Subtribe C. f Anisodactyli.) 

 This group comprises the single genus: 



LXXIII. Anisodactylus De.j., 1829. (Gr., "unequal-toed.") 



A large genus of medium sized black, brownish or piceous beetles 

 having the dilated joints of the tarsi of male spongy pubescent in- 

 stead of scaly beneath. They occur in various situations, the ma- 

 jority being found in dry, upland, open woods, beneath logs and 

 other cover. A number of our species hibernate and some of them 

 are very common at electric light. Of 31 specimens dissected by 

 Dr. Forbes, 21 per cent, of the stomach content was found to be of 

 animal, and 79 per cent, of vegetable origin, mainly seeds, pollen of 

 gra.sses, etc., so that it is very doubtful if this genus can be classed 

 among the beneficial Carabidse. The papers treating of the genus 

 are as follows:
