from the rest than it is in Santabongensis, in which the sculpture 

 of the segment is more uniform ; in the latter the 2 nd abdominal 

 segment is wider at the apex than it is long, while in megaspilus 

 it is longer than it is wide at the apex ; there is a difference, 

 too, in the form of the post-scutellum ; in the present species its 

 apex is bluntly rounded ; in megaspilus , it becomes gradually 

 obliquely narrowed to a blunt point , its pleural markings , also, 

 are larger, the upper being broader, especially below, where it is 

 broadly rounded ; the base of the thorax , too , is not so trans- 

 verse, the sides being more broadly rounded. 



Icaria erythrospila sp. nov. 



Black, a broad line on the base of the clypeus, on the sides 

 and extending to shortly beyond the middle ; it being slightly, 

 gradually narrowed towards the apex , a short line at the eyes 

 opposite to and below the antennae , and a spot on the base of 

 the mandibles, pale yellow, the prothorax and a large spot, longer 

 than wide, rounded at the base, in the centre of the mesonotum 

 at the apex rufous ; the scutellums yellow tinged with rufous, 

 the scutellum with a more rufous tinge than the post-scutellum ; 

 there is a small rufo-yellow spot on eitherside of the metanotum 

 near the apex ; there is a narrow , but distinct obscure yellow 

 line , with an irregulär basal edge at the base on the apex of 

 the 2 nd abdominal segment all round , there is a small yellow 

 spot on the apex of the l st on the sides , and a smaller one in 

 the centre of the apex. Tibiae yellow, the hinder broadly, irre- 

 gularly black at the apex. Underside of antennal scape yellow. 

 Wings hyaline , the radial cellule , except at the base behind, 

 blackish. $. — Length to end of 2 nd abdominal segment 6 — 7 mm. 



Kuching. September. (John H e w i 1 1.) 



Head and thorax covered with short , white pubescence, 

 closely, but not strongly punctured, the clypeus is shining, almost 

 smooth. Post-scutellum with distinct, clearly separated punctures 

 at the base and sides , the punctured part wider on the sides 

 than at the centre of the base ; the rest smooth and shining. 

 Sides of metanotum above with some irregularly oblique Striae, 

 the sides below more finely , transversely striated ; the centre 

 deeply , widely excavated , smooth , shining. Abdominal petiole 

 distinetly narrowed at the base , the apex cup-shaped , narrowed 

 roundly at the base , as long as it is wide at the apex ; the 

 2 nd segment is longer than it is wide at the apex. 



Comes nearest to /. malayana Cam. ; in that species the 

 lower half of the prothorax is black , the sides of the clypeus
