Eighth Report of the State Entomologist. 205 



although not continuously. Circulation is still maintained by windins; 

 around and among the furrows; but one more season's work will, it 

 is believed, take the life of the tree 



In a row of maples bordering a lawn scarcely a single tree is entirely 

 exempt from injury — all apparently the work of this grub. If these 

 injuries are to continue and increase, and I see nothing to prevent it, 

 our maples, which we prize so highl}'-, will share the fate of the 

 locust and be abandoned to the borer as too unsightly a tree 

 for ornamental use. 



The " beautiful Clytus " is a difficult insect to control, and very 

 many of the fine old maples, which have oi-namented our streets and 

 afforded us so agreeable shade, have been or are being killed by it. A 

 few years ago it was a source of much pain to me to see at Benning- 

 ton, Vt., the large number of old maples that were standing dead upon 

 the streets or rapidly dying from the merciless burrowing of this borer 

 that had scarred and excavated their trunks. Recently the same 

 ravages, although not as yet to the same extent, were observed by me 

 at Glens Falls, N. Y. 



Probably the best method of arresting the ravages of this pernicious 

 borer wotild be to Avatch for the commencement of the operations and 

 kill the young larva. The eggs are laid in July and August, [The 

 means communicated to the lady for finding and killing the borer were 

 virtually the same as those given in the reply to Mr. Her rick, and 

 therefore need not be repeated here.] 



The Squash-bug, Anas a. tristis (De Geer), 

 A correspondent desires to know what is best for the destruction of 

 the black squash-bug, Anasa tristis. Can Paris green be used with 

 safety ? If not, what can be used quickly and safely on an acre or two 

 of squashes ? 



Paris green is of no service against the squash-bug, or the many 

 other bugs of the Order of Hemiptera that take their food through a 

 proboscis from the interior of plants. The 

 best remedies, so far as known at the pre- 

 sent, for the squash-bug are found in trap- 

 ping and killing the females before their 

 oviposition, and in the destruction of the 

 eggs. Some success has attended experi- 

 ments made for preventing attack, by the 

 employment of strong-smelling substances, 

 as for example, dipping corn-cobs in gas-tar 

 and thrusting them in the ground among fio. 46.- The squash-bug.-^ANASA
