 SERPHID^. (HYMENOPTERA.) 1

The family Serphidse, long familiar to entomologists as the Proc- 

 totrypidae, includes a considerable number of very closely related 

 species from many parts of the world. The group is well repre- 

 sented in the Xearctic region from whence numerous species have 

 already been described. In going over material which has accumu- 

 lated during a number of years, I have found a few undescribed 

 forms which are described in the present paper. 



The first Xorth American species were early described by Say ; a 

 couple were added much later by Provancher, but the family received 

 no serious attention at the hands of American entomologists till 1893 

 when Ashmead 2 published descriptions of all the known Xorth 

 American species. He included twenty-one species, all under the 

 name Proctotrupes and considered the group as a subfamily. Since 

 that time a number of species have been added, including some spe- 

 cies of the genus Disogmus hitherto known only from Europe. Quite 

 recently Kieffer 3 has subdivided the old Proctotrypcs into four
