84 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
thoracic paler bands are seen on the thorax, and there is always a pale transverse 
band behind the middle of the elytra, and a sutural band. In the male the beak is 
equal to three-fourths the length of the body ; inthe female to five-fourths. It breeds 
entirely on hickory nuts. (Riley.) 
The following insects also occur on the hickory : 
77. The Luna moth, Actias luna. (Linn.) 
78. The hickory leaf roller, Tortrix (Lophoderus) juglandana Fernald. 
(Can. Ent. XI, 155.) 
79. Eburia quadrigemina Say. Issuing from hickory trees in July, com- 
mon. (McBride.) 
The following Tineide feed on the hickory according to Chambers : 
80. Lithocolletis caryefoliella Clem. 
81. Lithocolletis caryealbella Chamb. Larva in a tentiform mine in the 
under surface of the leaves. 
82. Aspidisca lucifluella Clem. Larva in a small blotch mine, from which 
it cuts out its pupal case. 
83. Coleophora caryefoliella Chamb. (and Clemens ?). Larva feeds in a 
cylindrical case attached to the under surface of the leaves. 
84. Nepticula caryefoliella Clem. Imago unknown. Larva in a linear 
crooked mine on the upper side of the leaves. 
85. Ypsolophus caryefoliella Clem. Larva sews together the leaves. 
86. Gracilaria sp. (probably G@. blandella Clem.) Imagounknown. The 
larva when young makes a linear whitish mine in the upper sur- 
face of the leaves. 
87. Phycita nebulo (juglandis). A pyralid living on the walnut. 
INSECTS INJURIOUS TO THE BLACK WALNUT. 
(Juglans nigra.) 
AFFECTING THE TRUNK. 
The chief enemy of this tree is the hiekory and locust tree borer, 
(Cyllene picta). Fitch states that the beetles which are reared in this 
tree appear to constitute a distinct variety of a larger size than usual 
and with their yellow marks changed more or less to a white color. 
AFFECTING THE LEAVES. 
1. THE BLACK WALNUT SPHINX. 
Smerinthus juglandis Smith-Abbot. 
Order LEPIDOPTERA ; family SPHINGID 2. 
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 bands. When dis- 
turbed 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. ) 
The moth is very gray, dark or dusky 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 enclosing a square dark brown
