Joppinae. 



Äcanthoj op p a nigrinerva sp. nov. 



Ferrugineous, the 2^* and following segments of the abdomen 

 infuscated , the basal 4 joints of the antennae ferrugineous , the 

 5*^ to 7*^ black, the 8* to 16* white, the rest black ; the legs 

 coloured like the body , the bind tarsi black ; wings hyaline, 

 iridescent , slightly suffused with fulvous , the stigma testaceous, 

 the nervures black. $. Length 11 mm, ovipositor 1 mm. Kuching. 

 Borneo. November. (John Hewitt, B. A.) 



Head smooth, the depressed front finely, closely longitudinally 

 striated in the middle. Mesonotum opaque, granulär, as is also 

 the scutellum which becomes slightly, gradually narrowed towards 

 the apex ; its sides are distinctly raised , its apex incised , the 

 sides of the incision straight, oblique. The basal 3 areae of the 

 metanotum are smooth ; the areola is a little longer than wide, 

 rounded at the base, transverse at the apex, and almost divided 

 into 4 parts by a longitudinal and a transverse keel , the parts 

 between being filled with broken keels or striae ; the other areae 

 are closely, strongly transversely striated. Pleurae closely punc- 

 tured , the meta- more strongly than the mesopleurae ; the pro- 

 pleurae with the apex irregularly striated. The recurrent nervure 

 is received shortly beyond the middle of the areolet ; there is 

 a short stump on the disco-cubital and recurrent nervures. 



The cf is similarly coloured, with the antennae longer and 

 serrate. 



The differences between this species and A. cincticornis Cam. 

 (also found at Kuching) may be shown thus : 



Apex of scutellum transverse, areola wider than long 



cincticornis. 

 Apex of scutellum incised , areola as wide as long 



nigrinerva. 



Ileanta cariniscutis sp. nov. 



Black , a spot on the base and apex of the antennal scape 

 below , the middle of the flagellum broadly , the face, except for 

 a black line on eitherside of the middle, clypeus, labrum, a narrow 

 line on the inner orbits , extending round the top of the eyes, 

 where it becomes narrowed, a large triangulär mark on the outer 

 orbits , commencing shortly above the middle , where it is nar- 

 rowed , mandibles , except at apex , the base of the pronotum
