218 ON LEUCOSPIS. 



I think it not improbable, that the insect described by Mr. 

 Walker as a doubtful variety of the male of L. dorsigera 

 {Enf. Mag. Vol. II. p. 20) is the male of the above described 

 species, regard being had to the circumstance, that in the 

 species allied to L. dorsigera the females are distinguished by 

 a greater share of yellow colour than the opposite sex.
