EXPLANATION OF PLATE IV. 

 A phylogenetic tree of the dragonflies of the genus Libelhila, based on 



penes. 



All figures are by camera lucida to the same scale. Because of the 

 limits of the plate, species have had to be shown in series that should be 

 on short lateral branches.

A Change of Name in the Saldidae (Hemiptera) 



1 have recently described a species of Saldidae as Sahhila emnata 

 (Proc. Ent. Soc. British Columbia, No. 18, Syst. Sen, p. 21, 1^21), but, 

 as I am reminded by Dr. E. !'.< r.urnth, this name is preoccupied by 

 Salda cantata Champion (Biol. Centr.-Amer., Ins., Khyiu-b. II., p. ,!41. 

 1900). The two are undoubtedly congeneric and hence I would propose 

 Saldnla eontalnla. nom. nov., for my species. H. M. I ' \KSHI.KV, Smith
