REMEDIES AGAINST TERAS OXYCOCCANA. 25 
of the Anchylopera in habit and general appearance; the head and neck, 
however, are honey-yellow instead of black; the body is of a somewhat 
paler green, and the larva when full-grown is larger—nearly half an 
inch in length. The head is nearly as wide as the first segment; and the 
body tapers gradually to the tail, and is furnished with fine, sparse, pale 
hairs. arising from prominent tubercles; the four dorsal tubercles are 
arranged in a trapezoid with a deep crease between the anterior and 
posterior pair; the anterior three pairs of feet are tipped with black. On 
each side of the base of the head is a lateral, S-shaped, blackish-brown, 
linear band, the upper part of the S terminating on the top of the occi- 
put, the line being most distinct on the side of the head. The ocelli are 
black. The pupa is brown, rather slender, and has the head prolonged 
into a large tubercle surmounted by a large, round and roughened knob ; 
there is an angular projection on each side of the head, forming a shoulder 
to it. ‘‘The wing-covers reach to the end of the third abdominal ring, 
while the antenne reach to the end of the second pair of feet, which are 
parallel to the end of the second abdominal ring. There are two rows of 
teeth on the upper side of the abdominal rings; they are obsolete beneath, 
the posterior row being indicated by two remote, minute tubercles.” Itis 
about two-fifths of an inchlong. Thereis noappreciable difference in size 
between the larva of the gray or winter form and that of the summer 
form, but the pupa of the latter is rather smaller. 
ENEMIES. 
Unlike the Anchylopera, which appears free from insect enemies, this 
insect is preyed upon by two parasites: a dipterous larva belonging to 
a species of Tachinid and the larva of an Ichneumonid.* 
These parasites I have found in the second brood only; all my larve 
of the first and third broods completed their changes, while those of the 
second brood were almost all infested with parasites, and these I appre- 
hend will do much to prevent this species from becoming as plentiful as 
the Anchylopera. 
REMEDIES. 
A bog that can be completely Howed need never suffer much from this 
‘insect. All thatis necessary is to keep the water on in the spring until 
after May 1. By that time the surviving moths will either have per- 
ished without depositing eggs at all, or they will be compelled to de- 
posit them on the apple trees or whortleberry bushes; the latter being 
probably their original food before the abundance of cranberries enticed 
them to the bogs and led to their rapid increase. This remedy has 
* None of the specimens of the Tachinid bred by Mr. Smith had the wings developed, and all were 
otherwise so shriveled and imperfect that determination is impossible. The Ichneumonid is Macro- 
centrus delicatus Cr., figured in our Fifth report on the insects of Missouri as parasitic on the Apple 
Worm (Carpocapsa pomonella). It is an interesting fact, as bearing on the unity of habit in the same 
genus, that we have likewise reared Macrocentrus from two other Tortricids, viz,, Grapholitha cary- 
a@ana Fitch and Tortriz paludana Rob.——C. V. R.
