58 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
tiles** appendages and hiding them from view is a brush of black hairs, forming a con- 
ical tuft at th«- end of tin- abdomen, blunt at its apex. The h-tjs are more or less 
denuded of stales, blaok ind shining, with the hind shanks thicker toward their tips 
and with two pairs of spurs, the forward shanks having only a tingle spine, which is 
placed on t he middle of their inner sides, the same as in ot her mot hs : and the feet are 
oomprested and five-jointed, with the basal joint longest and the following ones suc- 
!y shorter. The /wi to i mfi are blaok, with groups of whitish scales forming 
gray -pots of clouds which are netted with black lines, varying greatly in different 
individuals. Often a transverse gray spot is situated toward- the base and another 
on the anal angle, the outer and hind margins being gray alternated with black. The 
hind wiiH/.i are black, with their posterior half of a rich marigold yellow color bordered 
with a black line upon the hind margin, the yellow color being irregularly notched 
on its anterior 3ide and narrowed to the inner angle, and not extended to tbe outer 
angle, the two outer cells being black. Tbe outer or anterior margin, except at its 
base and tip, is usually gray alternated with transverse black streaks and blotches, 
and iuside of this is a large ash-gray spot occupying the outer anterior part of the 
disk. The under sides of both wings are similar to their upper surface. 
The ft male would not be supposed to pertain to the same species with the male, her 
size is so much larger, her colors so much paler gray, and her hind wings being wholly 
destitute of the bright yellow coloring which forms so conspicuous a mark in the 
other sex. The branches of her antenme are also shorter, being but about four times 
as long as thick. The ground color of her fore wings is gray, variously netted with 
black lines dividing the gray in places into small roundish spots and into rings hav- 
ing black centers. The black color usually forms a broad irregular band across the 
middle of the wings parallel with the hind margin, and another between thisand the 
hind edge, chiefly on the outer half of the wing, the hind edge and fringe being whitish 
alternated with black spots placed on the tips of the veins. The hind wings are dusky 
gray and towards their bases blackish, their posterior half being freely transparent 
and faintly netted with darker lines. The body is densely coated with gray scales, 
its under side hoary white; and the legs are gray, with black bands on the shanks, 
and black feet, with gray rings at their articulations. 
Remedies. — We have but a single suggestion to make upon the subject of remedies 
against this truly formidable though fortunately rare enemy. It is probable that soft 
soap applied the fore part of June to the bodies of trees will be equally efficacious 
against this and other borers as it is against that of the apple tree. This remedy may 
well be resorted to, to protect the locusts and oaks which we value as ornamental 
trees; and scarce and valuable as timber is becoming in all the older settled sections 
of our country, I doubt not it will be found to be good economy to bestow similar 
attention upon the more valuable trees standing in our forests. 
It should also be observed that whenever a hole made by a borer is discovered in 
the trunk of a tree, it should be immediately closed by inserting a plug therein, to 
exclude the wet which will otherwise be admitted hereby to the interior of the tree 
and produce a decay of the surrounding wood. — (Fitch's Fifth Report, pp. 4-10.)

Prionoxystus qnerciperda (Fitch). 
Order Lepidoptera ; Family Cossid.e. 
(PI. ii, Figs. 4, 5.) 
Auother and rather smaller Cossid, but belonging to a closely allied 
species, was found by Mr. J. A. Liutuer resting upon the trunk of au 
oak tree in Schoharie, X. Y. It probably ranges all over tbe Eastern 
States and Mississippi Valley, since a species, either this or closely allied, 
is reported to us by Mr. G. W. Belfrage to inhabit central Texas. Dr.
