THE INSECTS OF NEW JERSEY.

ALBUNA Hy. Edw. 



A. pyramidalis Wlk. Sure to occur in North Jersey (Engelhardt) . 

 A. fraxini Hy. Edw. (Parharmonia) "New Jersey," the larva in ash 

 (Bt). 



SESIA Fab. 



S. bassiformis Wlk. Carlstadt, larva very abundant in iron weed (En- 

 gelhardt); Staten Island VIII (Ds) ; Merchantville VIII, 27 (Kp) ; 

 Riverton VIII, 17 (Dke). 



S. tipuliformis Linn. G. d., flies in VI, VII. The larva is the common 

 currant borer, and I have found it or its work in all parts of the 

 State. Where it occurs in harmful numbers, cutting out and destroy- 

 ing the infested canes is the only remedy. 



S. bolteri Hy. Edw. Paterson, in the stems of willow, "Salix concolor" 

 (Engelhardt). 



S. pictipes G. & R. Garret Mt, Paterson VI, 2, larva in chestnut (Gr) ; 

 Staten Island VI, VII (Ds) ; Elizabeth VII (Bz) ; New Brunswick, 

 Riverton, Hammonton (Coll); Wenonah V, 30 (Dke). The larva 

 bores in the trunks and branches of plum, cherry, peach and chest- 

 nut, but rately does marked injury. 



S. albicornis Hy. Edw. Morris Plains (Neum) ; Ft. Lee, Paterson (En- 

 gelhardt) ; Newark V, VI (div) ; the larva in willow galls and some- 

 times in Carolina poplar. 



S. acerni Clem. Throughout the State; V- 

 VII. The larva bores in the trunks of 

 maples and sometimes ruins the younger' 

 shade trees; it is much more common, 

 in my experience, in the more southern 

 sections. 



S. corni Hy. Edw. Hopatcong VII, 4 (Gr) ; 

 Staten Island VI (Ds) ; Elizabeth VI, 

 VII (Bz) ; the larva in maple. Mr. En- 

 gelhardt finds it quite common locally, 

 on city trees, and says that it affects the 

 branches rather than the trunk. 



S. pyri Harr. Occurs throughout the State 

 VI and VII. The larva infests apple, 

 pear and mountain ash, and is some- 

 times locally abundant, favoring apple 

 as a food plant. It has never been 

 really harmful in my experience. 



S. scitula Harr. Paterson V, 25, Jamesburg 



VII, 4 (Gr); Wenonah VII, 15 (Haim) ;Fig. 222. Sesia acerni: a, larva; b, 



DaCosta VI, 3 (Dke) ; breeds in and un- cocoons in cavities made by 

 der the bark of oak, chestnut and hick- larvae; c > moth; d - pupa '
