116 THE CANADIAN ENTOMOLOGIST 



reddened above; head black; tibiae with minute spurs; antenna 

 as shown in Fig. 1. 



Wings nearly 6 mm. long, without markings; subcosta branched 

 at end, with lower branch a trifle longer than upper, its termina- 

 tion level with basal end of discal cell; radius straight except for 

 a very slight upward bend at the end; radial sector sharply bent 

 near its origin, with an appendicular nervure directed basad from 

 the angle; R2 and R3 both show a gentle and practically even

curve; upper branch of media forked a considerable distance be- 

 yond end of discal cell, the stem a little longer than the fork; 

 radial cross-vein joining radial sector at base of fork of its upper 

 division (as in L. nacrea and lentoides figured by Alexander, and 

 L. rogersii figured by Scudder) ; posterior cross-vein joining discal 

 cell a little beyond middle; Cu2 sharply deflected downward at its 

 end. 



The following measurements are in microns: end of Sc2 to 

 radial cross-vein, 784; upper apical corner- of first basal cell to 

 separation of R2 from Rs, 496; radial sector from basal angle to 

 end of first basal cell, 1089; discal cell on second basal, 352; discal 

 cell a fifth posterior, 240; first posterior on third, 640; first posterior 

 on second, 592. 



In Baltic Amber; received fi^m Mr. F. H. Ward. 



This appears to be distinct from all the species described by 

 Meunier from amber. The antennae have bristles resembling those 

 of L. vulcana, but the basal joint is far more robust. The wings 

 appear to be quite distinctive.
