furrow near the base of the 4th. Legs densely pilose. Fore tarsi 

 about twice the length of the tibiee, the basal 2 joints together 

 as long as them. Sheaths of ovipositor broad, densely pilose. 

 The sides aud ventral surface of 1st. abdominal segment white. 



Ipliiaulax trichiothecus, sp. nov. 



Black, the head, thorax, frontiers and more or less of the 

 middle legs at the base, red ; wings dark fuscous, the nervures 

 and stigma black ; the back of the abdomen suffused with brown ; 

 tips of sheaths of ovipositor broadly white ; they are broad and 

 densely pilose : "2nd. 3rd. and 4th. abdominal segments closely, 

 strongly, longitudinally striated ; the area on 2nd segment fully 

 twice longer than its width at the base ; it becomes gradually 

 narrowed to a fine point : its base rounded, smooth, irregularly, 

 closely longitudinally striated ; there is a smooth plate, broad at 

 the base, narrowed towards the apex on either side of it ; its keel 

 is narrow, irregular and reaches to the apex of the segment ; the 

 space on either side of it is irregularly reticulated ; the sides 

 depressed, closely obliquely striated : suturiform articulation 

 deep, crenulated ; the furrow on the 3rd. segment is more irreg- 

 ular and is irregularly striated ; there is a smooth, curved fur- 

 row on the base of the 4th. segment. 9 . 



Length 9 mm. : terebra 16 mm.

The 1st. abdominal segment is longer than the 2nd. ; it is 

 smooth, except the apical third in the centre ; that is raised, 

 keeled on the sides, the keels extending to the middle of the seg- 

 ment ; there is a shorter keel in the centre ; and there are a few 

 irregular transverse stride. Scape of antennse about 4 times long- 

 er than wide, the 3rd. joint slightly longer than the 4th. Face 

 closely, distinctly punctured except in the middle ; clypeus punc- 

 tured, depressed broadly in the middle ; Malar space longer 

 than the antennal scape, depressed down the centre. Mandibles 

 rufous black at apex ; the palpi of a paler rufous colour. Parap- 

 sidal furrows deep, clearly defined. Legs densely pilose; the 

 fore tarsi more than double the length of the tibia?, their basal 

 2 joints being equal in length to them. Temples not quite the 

 length of antennal scape rounded and slightly narrowed.
