Very close to L. albofiiy^hriatus, Sich. (Tahiti)j and L. atra- 

 tiformis, Ckll. (Australia), but differing in various small 

 characters. Vertical supraclypeal ridge not reaching lower 

 margin of supraclypeal area, but leaving a punctured region 

 between end of ridge and top of clypeus (no such punctured 

 region in albojimbriatus) ; hair of cheeks and anterior coxse 

 fulvous ; front and occiput with erect black or dark fuscous 

 hair; hair of pleura black ; scutellum not or barely de- 

 pressed in middle ; first recurrent nervure joining second 

 s.m.; marginal nervure of hind wing not bent or angular 

 near origin (in albojimbriatus it is bent or even slightly 

 appeudiculate) ; white abdominal bands as broad as in 

 L. atratiformis ; hair at apex of abdomen entirely black ; 

 sides of abdominal dorsum more strongly punctured than ia 

 albojimbriatus, herein like atratiformis.
