A CONTRIBUTION TO THE MORPHOLOGY AND BIOLOGY OF INSECT GALLS. 

 By A. Cosens, M.A. Reprinted from the Transactions of the Cana- 

 dian Institute, Vol. IX, pp. 297-387, 1912. University Press, Toronto; 

 13 plates. 



This paper, both botanical and entomological in its character, de- 

 scribes investigations carried on in the Botanical Laboratories of the 

 University of Toronto under the supervision of Prof. J. H. Faull. 

 Only its entomological results are dealt with here. The anatomical 

 and histological structure of galls produced by 8 species of Acarina, 

 8 Aphididae, I Psyllid, i Sesiid, I Tortricid, 2 Gelechiids, i Tineid, 

 12 Cecidomyidae, 10 Nematinae, and 24 Cynipidae are described; the 

 order in which they are treated Acarina, Hemiptera, Lepidoptera, 

 Diptera, Hymenoptera corresponds in a general way with an increas- 

 ing complexity in the galls. 



In dealing with the Lepidopterous galls attention is called to "the 

 highly specialized habits of the larva, developed in caring for the 

 welfare of the imago Thus in each of the forms studied pro- 

 vision is made by the larva for the emergence of the moth from the 

 gall. These habits are seen at different stages of development. In 

 Stag mat ophora ceanothiclla Cosens, and Eucosma scudderiana Clem-
