The bibliography given above for the genus is not complete, as only 

 the more important articles are cited, and especially those dealing with 

 the American species. In the above papers by Melsheimer (1853), 

 Lacordaire (1857), LeConte (1863), Gemminger and Harold (1869), 

 Saunders ( 1871 ), Crotch (1873), Austin (1880), Henshaw (1885,1895), 

 Kerremans (1892, 1903), Leng (1920), Leng and Mutchler (1927,1933), 

 and Blackw T elder (1939) many American species of Chrysobothris are 

 listed, but since these publications are only catalogues, the citations are 

 omitted from the bibliography under the species. 



The larvae of Chrysobothris attack both deciduous and coniferous 

 trees, as well as shrubs and herbaceous plants. Some species attack only 

 conifers, some only deciduous trees, while others attack both. Plants 

 of all ages may be attacked, and any part of the plant from the roots to 

 the twigs, but the parts most subject to attack are the bark and wood of 

 the main trunk, the larvae causing worm holes and making lumber from 

 infested trees unfit for high-grade uses. 



DESCRIPTION OF THE GENUS 



Head vertical, the front even or uneven, much wider at bottom than at vertex, 

 and narrowed by the insertion of the antennae ; clypeus broad, more or less sinuate 

 or emarginate in front, and constricted posteriorly by the antennal cavities, which 

 are small and rounded. Antenna variable in shape, sometimes bipectinate in the
