internally upon corn, tomatoes, beans, etc. Obviously we have in this 
species an external and an internal-feeding color variation. 
The smeared dagger (Acronycta oblinita S. & A.)—A larva three- 
tenths of an inch long, Washington, D. C., July 1,1897. The following 
day it molted and was kept for some time feeding on asparagus, but 
no attempt was made to rear it. 
The salt-marsh moth (Leucaretia acrea Dru.)—The caterpillar was 
brought to this office July 10, 1897, from Tennallytown, D. C., with the 
statement that it was feeding on asparagus at that place. September 
28 it was found upon asparagus at Marshall Hall, Md. 
Unknown measuring worm.—An unknown geometrid was several 
times taken feeding on asparagus and in different localities, but the 
species has not been reared beyond the pupa. 
A number of other lepidopterous larvie have been observed on aspara- 
gus by various persons, some of which havenever beenrecorded. Forcon- 
venience they will be considered together, and will only be brietly noticed. 
Zebra caterpillar (Mamestra picta Harr.).—*Injuriously abundant 
upon eabbages, asparagus,” etc. (Fletcher, Insect Life, Vol. V, p. 
125). Also Divisional Note. 
Clover Mamestra (Jamestra trifolii Rott.)—On asparagus in Europe, 
but not observed on this plant in America (Taschenberg, Prak. Insect- 
enkunde, Vol. III, p. 124). The European J. oleracea and pisi also 
occur on asparagus (1, ¢.). 
Black cutworm (Agrotis ypsilon Rott.),— Unpublished Divisional Notes. 
Noctua fennica Tausch.—Asparagus beds injured by it in Canada 
- (Fletcher, Insect Life, Vol. III, p. 247). 
Red-banded leaf-roller (Lophoderus triferana Walk.).—Reared by 
Miss M. E. Murtfeldt from asparagus in Missouri in 1883, (Divisional 
Notes.) 
PLANT-BUGS AND PLANT-LICE. 
Many species of hemipterous insects have been found upon aspara- 
gus, but the present list comprises only such as the writer is satistied 
actually feed upon this plant. 
The tarnished plant-bug (Pecilocapsus lineatus Fab.).—This ubiqui- 
tous capsid has been found on asparagus in nearly every locality visited 
and oceurs throughout a season. It is a most difficult species, in the 
writer’s experience, to detect in the act of attacking a plant, but from 
its numbers on asparagus it is more than probable that it subsists to 
some extent on this plant. 
Lopidea media Say.—May 30, 1897, numerous individuals of this cap- 
sid observed at Cabin John, Md., as many as four on a single plant. 
All the bugs appeared to be sucking up the juice of the asparagus with 
their beaks. A natural food plant of this species on which it occurred 
in the immediate vicinity of the asparagus beds where first observed is 
the common yarrow (Achillea millefolium), and the individuals observed 
ol asparagus were very evidently au overtlow from the wild food plant.
