stigma black ; the costa and base of stigma dark ferruginous. Head 

 and thorax closely, distinctly, but not very strongly punctured and 

 covered closely with a short pale pile. Scutellum more closely, 

 rugosely punctured than the mesonotum. Base of metanotum 

 depressed ; the keels commence at the apex of the depression ; 

 there is a keel down the centre, from its base one runs round 

 the edges ; there is an area on the outer edge in the middle, 

 straight on the outer side, roundly narrowed on the inner. The 

 basal abscissa of the cubitus is as long as the recurrent nervure. 

 Abdominal petiole dilated beyond the stigma. The eyes are very 

 black and shining. Abdomen strongly compressed, broader than 

 usual viewed from the sides, sabre-shaped ; it becomes gradually 

 wider from the base of the second segment. The antennae are 

 shorter and thicker than usual (shorter than the abdomen) ; they 

 taper towards the apex. $ .

To the description of this genus (Records Albany Museum, i., 147), 

 should be added : Apex of clypeus triangularly incised. I have two

Head and thorax rufous marked with yellow, legs with 



coxae rufous /lavomaculatiis, Cam. 



Head and thorax black, marked with yellow; legs 



rufous, the coxae and trochanters black, marked with 



yellow. 



Face, centre of mesonotum, and pleurae immaculate., rujidens. 



Face, centre of mesonotum, and pleurae maculate . . hidentatus. 



Ophioneuea eufidens, sp. nov. 



Black; the abdomen, except the first segment, ferruginous, a 

 line on the inner orbits, a broader one on the outer, two triangular 

 spots on the sides of the mesonotum at the base ; the scutellums, 

 a large mark on the apical half of the metanotum, tripartate at the 

 base, the projections narrowed to a point, the central being the 

 longer and sharper, yellow. Legs ferruginous, the four anterior 

 coxae and trochanters for the greater part yellow, the hinder black, 

 the coxae with a large mark above ; the hind tarsi black. ^ .
