The structure of the integument of the body and the development of the hairs vary, 
like the asperities of the locomotory warts, according to the environment. In Goes 
tessellatus the texture of the integument is tough, shining, and sparsely clothed with 
hairs; but these hairs are long, rather coarse, and distinctly colored brownish yellow. 
Anteriorly the dorsal side of the prothorax is smooth, and the hairs on its front 
margin do not form a continuous band as they do in closely related forms; posteriorly 
it is finely asperate. On the ventral side the posterior area of the prothoracic sternum 
carries a band of asperities which in this species is broken for a short distance in the 
middle. 
PUPA 
In West Virginia pupation has been observed to take place from April 
9 to April 15. The pupa is yellowish white and is capable of only feeble 
movement. With four individuals the pupal stage lasted 39, 41, 43, and 
44 days, respectively. 
DESCRIPTION 4 * 
The pupa measures about 25 mm. in length. As in all the longicorns, it bears 
considerable resemblance to the adult, and many characters are identically developed 
in the two stages. However, special pupal characters are found in the striking way 
in which the posterior half of the long antennae is rolled into a spiral below the abdomen 
and also in the shape, number, and arrangement of hairs or spines on many parts of 
the body. The hairs are yellowish brown and more coarse and well colored than in 
other species of Goes; they are rather numerous on the prothorax and are along 
the back of the first six abdominal segments set in two conspicuous longitudinal 
series of large blotches; each of the two blotches on the first abdominal segment 
contains about twice as many hairs as on the sixth segment. Finally, the last abdom¬ 
inal segment is armed with a well-developed, single, median process, which is conical, 
recurved, and mostly fleshy, but at the tip hardened into an acute and dark spine 
which laterally carries several minute teeth. 
distribution 
According to Blatchley, 6 this species is known from New York, Indiana, 
Louisiana, and Georgia. Its presence in West Virginia, which is central 
in the quadrangle of States mentioned, indicates that it may occur, 
locally at least, throughout much of the eastern portion of the United 
States where oak and chestnut trees grow. Notes in the files of the 
Bureau of Entomology show that the species has been observed in Vir¬ 
ginia and North Carolina. 
FOOD PLANTS 
By far the most extensive injury caused by the oak sapling borer is to 
white oak, Quercus alba , although the adult insects have been reared from 
chestnut oak, Q. primes , and injury probably attributable to this species 
has been noticed in other oaks. More rarely it attacks young chestnut 
trees, Castania dentata. In 1915 the writer obtained one beetle of this 
species among individuals of the roundheaded apple-tree borer, Saperda 
Candida Fab., reared from wood of young service trees, Amelanchier 
canadensis , collected in the woods. It seems that the insect is a general 
feeder, but with a decided preference for white oak.
