trating almost to the heart, and in them were found Enchodes sericea in 
the imago stage, although some of them were yet in the pupa case and 
nearly as soft and white as a pupa. 
These beetles belong to the family Melandryid, which contains a 
number of quite diversified genera that in general live on fungi or under 
bark. As far as their habits are known those living under bark do not 
seem to be injurious as borers, and whether we can consider this species 
as merely working in decayed wood or as a borer in green wood can 
hardly be decided by this one instance. © It is certain that the larve are 
capable of penetrating sound wood. 
The beautiful little Buprestid, Pecilonota cyanipes was reared from 
the aspen. When found, June 9, it was inthe pupa state in the axil 
between the body of the tree and quite a large branch. So much had 
been eaten around the base that the branch was already dead. Mr. 
Harrington reports capturing the species on a dead willow stump, and 
Mr. Fletcher a specimen on a dead aspen stump in Ontario. 
Galls made on branches of the willow, Salix discolor by Agrilus tor- 
pidus have been found quite common in certain districts near here, and 
in other districts was found Saperda concolor in galls equally as numer- 
ous. Inno case yet noticed have the two been found in close proximity. 
The galls made by the Buprestid are an oval swelling of the live branch 
very similar to the one made by the Saperda. Inside there is a dif- 
ference in the architecture of the home. While the Saperda remains 
- mostly within the swelling and makes its exit through it, the Agrilus 
bores an oval gallery downward from the gall, sometimes in the pith, 
but oftener indiscriminately through the wood, and makes its exit often 
an inch and a half below. The imago issued about a month later than 
the Saperda. 
From the Saperda galls were reared two species of parasites. One of 
these is Pimpla pedalis and the other belongs te the genus Bracon, 
which we have yet been unable to get named. . 
_Galls on the willow also yielded us a few specimens of the handsome 
Sesiid, Sciapteron tricincta, as named by Professor Fernald. The galls. 
did not differ in appearance externally from the others. Inside the gall 
a tunnel was made downward along the center for an inch. The whole 
cavity was lined with a soft, delicate, though very strong, buff cocoon, 
and undisturbed in this silken bed the larva passed through its trans- 
formations to the moth. 
From Hylesinus aculeatus, the Ash Scolytid, was reared a species of 
Bracon, pronounced by Mr. Ashmead as probably a new species. 
From a species of trefoil, Ptelea trifoliata, was reared a species of the 
Tineid genus Hyponomeuta. Wherever the shrub was found the thin 
white web was quite common early in the spring before the leaves were 
out. These webs were always at the terminal portions of the green 
shoots. The caterpillars, entering the stalk usually at the terminal bud, 
would bore down through the pith some three to six inches in the shoots
