Nymph. 



Brauer describes the n}^mph of L. iiyinpJia ( --=■- diyas) 

 as follows : " Maske sehr lang, schmal, bis zwischen die 

 Hinterbeine reichend ; die funf vorletzten Hinterleibs 

 segmente zeigen einen kurzen, geraden seitenstachel ; 

 kiemen lang, breit " (Brauer and Low, " Neuroptera 

 Austriaca," p. xvi., 1857). Translation : " Mask very 

 long, slender, reaching as far as between the hind- 

 legs ; the last five segments but one of the abdomen 

 have a short, straight, lateral spine ; lamella; long and 

 broad." [This description is generic rather than specific ; 

 it will apply equally well to L. spotisai\
