INSECTS AFFECTING PARK AND WOODLAND TREES

Balsam gall midge 



w. Cecidomyia bahamicola Lintn. 



A small midge produces an oval enlargement near the base of balsam needles. 



This insect was first brought to the late Dr Lintner's attention in 1886, 

 because of its abundance on balsam fir in Adirondack localities. It does 

 not appear to occur in the vicinity of Albany, though it has been taken at 

 Shelbourne N. H., and specimens of what appears to be the same insect, 

 were received by Dr Lintner from North Carolina, where they infested the 

 southern balsam, Abies fraseri. Occasionally this insect is so abun- 

 dant as to give a peculiar nodose appearance to affected trees, at which 

 times as many as three quarters of all the leaves may be infested. The 

 larvae are inactive, hardly move and show no disposition to feed. Badly 

 infested trees lose a considerable portion of their foliage in December, all 

 the galls dropping. The adult has not been reared so far as known. 



False chinch bug 



Ny sins angustatus Uhler 



A small, grayish and brown plant bug 3/ l6 inch long 

 occurs on a variety of plants. 



This species is best known on account 

 of its being confused with that notorious enemy 

 of the farmer, the chinch bug, B 1 i s s u s 1 e u- 

 copterus Say. It is a general feeder, occur- 

 ring on such diverse plants as appletrees, hard 

 pines, grapevines, potato vines, turnips and 

 radishes. 



Phytocoris eximius Reut. 

 This is an inconspicuous, brownish marked 

 Capsid (fig. 204), a little less than ^ of an inch 

 long. It occurred somewhat sparingly on hard pine at Karner in Septem 

 ber, 1901.
