* The genera Mesoleptus and Tryphon have been made the receptacle of very 

 discordant material, and most of the .species enumerated in this list under those 

 genera seem more i)roperly to belong to the intermediate genus Me^oleius : but 

 as this cannot be definitely ascertained without a cjireful study and revision of 

 the species, and with more abundant material, they are in most cases permitted 

 to remain in the genera in which they were originally described. The genus 

 Crypfocehtrus Walsh (^ Cryptocentrum Kirby ?), of which Tryphon f submanjinntua 

 Ci'ess., is made the tyjjc, seems scarcely distinct from Mesuleiiui.
