G. spiraeae^ G. alni, G. decora, G. perplexa, probably G. vihurni, Mo-

 Sermyl<issa haleihsis and AgeloHtica alni) or the pupation takes place 

 above the soil. In some of the species whose larvae pupate above 

 the soil the pupa is rather unprotected and found loose on the ground, 

 in small crevices, under pieces of wood, etc. {Galerucella luteola) or 

 it is attached to a leaf by the end of the abdomen {GaleruceUa 

 on/mphaeae, G. Ihieola), or the pupa is encased in a cocoon with a 

 reticulate wall fastened to a leaf {Galerucella notata, Galerucella 

 cribrata) . 



Literature. — The latest list of literature concerning Galerucinae 

 larvae is found in a Danish book entitled " Victor Hansen : Biller 

 (Chrysomelidae og Lariidae) 1927." The list is given on pages 390- 

 395, at the end of a chapter, written by K. L. Henriksen, on the 

 larvae of the Danish Chrysomelidae and Lariidae. The publication 

 is No. 31 of a series of faunistic manuals, called Danmarks Fauna, 

 which are edited by the Danish Society of Natural History and pub- 

 lished by G. E. C. Gad, Copenhagen, Denmark. Keferences to Hen- 

 riksen's descriptions in this manual will in the following pages be 

 given as " 1927, Henriksen, K. L., Danmarks Fauna No. 31." 



Another publication with many bibliographical notes and impor- 

 tant descriptions to which reference often will be made is by Wil- 

 liam Colcord Woods. It constitutes Part 2 of Bulletin 319, from 

 Maine Agricultural Experiment Station, Orono, University of Maine, 

 1924, and deals with tlie blueberry leaf beetle and some of its rela- 

 tives. It will be referred to in the following as " 1924, Woods, W. C, 

 Maine Agr. Exp. Sta. Bull. 319."
