fourth very minute ; fifth and following joints long, linear, slightly- 

 decreasing in length until the tenth ; club linear, conical at the tip, 

 much longer than the tenth joint : thorax nearly oval, very convex ; 

 prothorax rather large, transverse, narrower in front : scutum of the 

 mesothorax large, transverse, having the scales on its surface dis- 

 posed in minute transverse undulations ; sutures of the parapsides 

 distinct, slightly approaching each other ; scutellum truncate-coni- 

 cal, having a very narrow suture at the base : metathorax convex, 

 prominent, decumbent : podeon not more than one- sixth of the 

 length of the abdomen : abdomen nearly conical, smooth, shining, 

 slightly convex, narrower and much shorter than the thorax ; meta- 

 podeon covering more than half the dorsum, slightly concave at the 

 base ; octoon and all the following segments very short : wings ample ; 

 humerus less than half the length of the wing ; ulna scarcely half the 

 length of the humerus ; radius much longer than the ulna ; cubitus 

 about one-half of the length of the ulna ; stigma very large, forming 

 an irregular cone whose tip points toward the radius. 



Found by Dr. Greville near Edinburgh. It is nearly allied to L, 

 elegans.

Female. — Body convex : head and thorax finely squameous : head 

 large, transverse, a little broader than the thorax : antennae short, 

 compact, subclavate, rather shorter than the thorax ; first joint long, 

 linear ; second cyathiform ; third and fourth very minute ; fifth and 

 following joints linear, successively decreasing in length until the 

 tenth, which is as broad as long ; club linear, conical at the tip, 

 much more than twice the length of the tenth joint : thorax very 

 convex : prothorax moderate, transverse ; fore corners rounded : scu- 

 tum of the mesothorax large, longer than broad ,* sutures of the par- 

 apsides very distinct, approaching each other ; axillae large, trian- 

 gular, not conniving ; scutellum truncate-conical, very prominent, 

 not impressed in front, but having a transverse channel before the 

 tip : metathorax large, obconic, decumbent : podeon short, stout, not 

 more than one-sixth of the abdomen in length : abdomen short-oval, 

 shining, very finely squameous, deep, very convex, much shorter and 

 a little narrower than the thorax ; metapodeon conical, quite smooth, 

 channeled and abruptly decumbent towards the fore border, occu- 

 pying a little less than one-third of the dorsum ; octoon more than 

 half the length of the metapodeon ; ennaton shorter than the octoon ; 

 decaton as long as the ennaton ; protelum short ; paratelum and te- 

 lum very short : wings ample ; humerus much less than half the 

 length of the wing ; ulna rather less than half the length of the hu- 

 merus ; radius very much longer than the ulna ; cubitus stout, much 

 shorter than the ulna; stigma large, pyriform, emitting a short 

 branch towards the radius.
