Iphiaulax Ijnceus, sp. nov. 



Black; the wings blackish to the basal ab- 

 scissa of cubitus and the basal posterior part of 

 the 1" cubital cellule, the 2 discoidal cellules and 

 slightly beyond them ; the rest lacteous ; the basal 

 nervures , lower part of 1"' transverse cubital 

 nervure and the base of accessory black ; the 

 Stigma and apical nervures pale ochraceous. 

 Head and thorax smooth and shining; the ab- 

 domen closely longitudinally striated, opaque, the 

 2"'' Segment more strongly striated on eitherside 

 of the keel ; which has the dilated base longer 

 than it is wide and narrowed towards the apex; 

 the ^apical Prolongation is wider than usual and 

 extends to the base of the apical third of the 

 Segment ; it is shining , smooth , except for a 

 few scattered punctures on the base. Suturiform 

 articnlation wide, stoutly striated ; the apex of 

 the 3'''* Segment is depressed and striated; there 

 are distinct, crenulated furrows on the apices of 

 the 4"" and 5'". ?. 



Length 7 mm; terebra 7 mm. 



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



Face rugosely punctured and covered with 

 white pubescence ; there is a smooth line down 

 the centre of the top ; front and vertex weakly 

 punctured; the frontal furrow wide, the centre 

 deep, the sides obliquely sloped. Temples wide, 

 oblique, the occiput slightly rounded. 



Iphiaalax? ingratellus, sp. nov. 

 Black, the head, thorax, fore legs, the middle 

 except the tarsi, underside of antennal scape and 

 tegulae, red ; the ventral surface white, the sides 

 of the Segments with longish black lines , the 

 basal 4 dilated at the base on the innerside, the 

 last Segment with a narrower line all round the 

 onter edges , the 2 lines uniting at the apex, 

 through the segment becoming gradually narrowed 

 to a point ; there is no area on the 2"'' segment; 

 wings dark fuscous , the nervures black , the 

 Stigma dark testaceous; the recurrent nervure 

 is received shortly beyond the transverse basal. 



The hair on the apical half of the sheaths of the 

 ovipositor is white. ?. 



Length 20 mm, terebra 27 mm. 



Sadong , Sarawak , Borneo , August (John 

 Hewitt, B. A.). 



Face sparsely covered with black hair. Tips 

 of mandibles black. There is a distinct keel 

 down the middle of the front, extending from 

 the ocelli to the apex ; its basal half thin , the 

 apical dilated. Abdomen more than double the 

 length of the thorax, the basal 3 segments being 

 longer than it. Metanotum and sternum densely 

 covered with fuscous pubescence. Basal slope of 

 1" abdominal segment smooth, depressed; the 

 following part is oblique, stoutly striated, the 

 Striae clearly separated and with a triangulär, 

 almost smooth , space on the base ; the rest is 

 finely, closely, irregularly striated; the lateral 

 furrow is regularly, somewhat stoutly transversely 

 striated ; at the base and apex of these is , on 

 the outer edge , a tubercle. The 2""^ segment is 

 in the centre of the basal half, regularly longi- 

 tudinally striated, the Striae becoming gradually 

 narrowed to a point; it is bordered by a wide, 

 smooth depressiou, which ends in a fovea ; the 

 rest of the segment is irregularly longitudinally 

 reticulated-striated, the striae more or less broken ; 

 the S"' and 4"^ segments are irregularly reticulated, 

 the Striae more or less broken ; their base 

 longitudinally striated ; there are crenulated 

 furrows on the base of the 3"^, 4"" and ö"* seg- 

 ments ; the lateral spurs are also crenulated ; 

 the space behind than raised, smooth and shining ; 

 the transverse furrov? on the apex of the 5"" is 

 wider and deeper than the others, and the apex 

 is more distinctly curled up. 



This species is an Iphiaulax in all respects, 

 except that the transverse median nervure is not 

 interstitial. There is no genus of Exothccini in 

 which it can be placed. 



Ischuagathis, gen. nov. 

 Discoidal and 1^' cubital cellules not separated. 

 Radial cellule short, narrow; the transverse 

 cubital nervures united in front , the 2'"i with a 

 long branch; transverse median nervure not quite 

 interstitial, being received very shortly beyond 

 the transverse basal. Stigma long , roundly 

 curved behind; the radius issues from shortly 

 behind its centre ; parastigma distinct , longer 

 than wide; the transverse basal nervure is 

 joined to it by a short branch. Eyes large, 

 projecting ; the malar space not quite half their 

 length. Vertex and front without keels. Meso- 

 notum trilobate. Scutellum not margined. Meta- 

 notum not areolated. Abdomen twice the length 

 of the thorax; the 1" segment slender , as long 

 as the following 3 united; these are strongly, 

 closely longitudinally striated. Thorax and 

 apical segments of abdomen densely pilose. Spurs
