1. KLEDITOMA NIGRIPES. 

 PI. XIII, fig. 6. 



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

 i (4), 165. 



Black; knees and base of tarsi piceous; wings hyaline, nervures 

 piceous-black. Antennae longer than the head and thorax united ; the 

 third joint attenuate at the base, twice the length of the fourth ; the 

 fourth and fifth joints narrowed at the base, longer than broad ; joints 

 6 10 moniliform, as broad as long ; joint 11 distinctly thicker than 

 the tenth, but shorter and thinner than the eleventh, which is about 

 one-fourth shorter than the thirteenth, the three forming a well-marked 

 club. Occiput striated. Sides of scutellum longitudinally striated ; 

 the discal fovea small, shallow, indistinct ; apex of scutellum below 

 the cup forming a curved, hook-shaped projection. Median segment 

 aciculate, depressed at the base. Abdomen scarcely so long as the head 

 and thorax united; the hair-fringe thick, large, griseous. Radial 

 cellule open at base and apex; the second abscissa of radius three- 

 fourths of the length of third. 



Length 2'3 mm. 



This is the largest species of Kleditoma belonging to 

 this section. It is most nearly related to K. nigra, but 

 the much darker legs and wing nervures, the striated 

 occiput, the more elongated radial cellule, which is dis- 

 tinctly open at base and apex, and the sharper beak- 

 shaped apex of scutellum, sufficiently distinguish it 

 from the smaller nigra. 



Rare. Dulwich (T. R,. Billups).
