pencils, of tlie same color, directed backwards, on the elev- 
enth ring. The body is yellowish white, with dusky warts, 
and the head is brownish yellow. These caterpillars leave 
the trees towards the end of August, and conceal themselves 
in crevices of fences, and under stones, and make their 
cocoons, which resemble those of the hickory tussock ; and 
from the middle of June to the end of July the moths come 
forth. These moths are faintly tinged with ochre-yellow; 
their long, narrow, delicate, and semi-transparent wings lie 
almost flatly on the top of the back; the upper pair are 
checkered with dusky spots, arranged so as to form five 
irregular transverse bands ; the hind edge of the collar, and 
the inner edges of the shoulder-covers, arc greenish blue, and 
between the latter arc two short and narrow deep yellow 
stripes ; the upper side of the abdomen and of the legs are 
deep ochre-yellow. The wings expand about two inches. 
The name of this beautiful and delicate moth is LopJiocampa 
tessellaris, the checkered tussock-moth. It is figured and 
described in Smith and Abbot’s “ Insects of Georgia,” where, 
however, the caterpillar is not correctly represented. Mr. 
Abbot’s figure of the caterpillar has been copied in the illus- 
trations accompanying Cuvier’s last edition of the “ Regne 
Animal,” and is there referred to Latreille’s genus Sencaria. 
This includes, besides various other insects having no re- 
semblance to the foregoing, the true tussock caterpillars be- 
longing to the next group ; but from these the caterpillars 
of all the kinds of Lophocampa differ essentially, in being 
much more hairy, in not having the warts on the sides of 
the first ring longer than the rest, and in being destitute 
of the little retractile vesicles on the top of the ninth and 
tenth rings ; moreover, their chrysalids are not covered with 
short hairs in clusters or ridges. On the other hand, they 
agree with the Arctians in being covered with warts and 
spreading bunches of hairs, in rolling up like a ball when 
handled, and in the form and structure of their cocoons.
