Synopsis of Sphecodinae. 



By Charles Robkrtson, Carlinville, Illinois. 



This paper belongs with one on Andreninae, in Trans. Am. 

 Ent. Soc, xxviii, 187-194, June, 1902, and another on Halic- 

 tinse, in Can. Ent., xxxiv, 245-250, Sept., 1902, intended to 

 put the results of my studies of the local bees in a more con- 

 venient and definite form. 



The species of this group fall into several generic divisions. 

 In the group of larger species, in which the male has the fourth 

 joint of the antennae long, the majority agree fairly well in 

 structure with Sphecodes gibbus, which I regard as the type, 

 and are referred to the same genus. S . falcifer V\X\i. is made 

 the type of the new genus Drepanium on account of the simple 

 mandibles of the female. ^S. ranunculi Rob. is proposed as the 

 type of the new genus Proteraner. The male has the abdomen 

 broadly rounded at apex and entirely red, except sometimes 

 at the base. It differs from all of the other species, and from 

 all of the Halictinse, from the fact that the male appears in 

 spring with the female. 



In the second group, in which the male has the fourth joint
