immaculate. Surface finely wrinkled transversely, but without pilifer- 
ous warts or pubescence. Head small, round, amber-yellow with dark- 
brown, triangular or V-shaped spot on each side. Anal plate orbicular, 
slate-gray. Thoracic legs same color as general surface; prolegs im- 
perfectly developed. It bores from the tips of the shoots downward 
for an inch and a half or two inches, devouring everything but the 
cuticle and packing the frass at the upper end. When full grown it 
makes its exit through a round hole which it cuts at the lower end of 
its burrow, and, entering the earth, incloses itself in a tough, silken 
cocoon, in which it remains dormant until the following spring. The 
single fly which I have thus far succeeded in rearing issued in May, and 
is of the same size and very similar in appearance to the common Rose 
Slug fly (Selandria rosew). Professor Riley says of it that “it appears 
to belong to the genus Ardis of the Selandriide.” 
Climbing Cutworms were a prominent feature of the entomological 
developments of the spring. These attacked the Oaks, Elms, and other 
Shade trees, as well as Apple, Pear, and Cherry trees and a variety of 
vines and shrubs. Among the species detected in their work of de- 
struction were Agrotis saucia, A. scandens, A. alternuta and Homohadena 
badistriga. The grass under shade and fruit trees would often in the 
morning be thickly strewn with leaves and buds that had been severed 
during the night. This was especially noticeable under the various 
Oaks and Sweet Cherries. On a large, isolated specimen of the latter, 
up which a Trumpet vine had climbed, I took early in May a great 
number of the larvie of Agrotis alternata. These mottled gray worms 
were found during the day extended longitudinally on the trunk, closely 
appressed to the stems of the Trumpet vine, where, protected by their 
imitative coloring, it would be impossible for an unpracticed eye to de- 
tect them and where even birds failed to find them. When ready to 
transform they descended to the earth and inclosed themselves in an 
ample, tough, dingy-white cocoon, under any slight protection that 
might be convenient. I also took this species from crevices of oak- 
bark and occasionally found one feeding in a rose. 
Canker Worm (Anisopteryx vernata, Peck).—Not for several years has 
this pest appeared in such numbers in the orchards of this locality 
as during the past spring. Nor did the apple trees seem to recover 
from the excessive defoliation during the remainder of the season. The 
worms were especially numerous on trees around which the soil had 
not been stirred for a year or more. 
IT noted this year a habit of this insect that has not, to my knowl- 
edge, been previously recorded, viz, that the worms, with great regu- 
larity, desert the leaves during the middle of the day and hide in the 
forks of the branches and on the trunk in crevices and under loose 
scales of the bark. As TI did not at once discover this propensity in 
these larvie, it puzzled me for some time to account for their secarceness
