REPORT OF THE STATE ENTOMOLOGIST I907 245 



e Sci present and retracted far toward the base of the wing, it being 



anterior to the base of Rs; forks of Rs deep and variable; cord 



at the first fork of M: Pediciinae 



f M deflected posteriorly at its first fork, its base being in line 



with Mi-^2. Cross vein m wanting; base of Rs shorter than 



the distance between the forks of Rs and Cu: (Dicranotae) 



g A supernumerary cross vein in cell Ri Dicranota 



gg No supernumerary cross vein in cell Ri 



h Ml and M2 separate at the tips Rhaphidolabis 



hh Ml and M2 fused to the wing margin Plectromyia 



// The first fork of M more symmetrical, Mi_|_2 being considerably 

 deflected forward at the first fork. Cross vein m usually 

 present: (Pediciae) 

 g Ml and M2 separate to the wing tip 



h With a supernumerary cross vein in the cell Cu, and others 



between the branches of Rs Polyangaeus 



hh No supernumerary cross vein in cell Cu 

 i Basal deflection of Cui meets M after the forking of M 



j Wing tip straight, cord transverse Amalopis 



jj Wing tip decurved; cord very oblique Pedicia 



ii Basal deflection of Cui joins M before the forking 



of M Ornithodes 



gg Ml and M2 fused to the wing margin Ula 



ee Sc2 never retracted toward the wing base so far as the base of 

 Rs; sometimes it is wanting 

 / Cu2 longer than the deflected base of Cui (antennae 13-16 jointed) 

 Limnophilini and Eriopterini 

 g M three branched 



h Cui and Ms fused for a long space, and separating in a 

 symmetrical fork beyond the fusion; cross vein m 



wanting Polymera 



hh Fusion of Cu and Ms moderate, and M3 deflected forward 

 just beyond it; cross vein m usually present 

 i Basal deflection of Cui meets Ms at or before the middle 

 of cell ist M2; 2d A long; Sc forked near its tip 



y A supernumerary cross vein present in cell C , 



Epiphragma 

 jj No supernumerary cross vein in cell C 



k Rs deflected downward at the second fork of Rs 



Cladura 

 kk Second fork of Rs Symmetrical, or R^ deflected up- 

 ward at its base Limnophila 



ii Basal deflection of Cui meets Ms just beyond the middle of 

 cell ist M2; 2d A short and recurved; Sc2 far retracted — 



almost to the base of Rs Trichocera 



gg M two branched 



h Area at front of Rs undergoing reduction ; Rz returned for- 

 ward and shorter than the fused portion of jRz+s 

 } Subcosta short; it.s tip before the base of Rs . . , .Qonomyid.*
