THE INSECTS OE NEW JERSEY. 



463 



P. duovata Bird. The larva bores in the golden rod, "Solidago semper- 

 virens," and will probably be found where this plant occurs. 



P. impecuniosa Grt. Stalen Island, the larva in "Aster puniceus" (Ds) ; 

 aster and helenium are general food plants according to Bird, and 

 the species probably occurs throughout the State. 



P. inquassita G. & R. Hopatcong (Pm) ; Elizabeth IX, 30 (Bz); Staten 

 Island (Ds) ; August and September. The larva in the roots of sen- 

 sitive fern (Bird). 



P. speciosissima G. & 11. Ridgewood VIII, 30; Newark (Soc); Elizabeth 

 X, 1 (Bz). A rare species, whose larva has thus far escaped detec- 

 tion. 



P. frigida Sm. The larva lives in the meadow Rue, and no doubt occurs 

 in New Jersey. 



P. sciata Bird. Newark IX, 5 (Sb); Elizabeth X, 5 (Bz). and probably 

 elsewhere in the State. The larva bores in "Veronica virginica," 

 and this is the species listed as "limpida" in the previous edition. 



P. cerussata Grt. Newark IX, 28 (Sb); Staten Island (Ds). The larva 

 bores in iron weed and probably occurs wherever that plant grows. 



P. nitela Gn. Throughout the 

 State and sometimes 

 common. The normal 

 food plant is the rag- 

 weed, "Ambrosia trifida," 

 but it may infest dock 

 and other of the weedy 

 plants. Sometimes it be- 

 comes excessively abun- 

 dant and then attacks 

 potato, tomato, aster, 

 dahlia, corn and a great 

 variety of other plants, 

 causing local injury. 

 Gardens and small plant- 

 ings are most generally infested, and as a rule where they adjoin a 

 weedy road or field. Adults occur from late July to September, and 

 a good general measure to prevent trouble is to keep down the rag- 

 weeds by mowing in early July. 



P. duplicata Bird. The larva breeds in horse balm, "Colensonia cana- 

 densis," and will almost certainly be found in the State. 



P. imperturbata Bird. Bores into the stems of the wild sunflower, "Heli- 

 anthus divaricatus," and should occur in New Jersey. 



P. necopina Grt. The larva bores in the stalks of the wild sunflower, 

 "Helianthus giganteus," and the species will no doubt be found there 

 whenever sought for. An adult is very rarely taken even where the 

 larva is abundant.'
