the base and apex ; the lateral angles close to the base ; from them 

 the area becomes gradually narrowed towards the apex, the lateral 

 basal areae large, transversely triangular, the narrowed end on the 

 inner side ; the lateral apical areae are large, narrowed to a sharp 

 point above ; the surface is obscui'ely transversely striated. Trophi 

 testaceous, covered with white hair. Hind tarsi black, the long spur 

 of the hind tibiae two-thirds of the length of the metatarsus.

Black, the face, orbits, greater part of prothorax, scutellum, legs, 

 except the coxae and basal joint of trochanters and hind tarsi, and 

 ventral surface, rufo-testaceous ; maxillae black, the palpi pale testa- 

 ceous ; wings hyaline, iridescent, costa, stigma, and nervures black ;

Head and thorax covered with white pubescence. Head, pro-, 

 and mesothorax smooth, impunctate ; the median segment irregu- 

 larly rugose ; the central area large, reaching from near the l)ase to 

 the apex ; sharply narrowed towards the base and apex ; the widest 

 part is above the middle ; it is the only area.

Black ; the wings yellowish hyaline, smoky at the apex ; the oral region, 

 palpi, and four front legs pale yellow ; the basal 2-4 segments of the abdomen 

 closely striated ; area on second segment small, triangular, smooth or striated. 



This group is somewhat diverse, the main agreement being in 

 coloration ; in form- and structure the species are much more 

 distinct. 



The black species, with yellowish-hyaline wings, infuscated at the 

 apex, known to me, may be separated thus : — 



(/. Abdomen longitudinally striated. 



Ovipositor longer than the body ; the basal five abdominal 

 segments closeh* longitudinally striated ; oral region, man- 

 dibles, and palpi yellowish athiopicus, Cam. 



Ovipositor shorter than the body ; the basal two abdominal 

 segments sparsely striated ; oral region and mandibles 

 black, the apical joint of maxillary imlpi yellow .. .. xanthocarjuiit, Cam.
