Natural enemies. This species is apparently exempt from the attacks 

 of natural enemies. Messrs Riley and Howard record the rearing of 

 Trichacis rufipes Ashm. MS., from cocoons infested with this insect, 

 and Holcocera glandule 11 a Riley from St Louis Mo., and states 

 that this is probably from a Cecidomyiid inquiline. It thus appears that 

 no undoubted parasitic enemy has yet been obtained.

Chestnut weevils

Wormy chestnuts are familiar to all lovers of this favorite nut, though the parent 

 insects are not so well known as their unwelcome grubs. 



Chestnuts are so seriously infested by this insect in some seasons that 

 a large proportion of the crop is rendered worthless. It not infrequently 

 happens that a lot of chestnuts stored in some box or vessel soon after 

 gathering are found a few weeks later badly infested and sometimes nearly 

 entirely destroyed by the white grubs or young of this weevil. The 

 chestnut is a valuable native nut, and one which is apparently capable of 

 considerable development. There are now many acres in this and other 

 States almost unproductive which might produce large crops of this nut. 

 It is stated that great quantities of Spanish nuts are imported yearly 

 though equally good, if not better ones, can be grown here. Several indi- 

 viduals are now engaged in growing this nut for the market, and as an 

 illustration of what has been done, the 20 acres of bearing paragon trees of 

 Mr H. M. Engle, Marietta Pa., may be mentioned. Native trees were cut 

 on a steep hillside and the sprouts grafted to this improved variety, and in 

 about three years they began to bear. The trees were kept trimmed and 

 the ground clear from underbrush, and it was stated in 1896 that the land
