177, 200 ; ii, 256. 
6. Schizura leptinoides (Grote). 
This has also been found by Mr. Pilate to feed on the walnut. 
7. Actias huta (Linn). 
Mr. J. P. R. Carney, of Camden, N. J., writes me as follows regard- 
ing the habits of this moth, which he has bred from the walnut : 
In all books of natural history, as far as I have seen, the Luna is accredited with 
spinning a cocoon in the fall and emerging the following May or June. On July 24 
I found on a large walnut, facing the residence of Hon. Thomas Dudley, a fine Luua 
larva. Carefully placing it in my larva box I conveyed it home, and in two days 
after it spun its cocoon and on August 12 merged as a moth, a fine male specimen. Not 
having any female specimen my investigation was brought to a stop, but on looking 
over my notes I find that on several occasions I have taken the moth during May and
