5i8 REPORT OF NEW JERSEY STATE MUSEUM. 



M. palmii Hy. Edw. Probably occurs at Lakehurst and elsewhere in 

 South Jersey in red oak and scrub oak (Engelhardt). 



M. asilipennis Bdv. (Tarsa denudata Harr.) Morris Plains (Neum) ; 

 Paterson V, 30, Haledon, pupa found in oak stump, Milltown V, 30, 

 Maurer V, 16 (Gr) ; Newark V, 18 (Sb) ; Jamesburg V, 9 (Sm). Lanra 

 in red and white oak, mostly in stump cut the previous year. 



M. dollii Neum. (Sciapteron) Homestead, adults abundant end of May 

 (Wrms) ; Newark (Ang) ; the larva bores in the trunks of young 

 Carolina poplar, and the species probably occurs throughout the State. 



>GERIA Fab. (TROCHILIUM Scop.) 



XE. apiformis Linn. Newark, rare (Soc); the larva bores in the roots 

 and lower part of the trunks of Carolina poplar and willows. Mr. 

 Engelhardt says it is local, but thinks it should be found elsewhere 

 in New Jersey. 



>E. tibialis Harr. Riverton IX, 9, Brown's Mills IX, 15 (Dke). Bores in 

 the trunks of willow and poplar. 



BEMBECIA Hbn. 



B. marginata Harr. Throughout the State, 

 locally and seasonally common, VI, VIII, 

 IX. The larva is the blackberry crown- 

 borer which sometimes causes consider- 

 able injury in the southern section. It 

 can be cut out, if sought for when the 

 shoot first begins to wilt. 



PARHARMONIA Neum. 



P. pini Kell. Ft. Lee, abundant in pitch balls 

 on white pine and spruce; at Lakehurst on 

 pitch pine (Engelhardt). 



SANNINOIDEA Beut. 



Fig. 221. Bembecia mar- 

 ginata: a, male; b, 

 female. 



S. exitiosa Say. Common, VI-IX wherever 

 the peach grows in New Jersey. The 

 larva is the well-known peach borer, which attacks the trees 

 at or just beneath the surface of the ground and often kills 

 young trees. These borers may be cut out in spring and fall, or the 

 trees may be protected by wire-netting, newspaper, or a wash of ce- 

 ment, lime or other mechanical covering that extends two inches be- 

 low and eighteen inches above the surface. The larva has also been 

 found feeding in willow (Bt, Ang). The variety "edwardsii" Bt. oc- 

 curs at Westville (Jn).
