INSECTS INJURIOUS TO THE HICKORY. 83 
72. PIG-NUT LEAF WEEVIL. 
Conotrachelus elegans Say. 
Order COLEOPTERA; family CURCULIONID®. 
While engaged in laying its eggs sometimes cutting off the leaves of the pig-nut 
hickory, a weevil of moderate size, closely resembling the plum weevil. 
We have observed this weevil at Providence, busily engaged the last 
of May laying its eggs in the partly rolled-up leaves of the pig-hickory 
(Carya porcina), and during the process cutting off the leaves, which 
hang down, wither, and turn black. 
73. THE PIG-HICKORY SLUG-WORM. 
Selandria sp. 
A pale-green slug-worm, resembling in form the naked larva of Selan- 
dria carye, with several rows of short, forked white hairs; quite abun- 
dant at Providence May 30th, eating roundish holes in the leaves of the 
pig-nut hickory. 
74, THE HICKORY SLUG CATERPILLAR. 
Thecla calanus (Hiibner). 
Order LEPIDOPTERA ; family PAPILIONID 2%. 
Feeding on the leaves of the pig-hickory at Providence May 50th and 
later, a pale-green, flattened, long, oval, cylindrical caterpillar, flat be- 
neath ; the body rounded above and covered with short hairs ; changing 
to a delicate small butterfly, with the hind wings tailed. 
AFFECTIVNG THE FRUIT. 
75. THE HICKORY-SHUCK WORM. 
Ephippophora caryana Fitch. 
Order LEPIDOPTERA ; family TORTRICID®. 
Mining the shucks whichenvelope the nuts, causing them tobe abortive and many to 
fall from the tree prematurely, a slender white sixteen-footed caterpillar about three- 
eighths of an inch in length. 
The moth is sooty black, the fore-wings with reflections of tawny yellow, blue and 
purple ; their outer edge black with oblique triangular whitish streaks placed at equal 
distances apart. A very oblique faint silvery blue streak extends inwards from the 
points of two of these white streaks, namely, the fourth and sixth ones from the tip 
of the wing; while the usual white spot on the inner margin of the wings is wanting. 
Expanse of wings, 0.60 inch. (Fitch.) 
76. THE HICKORY-NUT WEEVIL. 
Balaninus nasicus Say. 
Order COLEOPTERA ; family CURCULIONID&. 
A worm like the chestnut borer transforming into a long-snouted beetle closely like 
B. rectus, but with a darker, thicker, more curved rostrum, and with the antennz 
springing from its middle in the male and from its basal third in the female. Two
