g-. Abdomen slender, recurved dorsad Camptomyia Kieff. 



/'. Antennal segment not greatly produced in both sexes. 



g^. Basal clasp segment ovate, denticulate apicad; terminal 



clasp segment wanting Dirhlza H. Lw. 



g-. Male genitalia presumably normal; flagellate antennal 

 segments subsessile or nearly so; lobes of the ovipositor 



normal Prodirhiza Kieflf. 



e'. Palpi triarticulate Lopesiella Tav. 



cF. Circumfila of the male forming long loops as in the Itonidinariae. 



e\ Palpi quadriarticulate Lopesia Riibs. 



e". Palpi uniarticulate AUodiplosis Kieff. and Jorg. 



c". Fifth vein simple, the sixth wanting. 



cf. Claws denticulate, as long as the pulvilli or at most twice as 



long as the pulvilli Holoneurus Kieff. 



d". Claws toothed, more than twice the length of the pulvilli. 



Coccopsis Meij. 



LASlOPTERIARI^e 



Key to the genera. 



a\ Third vein very near costa and uniting therewith at or before the basal 

 half, very rarely near the distal third. 

 6\ Mouth parts and thorax normal; that is, not greatly prolonged. 

 r\ Palpi with three or four segments. 



cT. Third and fourth antennal segments coalescent or closely fused; 

 pulvilli always well developed, 

 e'. Three long veins, the fifth forked some distance from its base. 

 /'. Ventral plate bilobed; palpi usually quadriarticulate. 



Lasioptera Meig.* 

 /'. Ventral plate straight, not emarginate; palpi triarticulate. 



Prolasioptera Kieff. 



e-. Four simple long veins Neolasioptera Felt. 



cF. Third and fourth antennal segments not coalescent, at least 

 separated by a distinct constriction; pulvilli sometimes small 

 or rudimentary. 



e\ Palpi quadriarticulate; claws simple Protaplonyx Felt. 



c^. Palpi biarticulate or uniarticulate. 



d\ Third and fourth antennal segments coalescent or closely fused; 



pulvilli always well developed. 



e\ Palpi uni- or biarticulate, rarely triarticulate... Asteromyia Felt. 



dr. Third and fourth antennal segments not coalescent, at least 



separated by a distinct constriction; pulvilli sometimes small or 



rudimentary. 



e\ Palpi biarticulate, claws toothed or simple; terminal lobe of 



the ovipositor rounded, dorsally with a chitinous barbed 



process Stefaniella Kieff. 



* Kieffer has proposed the name Meunieriella for species of Lasioptera 

 without the dorsal group of hooks on the ovipositor. This, if adopted, 

 would mean placing a considerable number of American forms now re- 

 ferred to Lasioptera into this new genus.
