British Species of Allotrince. 63 



club distinct ; the joints moderately elongate ; the last 

 sharply conical at the apex and longer than the others. 

 Scutellum laterally opaque, closely, longitudinally striolate ; 

 the foveae deep, wide, distinctly separated ; the apical fovea 

 small, shallow, circular ; at the apex the scutellum broadly 

 projects, narrowing towards the bottom, but not forming a 

 beak as in the section Rhyncacis ; abdomen longer than the 

 head and thorax united ; the hair fringe dense, large, grise- 

 ous. Radial cellule an elongate triangle, closed at base and 

 apex ; the nervures straight, the second abscissa fully one- 

 fourth shorter than the third ; cubitus traced ; apex of wing 

 roundly incised. 9 



Length slightly over 2 mm. 



In general coloration this species comes nearest to K. 

 Jilicornis, but differs from it in its much greater size ; in the 

 projecting apex of the scutellum (forming a transition to 

 Rhyjicacis) in the longer abdomen and in the clearly indi- 

 cated cubitus.

Kleditoma gracilicornis, sp. nov. 



Black ; the knees and tarsi piceous ; wings clear hyaline, 

 the nervures piceous. Antennae thin, twice the length of 

 the thorax ; the third joint one-half longer than the fourth, 

 the 4—8 wider than long ; the ninth oblong, thicker and 

 nearly twice longer than the eighth, and three-fourths of 

 the width of the tenth ; the 4-jointed club not very abrupt, 

 the three basal joints of nearly equal thickness and length, 

 oval ; the last longer and sharply conical at the apex. 

 Radial cellule subtriangular ; the second and third abscissa; 

 of the radius subequal. Scutellum aciculate ; the basal 

 foveae longer than wide. Abdomen longer than the thorax 

 and head united ; the hair fringe moderate, whitish. Apical 

 incision in wings slight. ?. 



Length i mm.
