50 Dr. M. Burr — yotes on the Forficulavia. 



Tills striking little black and orange species I first con- 

 fused with L. marginalis ; but, apart from the distribution of 

 Cdlours, the form of the forceps and penultimate ventral 

 segment of the male are distinctive. 



I have pleasure in dedicatino; it to my friend Mr. S. G. 

 Owen, A.R.S.M., who took it in Liberia.
