/". Claws not strongly curved and therefore not forming almost 

 a right angle. 

 g^. Ventral plate almost linear, straight and much longer than 



the dorsal plate Acaroletes Kieff. 



g-. Ventral plate not greatly produced; lobes of the dorsal 

 plate not divided, cleft or triangularly emarginate; 

 female flagellate antennal segments with normal, low 



circumfila; ovipositor short Mycodiplosis Riibs. 



g^. The female differs from Mycodiplosis in the two circumfila 

 being produced as distinct and very short bows. Male 



unknown Camptodiplosis Kieff.* 



fc^ Palpi triarticulate.f 



c\ Claws not bent at nearly right angles; three well-developed cir- 

 cumfila. 

 tf . Terminal clasp segment not greatly produced; ventral plate short 



and broad Diadiplosis Felt. 



cf. Terminal clasp segment greatly produced, with a length twice 



that of the basal clasp segment; ventral plate longer than the 



dorsal, moderately broad, rounded apically.... Xipliodiplosis Felt. 



c'. Claws bent at nearly right angles; two well-developed and one 



rudimentary circumfilum ; ventral plate linear, roundly emarginate 



apically Chelobremia Kieff. 



a^ Claws simple or not toothed on any of the legs. 

 b\ Palpi quadriarticulate. 



c\ The third vein uniting with the margin before the apex of the wing. 

 (P. Wings hyaline. 



e^. Pulvilli as long or nearly as long as the claws. 

 p. Stems of the flagellate antennal segments mostly with a length 

 less than the diameter; circumfila rather short; ventral 

 plate deeply bilobed, not greatly produced. 



Arthrocnodax Riibs. (Feltodiplosis Kieff.). 



/". Stems of the flagellate antennal segments probably rather 



long; circumfila moderately long; ventral plate much 



longer than dorsal plate, slender, greatly enlarged apicad, 



the distal portion with a width twice its breadth and 



slightly emarginate apicad Microdiplosis Tav. 



e\ Pulvilli one-half the length of the claws or less. 

 p. Terminal clasp segment swollen and long-haired basally, 

 distally slender and smooth; ovipositor not produced. 



Silvestrina Kieff. 

 f: Male unknown; female with the pulvilli hardly one-third the 



length of the sickle-shaped claws Planodiplosis Kieff.J 



d*. Wings densely brown-haired, with clearer spots; costa with black 

 scales as in Lasioptera. 

 e\ Antennal hairs finely denticulate; thorax densely covered with 

 yellow scales Chrysodiplosis Kieff. 



* This genus, Baeodiplosis Kieff., and Alethediplosis Tav. are known 

 only in the female and presumably fall here in the tabulation. 

 ■f Epihermomyia Felt (see p. 315) may fall here in the key. 

 t Location provisional.
