Habits. — Feeding on alder (Ahms), more rarely on hazel 

 (Corylus), skeletonizing and eating holes 'in the leaves ot" young, 

 one- to two-year-old pjants. Pupates in the ground just below the 

 surface. 



Literatwe. — 



Boas, I. E. V. 



19124. Daiisk Forstzoologi, 2(1 edition, p. 405. (The figure of a larva, 

 said to be Agelastica alni, does not fit tlie dt^scription given by Henriksen, 

 and is entirely different from the figure of this larva in the present paper. 

 Boas has not described the larva, only mentioned its color, size, and life 

 history.) 



Heneiksen, K. L. 



1927. Danmarks Fauna, No. 31, p. 350. (Henriksen's description agrees 

 with the figures and description of the larva in the present paper. As 

 mentioned above, these figures are made from a specimen originating 

 from the same old and probably not reared material in the Zoological 

 Museum of Copenhagen which Henriksen has studied ; but beside this 

 material new, and probably reared, material is preserved in the Copen- 

 hagen Museum, collected in 1894 by William Schlick. and 1895 by E A. 

 Rosenberg. With this material in his hands I consider Henriksen's de- 

 scription and the figures and description here published by myself as 

 correct and Boas' figure as made from a chrysomelid larva belonging to a 

 different genus.) 



TAXONOMY OF GALBRUCINAE LARVAE AND THEIR RELATION TO 

 HALTICINAE AND CHRYSOMELINAE LARVAE 



In the very valuable comprehensive treatment of the chrysomelid 

 larvae, the first of its sort in the world's literature, which K. L. 

 Henriksen has just published in Danmarks Fauna (No. 31, pp. 290- 

 376), the author writes, on page 314, that it is not possible to find 

 definite characters by which the larvae of the three subfamilies, 

 " Cyclici," " Galerucini," and " Halticini," -" can be grouped in the 

 same subfamilies as the imagines, and therefore he treats the larvae 

 of these subfamilies collectively. 



In a recent paper by myself -^ I have pointed out in a taxonomic 

 discussion (pp. 201-203) that by removing the tribes Diabroticini and 

 Phyllobroticini from the Galerucinae and placing them in the sub- 

 family Halticinae near the tribes S^^'stehini, Crepidoderini, and 

 Psylliodini it is possible to separate the rest of the larvae into the 

 same two subfamilies as the imagines. Again, judging from our 

 present knowledge, it is not difficult to separate the larvae of each of 

 these two subfamilies from the larvae of Chrysomelinae, as will be 

 shown by the following brief characterization of the three larval 

 tj'pes of the subfamilies in question. I therefore believe that in 



-"These terms, applied by Henriksen, correspond to thi> terms " Chrysoirtelinae," 

 " Galerucinae," and " Halticinae " used in the present paper.
