.sparser on centres of ventral segments. Front tibiae widened and 

 furnished on their outer edges with a few very blunt teeth, directed 

 forwards; the intermediate and hind tibiae have on their outer 

 edges some minute spinous processes; femora and tibiae fairly strongly 

 punctured. 



Length, 25 mm. 



2 Differs from the cT in the following characters: — Prothorax 

 a little broader, with sides showing a tendency towards angulation 

 just behind the middle, and pubescence mostly confined to the sides 

 and front margin, leaving the disc almost glabrous; antennae much 

 shorter, barely reaching the middle of elytra, and much more slender, 

 though the scape differs in being broader than the third joint; the 

 puncturation of joints 3-7 inclusive is much coarser than in the c?' 

 and the nitid spaces at the apices of the joints are much more 

 extensive and traceable to the 9th joint. The mandibles do not 

 exhibit any sexual dimorphism. The front tibiae are armed with 

 six rather sharp teeth, and the spiny processes on the other tibiae 

 are rather more apparent; the tarsi are a little less widened than 

 in the S" , 



Length (excluding ovipositor), 28.5 mm. 



It is with some hesitation that I have placed this species under 

 Pascoe's genus Elaptus, firstly, because of the armature of the front 

 tibiae, (Pascoe says "tibiae baud dentatae,") and secondly because the 

 prothorax differs in shape so much from all the other members of 

 the genus. 



There is a small <^ before me measuring only 19 mm. in length 

 in which the antennae almost attain the full length of the insect.

Cnemoplites (Hermerius) intermedia, n.sp. 



^, Dark chestnut-brown, prothorax a little darker; head and 

 prothorax sparsely clothed with short upright pale pubescence, this 

 lacking on the smooth, glossy discal areas of prothorax; anterior 

 tibiae strongly hirsute beneath on their outer halves, this character 

 becoming less pronounced on the four hind tibiae; shoulders, slightly 

 pubescent; undersurface of head and prothorax with clothing similar 

 to that upon their dorsal surfaces; metasternum and its episternums 

 densely clothed with a very much shorter, and somewhat decumbent 

 golden pubescence, this almost wanting on disc, but possibly due to 

 abrasion; the brushes of the ventral segments are very dense and 

 golden in colour, and semi-lunar in shape on the first four arches; 

 on the last segment the hairs are shorter, and occupy a fairly large 

 zone around the vent.
