Microdus fulvescens Cresson agrees generically in all respects 

 with Microdvs divisvs Cresson, of which I have also examined the 

 type. It is, therefore, necessary to unite the two genera. Cras- 

 somicrodus has page priority and will, therefore, take precedence 

 over Epimicrodus. 



Spilomicrodus Cameron possesses the characters erroneously 

 assigned to Crassomicrodus by Dr. Ashmead in his key {loc. cit.) 

 and should, therefore, replace the latter name in that key, while 

 Crassomicrodus should there replace Epimicrodus. 



Crassomicrodus Ashmead. 



1900. Crassomicrodus Ashmead. Proc. U. S. Nat. Mus. 32:128. 



(Type: Microdus fulvescens Cresson.) 

 1900. Epimicrodus Ashmead. Proc. U. S. Nat. Mus. 32:129. 



(Type: Microdus diversus [sic] = divisus Cresson.) 



Malar space short, or only slightly lengthened, not rostriform 

 as in Agathis ; maxillary palpi slender, five-segmented, the second 

 segment slender; parapsidal furrows distinct; mesopleural fur- 

 row strong, foveolate; propodeum not areolated, its spiracles 

 small and round. First and second discoidal cells separate; sec- 

 ond cubital cell petiolate, small and triangular; hind wings with- 

 out a closed discoidal cell. Longer hind tibial spur less than one 

 half the length of the metatarsus; claws large, simple; ovipositor 

 not exserted. 



The Generic Position of Two Cuban Agathin.s:. 



Microdus fasciipennis Cresson, of which I have examined the 

 type belongs to Zelomorphidea \ iereck, a subgenus of Zelomor- 

 phus. Mr. Viereck has ventured the suggestion that all the South 

 American Disophrys probably belong to Zelomorphidea, and in 

 the main I suspect that he is correct. Nevertheless Agathis cub- 

 ensis Cresson, of which I have also studied the type, is more closely 

 allied with Disophrys than with any other described genus, and 

 should be placed in that genus pending an opportunity for a criti- 

 cal revision of the genera of Agathinse. Its claws are cleft, its 

 areola quadrate, its face elongate, rostriform, and its hind legs 

 stout.
