Length of the female 6-10 mm. 
Of 16 dated specimens of the male 
in my collection, 12 were taken in 
October or November, and 4 in March 
or April. The two spring specimens 
in my collection now are among the 
most strongly characterized I have. 
Of several hundred females in my 
collection, four were taken in April 
and the rest in November.

[April 28, 
Length of the female 5-8 mm: 
Of 16 dated specimens of the male 
in my collection, 1 was taken in 
March and 15 in April. 
Of nine females in my collection, 
all were taken in April. Among sev- 
eral hundred females of A. vernata 
taken in November I do not find one 
female of this species, wherefore [| 
think it probable that this species is 
found only in spring. 
I must acknowledge myself indebted to Mr. H. K. Morrison for 
the suggestion that I should find A. vernata a fall species and A. pom- 
etaria a spring species. It seems as if the occurrence of A. rernata 
in spring might be explained by considering the spring specimens as 
belated. The necessity of applying the name vernata to a fall spe- 
cies illustrates the danger of attempting to give names characteristic 
of season or locality. 
I hope observers will take note next spring whether the eggs of A. 
pometaria do not want the jug-like shape and lid-like upper end 
which are seen in the eggs of A. vernata, also whether the eggs 
are not laid separately in chinks of bark, and whether their num- 
ber is not about sixty, instead of over two hundred, as in A. ver- 
nata. I have only seen apparently immature eggs in the female.! 
Dr. Hagen exhibited a book from a library at Beaufort, 
N. C., which was ruined by white ants (Zermes flavipes). 
Dr. Hagen also stated that he was engaged on a revision 
of the North American Phryganide, and gave the following 
list of species to illustrate the northern distribution of the 
sub-family. 
Sub-family PHRYGANIDZ. 
Neuronia. 
1. dossuaria Say (Limnophilus dossuarius Hag. Syn.). N. England. 
2. concatenata Walk. (irrorata Hag. Syn.). New England. 
1A few days after the presentation of the above communication Mr. Morrison 
informed me that he had lately seen a female A. pometaria thrust her ovipositor 
in between the chinks of bark of the apple-tree, and lay anegg there. He pulled 
off the bark and found eggs beneath. He had also seen the female thrust her ovi- 
positor into the crack of a board fence, and lay anegg there. He did not observe 
the shape of the egg.
