CEDAR WORMS. 919 
attached to the twigs of the tree, can not be mistaken for anything else. 
Many of these contain the eggs, which remain throughout the winter 
and hatch in the following May. They may consequently be removed 
and destroyed by hand in the winter and spring, or the trees may be 
protected by spraying with Paris green or other similar poison in June 
or July, when the worms are eating the leaves. (Forbes 7 First Keport 
Ins. Illinois.) 
3. Eupithecia miserulata Grote. 
We have found the caterpillar on the cedar August 30, 1883. It pu- 
pated September 29 to October 1, and the moth appeared May 12 of the 
following year. 
Larva. — Body slender, sutures well marked. Head small rounded, not bilobed, not 
so wide as the body. Uniformly pale green, being exaetly concolorous with the 
leaves. No humps or warts, the sutures marked with yellow, while the lateral 
ridge is marked with greenish yellow, forming a prominent interrupted greenish 
yellow lateral line. Supra-anal plate very short, smooth, obtuse at apex, the edges 
marked with greenish yellow. Anal legs thick and short, not broad. No dorsal 
spines. Length 12 mm . 
Pupa. — Body slender, of the usual form; green. 
4. The fir saw-fly. 
Lophyrus abietis Harris. 
False caterpillars closely resembling those found on the fir, and iden- 
tical with that found on the low-bush juniper, occurred on two cedar 
hedges in Brunswick, from July 18 to the last of August. But a few 
scattered individuals occurred. We will give a description of the variety 
found on the cedar. 
Body cylindrical, broadest on the thoracic segments; all the segments finely trans- 
versely wrinkled. Head small round, deep, amber-colored ; eyes black. Body pale 
green with a broad diffuse dark green medio-dorsal and a lateral stripe. Body paler 
beneath. Thoracic feet black. Eight pairs of abdominal feet green. Length 13 mm . 
One was found without the three dark stripes. This species differs 
from the others in the caterpillar having no dark spots on the body as 
seen in most Lophyrus larvae. 
5. The promethea moth. 
Callosamia promethea (Drury). 
Said by Mr. Riley to feed on the arbor vitse. (Fourth Rep., 123.) 
6. Ematurga faxonii Minot. 
Professor Riley has reared this moth from caterpillars found on the 
arbor vitse. It also occurs on the cranberry. 
7. Xoctuid ? larva. 
This caterpillar was observed at St. Augustine, An astasia Islands, 
on the common red cedar, April 14. The specimens were probably 
immature.
