TAXONOMIC NOTES ON AGATHINAE (HYMENOPTERA- 

 BRACONID.E).

A New Definition of Crassomicrodus Ashmead. 

 A study of the type of Microdus fulvescens Cresson, designated 

 by Ashmead as type of his genus Crassomicrodus (Proc. U. S. Nat. 

 Mus., vol. 23, p. 128, 1900), reveals the fact that in this species the 

 hind wings have no closed discoidal cell and the longer spurs of 

 the posterior tibise are decidedly less than one half of the length 

 of the metatarsi. These are the characters upon which Ashmead 

 based his genus and by which he separated it from Epimicrodus. 

 The designated type of the latter genus is Microdus diversus Cres- 

 son, undoubtedly, as Mr. Viereck has already pointed out, a mis- 

 print for divisus Cresson, since Mr. Cresson never described a 

 Microdus under the name diversus. Moreover divisus agrees well 

 with most of the characters assigned by Ashmead to the genus 

 Epimicrodus.
