The pupa has never been described by comparison with related 
species. It is in most respects like that of the cabbage looper. 
A more detailed description of the moth has been given by Thomas 
in his fourth report as entomologist of the State of Illinois (9th 
Report, St. Ent., Ill., pp. 47, 48), which is quoted in Mr. Coquillett’s 
account, which was published in the Eleventh Report of the State 
Entomologist of Illinois, 1882 (pp. 38-43). 
DISTRIBUTION. 
The celery looper appears to be a Transition species, but it is fre- 
quently taken also in the Upper Austral region, where it breeds in 
certain localities, particularly westward. Possibly its being more abun- 
dant in cold climates will account for the scarcity of reports of injury. 
Smith reports its occurrence in Hudson Bay territory, Canada; in the 
United States east of the Rocky Mountains—Colorado at 12,000 feet, 
and New Mexico; also that it appears throughout the season. Our 
National Museum collection, with some other sources of information, 
shows the following list of localities in addition to those that have 
been mentioned above: 
Maine; Massachusetts; Rochester, Rhinebeck, and Poughkeepsie, N. Y.; Wash- 
ington, D. C.; Westpoint, Nebr.; Caney, Kansas; Merino Valley, New Mexico; Longs 
Peak, Colo.; Wisconsin; St. Louis, Mo.; Portland and Albina, Oreg. Several of these 
localities are furnished on authority of Dr. H. G. Dyar. In New York, in the region 
specified, he captured specimens on different occasions during the last week of July; 
in Oregon, during the second week of May. 
DIVISIONAL RECORD. 
There is a single divisional record in regard to the biology of this 
species. April 10,1893, we received from Mrs. J. 5. Maurice, Caney, 
Kans., a moth stated to have been observed on blossoms of apple. 
This had deposited eggs en route, and some larvee began feeding as 
soon as received. By May 2 they had nearly completed their growth, 
and the following day the first larva spun up. As it takes from one to 
three days for larve to transform, and the first moths did not issue 
till May 20, the pupal stage in this instance may be placed at fifteen or 
sixteen days. The larval stage during the same period was approxi- 
mately three weeks. Larve fed on weeds with which they were sup- 
plied, but as there is no evidence that these wefe natural foods their 
names need not be mentioned. 
We have no information as to any natural enemy of this species. 
REMEDIES. 
The same remedies advised for the cabbage looper would, of course, 
be applicable to this species when it occurs in injurious numbers. — It 
is necessary, however, that whatever remedy is employed be used 
also on wild food plants, including weeds, which this insect affects.
