LARVAL FORMS OF COLEOPTERA 



rich ill material of European larvae wliicli has been acquired by ex- 

 change between Prof. C. V. Riley and Dr. Fr. Meinert at the Zoo- 

 logical Museum in Copenhagen or has been bought, particularly 

 from the collections of AVm. Schlick and K. AY. Verhoeff. 



Finally, the authors wish to extend their sincere thanks to Mr. 

 R. A. St. George. For a number of years he has been giving a great 

 deal of study to the larvae of the order, particularly the families of 

 the Cueujoidea, and has assisted in the characterization of this 

 series. At the same time he has made many of the drawings in- 

 cluded in this paper.
