UNPUBLISHED OFFICE NOTES.

June 5, 1879, we received from Mr. William Trelease, then at 
Dawson, Ala., larvae found feeding on cotton. June 12 a larva 
kept under observation changed to pupa, and on June 20 tin- moth 
issued, this individual having passed 14 days as pupa. The same 
year the moth was reared on several occasions from material obtained 
on red clover in the District of Columbia by Messrs. Pergande and 
Howard. June 28 the moth issued from the pupa. August 15 the 
larva was observed feeding; changed to pupa August 25, and issued 
as moth March 1 of the following year. August 29 the larva was 
observed feeding: changed to pupa September 4. the moth issuing 
March 22 of the next year. 
February G, 1880, we received from Lake Bearsford, Fla.. from 
Prof. J. H. Comstock, a larva obtained on orange. 
There are also reared specimens of moths in the U. S. National 
Museum bearing labels showing the rearing of moths and occurrence 
of larva? on different plants, as follows: On locust, May 6, 1893, 
District of Columbia : hickory, November 24. 1804. Cadet. Mo., and 
August 4 of the same year on pear, locality presumably the District 
of Columbia. There is also a specimen labeled ** on guava." proba- 
bly from Florida. 
August 6, 1004, specimens of this spanworm were received from 
Calhoun. Ala., where they were found feeding on cotton and were 
mistaken for the cotton leaf-worm (Alabama argillaeea Hbn.). The 
adult issued August 20. Larva 1 were about full-grown when received. 
August 0. and it seems probable that they underwent a short -tage 
of aestivation before transforming to pupae, as the pupal stage is less 
than 20 days in midsummer. 
During the first two weeks of October for several years larva 1 have 
been observed on asparagus grown in the District of Columbia, the 
species appearing in moderate numbers. The first moth that has 
been reared from October-collected larva 1 appeared in January, and 
others appeared in February. As this was in confinement the dates 
were not natural ones. 
LIST OF FOOD PLANTS. 
It is, as previously remarked, owing to the omnivorous habit of this 
species, causing a distribution of attack, that noticeable injury has 
not been ascribed to it elsewhere than in cranberry bog-. It is com- 
mon enough in the vegetable and truck garden, but not confined to 
any particular place on the farm, occurring in orchards, on forest 
and shade trees, and on other plants. The li-t of observed i'ood plants 
include- asparagus, strawberry, blackberry, ornamental geranium, 
apple, pear, orange, willow, hickory, cranberry, honey Locust, cotton, 
clover, and guava. As a rule the larva 1 confine themselves to the
