A REVIEW OF HENRIKSEN S CERAMBYCID LARVAE IN 

 DANMARK'S FAUNA, BILLER III, TRAEBUKKE, 1914. 



Bi F. C. CRAICHEAD, 

 Branch of Forest Insects, Bureau of Entomology. 



In one of the series of papers devoted to the fauna of Den- 

 mark, A. C. Jenson-Haarup has discussed the longhorn beetles and 

 K. Henriksen their larvae. 



Henriksen has given a brief and concise discussion of the ana- 

 tomical and biological characteristics of these larvae. Follow- 

 ing this is a table to subfamilies, genera and species. These are 

 constructed with the idea of quickly identifying the species rather 

 than to illustrate any taxonomic relationships. The most con- 

 spicuous characters are used. This has been the first attempt to 

 formulate dichotomous keys for the whole family, which has been 

 avoided by former writers on these larvae. The arrangement 

 of subfamilies essentially follows the excellent work of Schiodte. 

 Original figures illustrate the chief anatomical characters and 

 for nearly every species the dorsal ampullae is figured. In the 

 reviewer's opinion too much stress is laid upon the value of these 

 ampullae. The arrangement of the impressed lines is often in- 

 tensified or obliterated according to the manner in which the 

 larvae have been preserved. The structure of the mandibles 

 and ventral mouth parts is very reliable, and can be used as well 

 for cast skins. 



Fifty-one species are treated. A brief description of each and 

 the food habits are given. A typographical error occurs under 

 Pachyta collaris. It is describee! with two ocelli instead of five, 

 as given in the table. 



A word of comment is necessary on this series of papers de- 

 scribing the Danish fauna. They are more or less popular, pre- 

 pared for the general public but technical enough to accurately 

 identify the species. A large number of volumes prepared 

 by well known experts on each subject have been published, cover- 

 ing birds, mammals, fishes, reptiles, insects, etc. It favorably 

 reflects on a public that can appreciate and demand such 

 publications.
