224 KLEDITOMA AFF1NIS. 



11. KLEDITOMA TETRATOMA. 

 PI. XIII, fig. 4. 



Kleditoma tetratoma, Thorns., Oef., 1867, 399, 8. 



Black, shining ; the knees, tibiae, and tarsi piceous ; wings hyaline, 

 the nervures piceous ; abdominal hair-fringe large, griseous. Antennae 

 longer than the head and thorax united ; the club abrupt ; the third 

 joint more than twice the length of the fourth ; joints four to seven 

 dilated towards the apex, which is truncated ; joints eight and nine 

 more moniliform, the ninth a little longer and thicker than the eighth, 

 and fully half the length of the tenth ; joints ten to thirteen becoming 

 gradually longer towards the apex. Scutellum longitudinally striolated 

 laterally, the cup minute, its margin piceous. Abdomen with a distinct 

 petiole, as long as the head and thorax united. Radial cellule small, 

 the second abscissa longer than first. 



Length nearly 2 mm. 



Not common. Clydesdale. 

 Continental distribution : Sweden. 



12. KLEDITOMA AFFINIS. 



Kleditoma affinis, Cam., Mem. Lit. and Phil. Soc. Man., ii (4), 64. 



Black, shining; the trochanters, knees, and tarsi piceous; wings 

 hyaline, the nervures dark piceous. Antennae longer than the head 

 and thorax united ; the third joint not one-half longer than the 

 fourth ; joints four to eight dilated towards the apex, longer than broad ; 

 the apices truncated; the ninth distinctly broader than the eighth, and 

 a little longer than it ; the club abrupt, distinctly separated ; the joints 

 of nearly equal thickness and becoming gradually longer towards the 

 apex ; the tenth a little narrower than the eleventh. Radial cellule rather 

 elongate, closed at base and apex ; the second abscissa of radius dis- 

 tinctly longer than the first. Prothorax and median segment slightly 

 pilose ; abdominal hair-fringe dense, griseous ; abdomen as long as the 

 head and thorax united, scarcely petiolated. Scutellum laterally finely 

 striolated. 



Length If mm. 



Very similar to K. tetratoma, Thorns., but may be 

 easily known from it by the third antennal joint not 

 being twice the length of the fourth, and by the shorter 

 abdomen. 



Bonar Bridge, Sutherland shire.
