nearly twice as large as that of the species; and having a white shell, with 
rounded prominences instead of angles. A century of cultivation, he says, 
would perhaps not advance the species generally to an equal degree of perfec- 
tion with this accidental variety. Fig. 1270. represents the Sphina juglandis, 
or Hickory Hawk Moth, which in Georgia is found on this tree. The cater- 
pillar is smaller than that of most of the other species, and generally is of a 
shaded red and yellow, though it is sometimes green. The perfect insects are 
brown, and resemble the English poplar hawk moth. The caterpillar buries 
in the ground, and varies very much as to the time in continues there: one 
observed by Abbott having gone into the ground in May, and reappeared in 
June; and another having buried itself in September, and remained in the 
ground till the following April. (Abdott and Smita, Insects of Georgia.)

Spec. Char., §c. Leaflets, in a leaf, 7—9; obovate-acuminate, argutely 
serrate; downy beneath. Fruit roundish, having 4 longitudinal ridges that 
extend from the tip to the middle, and 4 intervening depressions, or furrows. 
Husk dividing, from one extremity to the other, in the line of the furrows, 
into 4 equal valves. Nut subglobose, slightly compressed, having a long 
mucro at the tip, and a shorter stouter one at the base; yellowish. Bark 
exfoliating in long narrow strips. (Michr. N. A. S., Pursh Fl. A.S.) A 
native of North America, in fertile valleys in the Alleghany Mountains ; and 
flowering in April and May. Introduced in 1804. 
Description. Michaux says, speaking generally of the scaly-bark hick- 
ories, that “they exhibit many striking traits of resemblance which may 
warrant the grouping of them into a separate section. Besides their 
generic and specific characters, they possess others peculiar to themselves, 
by which they are so nearly related, that, were it not for some remarkable 
differences, they might be treated as a single species.” C. sulcata grows to 
the height of 80 ft., with an ample head, and a straight trunk. The bark is 
divided into strips, or shreds, from 1 ft. to 3 ft. long, the pieces of which, 
when they are ready to scale off, are warped outwards at each end, and attached 
only in the middle. When they fall, they are succeeded by others similarly 
exposed. In this species, Michaux observes, the plates of bark are narrower, 
more numerous, and of a lighter colour, than those of C. alba; from which 
differences he thought it advisable to give it the specific name of lacinidsa. 
The leaves vary in length from 8 in. to 20 in., and are composed of from 7 to 
9 leaflets; whereas in C. alba, the shell-bark hickory, the leaflets are invari- 
ably 5. The barren catkins are long, glabrous, filiform, and pendulous; 3 
being united on a common petiole, attached to the basis of the young shoots. 
The fertile flowers appear, not very conspicuously, at the extremity of the 
shoots of the same spring. They are succeeded by a large oval fruit, more 
than 2in. long, and 4 in. or 5in. in circumference. It has four depressed
