REPORT OF THE STATE ENTOMOLOGIST I907 ^47 



// Posterior end of the cord pushed outward toward the wing 

 margin, making the basal deflected part of Cui longer than Cu2 



Anisomerini 

 g Sc2 longer than Sci; second fork of M unsymmetrical, Mi at 



base being deflected forward : . .Penthoptera 



gg Scx 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 



hh Median vein reduced to a single branch; R2 shorter than 



the fused part of Rij^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 /?2+3 



g Cell ist M2 or equivalent space widened distally; tip of i?2-|-3 

 curved forward 

 h Tips of veins i?4-|-5 and Mi_[_2 arcuated and parallel, but not 



approximated Teucholabis 



hh Tips of veins R^j^^ and Mi-|_2 distinctly approximated 



Dicranomyia in part \.see pi. 17, fig. 4] 

 gg Tip of i^o+s straight; cell ist M2 open 

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



absent Orimarga 



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

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

 // Fork of Rs symmetrical, or nearly so 

 g Cross vein r wanting; Ri quite separate from RiJ^z 



h i?2-|-3 straight and strongly divergent from Ri-\^^; cross vein 



r-m reduced by fusion of adjacent veins Rhamphidia 



hh i?2-(-3 usually arched more or less ; not strongly divergent 

 from i?4_|-5 

 i Basal angulation of vein Mij^2 where it touches the cross 

 vein r-ni, acute ; Sc2 at tip of Sc; basal angulation of 



Cux at the middle of cell ist M2 Elephantomyia 



ii Basal angulation of vein lfi-|_2 where it touches cross vein 

 r-m, 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 R\ 

 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 Cu2 Dicranoptycha 



ii Furrow not so situated, but closer to Cu
