tratiug 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 Melandryidie, 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 larvae are 

 capable of penetrating sound wood. 



The beautiful little Buprestid, Poecilonota cyanipes was reared from 

 the aspen. When found, June 9, it was in the 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 b^^ Agrilus tor- 

 pidus have been found quite comuion in certain districts near here, and 

 in other districts was found Saperda concolor in galls equally as numer- 

 ous. In no 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 to 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 galll 

 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 Eyponomeuta. 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 termiual 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
