lowish-white tarsi; middle pair like the anterior, except that there is a. 
white annulation near the middle of the femora; another at its articulation 
with the tibiae, and another near the base of the tibiae ; posterior legs. 
whitish, annulate with dark brown. (Dr. Clemens says nothing about the- 
markings of the legs and tarsi, but in his classification of his species by: 
the color of the tibiae, he places TES in the section “ without white 
tibiae.”) 47 ex. 17 inch. 
The larva may be found in the leaves of Eupatorium ageratowles 
from July to October, but is rather rare. The mine is at first a 
short narrow white line, but ends in a large tentiform mine. It. 
is on the under surface, and the larva frequently leaves one mine 
to form another. The maxillary palpi are a Æ#/e larger in this insect. 
than in Parectopa robiniella Clem. ; and I have not examined thg,neuration 
of this species, but I think it is en at a glance that they are congen-- 
eric. And I do not see how, with a species like this before him, Dr. 
Clemens could have placed robintella in a separate genus. In fresh speci- 
mens of robiniella the head is zof roughened. At p. 7, vol. 4, arte, I have 
suggested that Parectopa Clem. is simply Zeller’s section of Gracilaria 
with eight marginal veinlets in the primaries. Zeller’s section agrees nearly 
with Herrick-Schaffer’s genus, Euspilapteryx. And a glance at a figure of. 
Gracillaria (Euspilapteryx) amogattella, or G. (Eupilapteryx ) phasian-- 
ipinella, as figured by Stainton, Var. Hist. Tin., or the former in Woods’ 
Index Entomologicus, settles the position of Poe ectopa so far as the pattern 
of coloration can affect it. 
Many of the species of this genus, when very young, make linear 
mines. The mines of G. plantaginisella and G. eupatoriella are short, 
crooked lines, ending in the large tentiform blotches heretofore described.. 
That of G. salicifolieda is a narrow white line, sometimes nearly straight 
and with lateral branches on the underside of Willow leaves; when it: 
leaves this mine it again enters the underside, but passes immediately 
through to the upper surface, where it makes the large blotch mine. The 
statement at p. 20 aufe, that it makes but a single mine, is incorrect, as it. 
commonly makes two or three. The young larva is flattened, resembling 
somewhat a flat Lzthocolletis larva. G. purpuriella sometimes pupates. 
under a web, as stated an/e p. 28, but usually in its cone. The complete: 
cone sometimes occupies an entire leaf; the apex of the leaf is bent over,, 
so that the left edge touches the right one, to which it is fastened; then 
the leaf is rolled spirally to the base, and the tip is used to close one end 
and the base the other, so that the whole leaf is utilized. Many of the
