the vicinit\- of wounded arras on tlic trunk, and that the)- cannot penetrate 

 the (lulcr hark of niher than lender trees or the Ijranches of larger trees. 

 He found gaUeries of the insect in botli the trunk and branches above and 

 behjw the whorls, and states that sometimes the borers completely girdle 

 the stem anil kill the portion abo\c. The work described by Dr Kellicott 

 was (]uite (.liflerent from that observed by us at Karner and it may be that 

 two species have liecome confused. A thin, papery cocoon is spun in July, 

 as stated l>y Mr Grote, and the moth appears lo to 14 days later. We ha\e 

 l>red it the latter i)art of July. 



Food plants. Mr Charles Zimmerman, for whom this species was 

 named, n-cords it on the followir.g pines: PInus s t r o b u s, P. rubra 

 or P. r e s i n o s a, P. a u s t r i a c a, P. s y 1 v e s t r i s, P. c e m b r a and on 

 the Corsican, lofty liothan aiul Russian i)ines. He states that P i n u s 

 s \T V e s t r i s seems to suffer most, as the limbs and even the main stems 

 are constanth' breaking oil. Ihr hard [)ine, Pin us r e s i n o s a, is the 

 common species at Karner, ami we have )'et to hnd the insect appearing on 

 an\' other and in a manner dilierent from that described above. Conse- 

 (pientl)', we are at a loss to account for its wide range of food p^ilants and 

 \er)- different methoil of work noted by earlier writers, unless there has 

 l)een a change in lo(_)d habit or two species are under consideration. 



Injuries. Dr Kellicott, writing of this insect in 187c), states that many 

 small pines at Hastings, Oswego co. were seriousl)- infest(jd, and Professor 

 Grote e.xpressed the belief the same }ear that this insect causetl more 

 injur}' to \()ung white pines than an\' other species. 



Distribution. Dr Kellicott lound this species at Buffalo, Cheektowaga, 

 1 lamburg and Clarence', lirie co. ami Hastings, (Jswego co. He also found 

 it common in both cultivated and forest pines at Corunna Mich., it being 

 especially elestructixc to small ornamental pines and spruces in a cemetery, 

 lb.; took eight pupae Irom the trunk o( a single spruce. 



Parasites. A |)arasite was found b\- Mr Grote filling the cocoons of 

 this insect, and I )r Kellicott records the presence of this l)eneficial species 

 in localities where the moth is abundant. He also bred another parasite 

 from this insect but has not reconled its name so far as known.
