Grateful acknowledgement is hereby made to these author- 
ities for their kindness, and to Mr. H. J. MacAloney and Dr, T. 
C. Barnes for permission to incorporate a part of their unpub- 
lished lists of incidental fauna from the same type of material, 
twelve and two species respectively. Species bred out by these 
investigators will be so noted. All localities, if not otherwise 
stated, are Boston, Mass, and environs. 
It should be made clear that the following several classes are 
definitely excluded from this list: 
1. All parasitic Hymenoptera, whether parasites of Pissodes 
sir obi or otherwise. 
2. Several predacious Clerids, one fly definitely known to 
be connected with the white pine weevil, one fly erroneously con- 
nected with the weevil in the literature, and one lepidopteron 
which is facultatively predacious upon Pissodes. These two 
classes are reserved for another and more extended paper. 
3. All insects known to work in these leaders but not ob- 
tained, e. g.j the pine tip moth, Rhycionia frustrana, the pine- 
bark aphid, Adelges pinicorticis, A. pinifolice, Pissodes affinis, P. 
approximatus, Hylobius pales, et al. The white pine weevil, it- 
self, was not obtained from the breeding room or the cages, al- 
though rarely, living adults may emerge after hibernation in the 
pupal cell. 
It is realized that this miscellany is not a complete list of 
the arthropods associated with weeviled leaders, but it is believed 
that it comprises a fair representation of those forms which more 
or less regular^ live or hibernate in such shoots. 
In the opinion of Mr. J. H. Emerton, all of the following 
spiders, except Agelena ncema, were very probably from no source 
Class Arachnida
