The Woolly Alder Aphis.—In the current report of the New 
Hampshire Experiment Station observations are recorded by Clarence 
M. Weed which show that in autumn large numbers of the young of 
this species (Schizoneura tessellata Fitch) are born by the partheno- 
genetic females. These young descend the alder shrubs to the surface 
of the ground, where they congregate, under various sorts of shelter, in 
enormous numbers. They remain there throughout the winter, and in 
spring those which have not been washed away or otherwise destroyed 
climb up the trunk to the limbs, where they fix themselves on the 
lower surface of the bark and grow rapidly into other parthenogenetic 
females. No males, females, or eggs have been found. This insect 
has been very abundant in New England during recent years; the 
appearance of an infested branch is shown in the accompanying plate. 
Further Note onthe Tineid Case-worm from the Grand Can 
yon—lIn my description of the seed-like lepidopterous case-worm from 
the Grand Canyon in the February, 1893, number of Tar NATURALIST, 
pp. 166-169, figs. 2 and 3, it should be mentioned that the hair line in 
fig. 2 shows twice the natural size of the larva. Fig. 2 was intended to 
be reduced one-half, and was so indicated on the margin of the original 
drawing. The hair line was made twice the length of the larva, so 
that when the whole was reduced one-half it would represent the nat- 
ural size, stated in the description as 2¢ mm. 
It seems very certain that this larva is a tineid. It is well-known 
that these small larvz often construct cases in which they live; and, 
as Dr. Packard states (Guide, p. 342), the larve of some of the 
smaller tineid genera (Antispila, Tinagma, etc.) are absolutely footless. 
The narrow-leafed willow referred to in the description is Salix 
longifolia Muhl., while the round-leafed leguminous tree is Cercis occi- 
dentalis Torr. The elevation of that part of the canyon referred to as 
2500 ft. below the rim is 5000 ft. above sea level.

The Puparium of Blepharipeza.—Blepharipeza i is a genus of 
Tachinidæ s. str., belonging in the subfamily Hystriciine, and thus 
closely allied to Dejeania and the other Tachinidæ that are character- 
ized by the presence of dense and spiny macrochaetæ on the scutellum 
and abdomen. Blepharipeza may at once be recognized in this group 
by its hind tibiæ being pma ciliate on their outer oe) with more 
or less flattened brist
