Descriptions of Neu' Species 0/ Parasitic Hymcnoptera. 51 



centre raised, broad, not forming an area or a keel ; the raised sides 

 forming a smooth, elongated triangle, the broad end on the outer 

 side ; sutm'iform articulation wide, deep, the apical bi-anch almost 

 smooth ; there are wide smooth furrows, separated in the centre, on 

 the apices of the third and fourth segments ; that on the third with 

 a few scattered keels. Eecurrent nervure interstitial ; the third 

 abscissa of the radius longer than the basal two united. 



This seems to be a good species. It is distinctly smaller than the 

 others, has paler wings, and the median segment is entirely black, 

 the meso- and propleuraa being also more largely black. 



Iphiaulax dodsi, sp. nov. 



Vermilion-red ; the oral region and mandibles pale yellow ; the 

 palpi yellowish testaceous ; the antennae, tips of mandibles, the 

 middle of front, vertex, and occiput broadly black ; the mark slightly 

 narrowed below ; a broad black line on the sides of the presternum . 

 Antennae black, longer than the body ; the scape twice longer than 

 wide. Wings uniformly dark fuscous, the costa and stigma coloured 

 like the body. ? . 



Length 10 mm. ; terebra 4 mm. 



Southern Ehodesia. Sebakwe. 



Palpi pale rufous, paler towards the apex and covered with white 

 pubescence. Eaised central part of first abdominal segment strongly 

 sharply striated ; the lateral furrow with three stout transverse keels 

 at the base ; the second segment strongly, sharply striated ; the 

 lateral basal furrows deep ; the lateral area large, triangular, smooth, 

 pilose ; the third segment closely, longitudinally rugosely punctured, 

 the fourth similarly, but not so strongly punctured ; the fifth irre- 

 gularly, not very strongly punctured in the centre ; its sides and the 

 other segments smooth ; the first furrow is deep, wide, strongly 

 striated ; the second narrower, not so strongly striated ; there is a 

 narrow, deep, not very closely crenulated furrow on the apex of the 

 third, fourth, and fifth segments ; these are tinged with yellow ; 

 there is no raised area on the base of the second segment. 



Eesembles I. varipalpis ; that species has the third and fourth 

 abdominal segments impunctate. 



■'■ Iphiaulax lativentris, sp. nov. 

 Eufous, a large mark on the centre of the vertex and front, nar- 

 rowed below, one slightly narrower on the centre of the occiput and
