forked, with the branches little more than half the 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 externo-medial vein is 

 shorter; the subcostal and the mediastinal are evidently con- 

 nected ; the radial transverse veinlet 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 

 D. bimaculata, 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." Haliday, MSS.

Body small, elongated, narrow, pilose. Head small, subclavate. 

 Front broad. Eyes round, remote. Proboscis rather long. Palpi 

 four-jointed, incumbent, rather long; fourth joint rather longer than 

 each of the others. Antennne seventeen-jointed, porrect, simple, sub-

 of the length of the wing ; subcostal ending at about five-sixths of the

 radial and petiole springing from a common petiole, which they rather 

 exceed in length, and which proceeds from the subcostal at a little be-
