REPORT OF THE STATE ENTOMOLOGIST I907 247 



ff Posterior end of the cord pushed outward toward the wing 

 margin, making the basal deflected part of Cmi longer than Cui 



Anisonierini 

 g Sc-. longer than Sci ; second fork of 11 unsymmetrical, Mi at 



base being deflected forward Penthoptera 



gg Sci longer than Sc-; second fork of the median vein when 

 present nearly or quite symmetrical 

 h Median vein two to three branched; R2 longer than the fused 



part of i?i^2 Eriocera 



Jih Median vein reduced to a single branch; R-. shorter than 



the fused part of i?,^2 Anisomera 



dd Rs two branched Limnobiini and Antochini 



e Sc present; Rs arcuated at its origin 

 / Fork of Rs skewed downward, its base in line with R2-\.3 

 g Cell 1st il/2 or equivalent space widened distally; tip of i?2-|-3 

 curved forward 

 h Tips of veins Rij^^ and Mi^^ arcuated and parallel, but not 



approximated Teucholabis 



Ml Tips of veins Rtj^-^ and il/i_|_2 distinctly approximated 



Dicranomyia in part Vsee pi. 17, fig. 4] 

 gg Tip of 7?2-)-3 straight; cell ist il/2 open 

 h Cell M much shorter than cell R; cross vein in 



absent Orimarga 



hh Cell M as long as cell R; base of Ma atrophied, leaving 

 that vein supported in the reflexed cross vein m. .EUiptera 

 // Fork of Rs symmetrical, or nearly so 

 g Cross vein r wanting; Rx quite separate from 7?2-f3 



h 7?2+3 straight and strongly divergent from i?4+5; cross vein 



r-m reduced by fusion of adjacent veins Rhamphidia 



hh 7?2+3 usually arched more or less; not strongly divergent 

 from i?4-f-5 

 i Basal angulation of vein il/,_^2 where it touches the cross 

 vein r-m, acute; Sc- at tip of Sc; basal angulation of 



Cui at the middle of cell ist AU Elephantomyia 



a Basal angulation of vein Mi-^2 where it touches cross vein 

 r-)ii, very obtuse; Sc2 considerably before the apex of 

 Sci] Cui joins the median vein at or near its 



fork Atarba 



gg Cross vein r present, sometimes attached upon the tip of Ri 

 h A supernumerary cross vein present between the two anal 



veins in their middle portion Discobola 



hh No such supernumerary cross vein 



i A well marked furrow springing from the middle of ist A 



extends toward the tip of C"»2 Dicranoptycha 



a Furrow not so situated, but closer to Cu
