forked, with tbe branches little more than half tlie length of the petiole.

 finely pubescent; knees and tarsi dusky." 



The veining of the wings very nearly agrees with L. nemoralis : 

 the fork of the radial vein and of the first exteriio-medial vein is 

 shorter ; the subcostal and the mediastinal are evidently con- 

 nected ; the radial transverse veinlct is nearer the origin of the 

 anterior radial branch ; the veins are more strongly and exten- 

 sively pubescent than in that species, and the membrane also is 

 pubescent towards the tip. L. nemoralis has sixteen-jointed an- 

 tennae, and therefore cannot be referred to the same genus. From 

 B. bimacidata, besides the perfect discal areolet, it differs in the 

 wings, by the radial vein originating further from the end of the 

 wing, the anterior branch joined to the subcostal by only one 

 veinlet, and the pubescent veins." — Hal'ulaij, JISS.
