 r-?» placed a little after fRs; stem of Rs about equal to stem 

 of K2 -4 ;;, the latter about half the length of Rs. 



Hypopygium: Small, side pieces with a very small incon- 

 spicuous internal distal process, which looks like a small spine,

LARV^. 



The three larva^ which have been secured up to now are 

 not referred to the three particular species by way of rearing, 

 but only by simultaneity of capture of the imagines in the 

 same spot whore the larva? had been found. Therefore their 

 identity remains somewhat dubious, although in each case 

 only one species of the adult had been found at the same time 

 with the larva' hereafter described. None of the pupa» 

 are known.
