[Vor,. XIX, 



examine one of them for me, expressed the opinion that it bore a 

 strong resemblance to that genus. This is in fact the case ; the 

 simple posterior margin of the prothorax and the shape of the 

 pterostigma being the most important structural characters which 

 separate it. The specimens are I think certainly very closely 

 related to L, hilineata, Selys, but show some differences in detail. 



Wmgs : Very narrow, hyaline with an uniform brown tinge, 

 and with dark brown venation. Pterostigma bicoloured, its inner 

 three-quarters dark brown, the outer quarter and the distal 

 marginal vein yellowish white. This vein is much less oblique 

 than is the inner marginal vein. The pterostigma is about three 

 times as long as it is broad. 



Ratio of greatest breadth of wing to greatest length about 1:5. 

 Head : Anterior surfaces yellow, dorsal surfaces including the 

 post clypeus bronze-black, margin of occiput finely lined with yellow, 

 posterior surface bronze-black. 



Prothorax : Anterior lobe yellow, middle lobe yellow with a 

 large bronze-black spot on either side, posterior lobe bronze-black, 

 yellowish-white below. 



Synthorax: Pale brownish-yellow, almost white below. On the 

 dorsum is a broad bronze-black band with violet reflex, not 

 separated so far as colour goes from its fellow of the opposite 

 side by the mid-dorsal carina. This band is widened a little at 

 about the middle of its height, and again at its upper end, where 

 it lies against the ante-alar sinus. There are also three small 

 isolated black spots on either side on the mesepimerite. 



Abdomen: Pale brown passing to yellowish-white below. 

 Segment i has a square dorsal patch of bronze-black ; 2 has 



a bilobed band of the same colour, 

 contracted at its middle, and with 

 its hinder lobe bifid. Segments 3-5 

 have each a pair of antero-latera and 

 postero-lateral bronze-black spots, 

 the anterior pair on 5 being very 

 small. 



Segments 6-9 are without definite 

 markings, but the brown colour of 

 the dorsum is definitely darker than 

 in the preceding segments and has a 

 slightly metaUic lustre. Segment 

 10 is yellowish white as are the 

 anal appendages, which are cylin- 

 drical and a little shorter than the 

 last segment. This latter has its 

 posterior margin very shallowly angulate 



Legs : Long, the third femur when adpressed reaching to the 

 base of the first abdominal segment. Colour pale brown, the 

 anterior surface of the tibia, the distal half of the anterior 

 surface of the femur, and the tarsal claws brownish black. Tibial 

 spines exceeding in length the tarsal claws.
