3. KLEDITOMA CEASSIOLAVA. 

 PI. XIII, fig. 8. 



Kleditoma crassiclava, Cam., Mem. Lit. and Phil. Soc. Man., 

 i (4), 166. 



Black, shining ; the knees and tarsi piceous ; wings yellowish- 

 hyaline, the nervures piceous; abdominal hair-fringe whitish. An- 

 tennae nearly as long as the head and thorax united ; the club stout, 

 thick ; its basal joint distinctly shorter and narrower than the twelfth. 

 Apical margin of wing obtusely rounded, but very slightly incised. 

 Apex of scutellum prolonged into a beak. 



Length 2 mm. 



May be known from nigra by being longer and 

 stouter, by the stouter antennal club, by the blacker 

 legs, and by the apical margin of the wings being hardly 

 excised. 



Rare. Bonar Bridge, Sutherlandshire. 



B. Scutellum not produced behind into a curved beak, 

 rounded at apex, not broadly projecting, and re- 

 treating from the apex to the base. 



i. Antennae with a three-jointed club (= Kleditoma).
