tibia adpressed and somewhat weak. Ovipositor sheath nearly two and a half times longer than 

 the hind tibia. Tergite i completely smooth and polished. Tip of ovipositor downcurved and, 

 seen from the side, hardly different from that of grandiculus. 

 Length: 4-5 mm. without ovipositor. 



S. Africa : Cape Province, Ceres, 1,500 ft., 27-x.-xi.1920, 1$, the TYPE, (R. E. 

 Turner). 



Type in the British Museum (Nat. Hist.). 



This is a most distinct species if only on account of the shortness of the median 

 field of tergite (2 + 3). 



The SUNDANUS-Grovf 



At least the femora and trochanters bright reddish yellow ; broad membranous 

 sides of tergite 1 yellow or reddish yellow. 



Head deep from back to front ; the deeply scooped out occipital region extends 

 forwards right up to the ocelli. Distance between the posterior ocellus and the eye- 

 margin distinctly less than twice than longer diameter of the ocellus. 



Metacarp very long, almost closing the radial cell ; 1st abscissa of the radius and 

 the transverse cubitus together forming a very strongly curved vein (Text-fig. 201) ; 

 cubitellan cell of the hind wing distinctly longer than wide ; vannal lobe beyond its 

 widest part with straight edge that sometimes shows a few projecting hairs. Hind 

 coxa very large ; inner spur of the middle tibia reaching to apex of basal segment of 

 tarsus ; legs altogether long and slender. 



Tergite 1 very strongly narrowed behind, its anterior, declivous part deeply hollow- 

 ed out and much paler in colour than the sides and posterior part of the tergite. 

 Ovipositor sheath short, not more than two thirds as long as the hind tibia. 



Indo-oriental region. 



Differs mainly from the menda-growp in having the cubitellan cell of the hind 

 wing longer and longer hind tibial spurs. 



Key to Species 

 Females 



A Hind tibia and hind tarsus dark brown, in sharp contrast with the reddish-yellow hind 

 femur ; hind coxa darkened at base ; posterior half of mesoscutum and the disc of 

 the scutellum dull, with satin-like sheen and only a weak, vague trace of punctation; 

 face impunctate, with pronounced satin-like sheen ; posterior half of gaster almost 

 black ........ sundanus Wilkinson (p. 170) 



B Hind tibia and hind tarsus hardly different in colour from the reddish-yellow hind 

 femur ; hind coxa entirely reddish-yellow ; posterior half of the mesoscutum and 

 the disc of the scutellum shiny, with a satin-like sheen and conspicuously punctate ; 

 face shiny, very distinctly punctate ; posterior half of the gaster reddish brown, 

 becoming reddish-yellow beneath ...... ariadne sp. n. (p. 171)
