42 IPHIAULAX AND GHAOLTA; 



Iphiaulax monticola, sp. nov. 



Black, scape of antennae, thorax, except the sides of the 

 metanotum broadly and the front legs red ; the wings dark 

 fuscous, with black nervures and stigma ; the basal 3 abdominal 

 segments longitudinally striated ; the area on base of 2nd seg- 

 ment closely longitudinally striated, longer than broad, not 

 much narrowed towards the apex ; its keel not quite reaching 

 to the apex, bordered by some irregular reticulations, which 

 again are bordered by broadly curved striae ; suturiform articu^ 

 lation crenulated ; the furrow on the base of 4th segment is less 

 strongly crenulated. 9 



Length 15 mm.; terebra 13 mm. 



Hab. Mount Siban. May. 



Scape of antennae about 4 times longer than wide, as long 

 as the 2nd. and 3rd. joints united. Face, except in the centre, 

 sparsely punctured, its centre depressed, the top of the depres- 

 sion with a small tubercle. The middle of clypeus slightly 

 curved downwards ; the sides oblique. Temples slightly oblique, 

 rounded behind, somewhat longer than the antennal scape; 

 occiput not quite transverse. Mesonotum flat. Scutellar furrow 

 narrow, smooth. The raised central part of the 1st. abdominal 

 segment is rugosely punctured at the base ; the apical part has 

 a furrow down the middle with some irregular, stout striae on 

 either side ; the basal lateral depression of the 2nd. segment has 

 a stout, oblique keel in the centre, bordered at the base by 

 some curved striae, those on the outer side being stronger than 

 on the inner ; on the base of the 3rd. segment is a smooth, trian- 

 gular space, bordered, except on the outer side, by crenulated 

 furrows ; the centre of the segment is depressed and there is a 

 furrow down the centre. Second abscissa of radius shorter than 

 the 3rd. Fore tibiae longer than the basal 2 joints of the tarsi 

 united. 



Comes near to 7. pangceus, having, like it, only the basal 3 

 abdominal segments striated ; that species may be known by the 

 temples being more oblique, straight, not rounded ; the 2nd. 

 abdominal segment is not closely striated in the centre at the 

 base ; the middle is not reticulated and all the striae are longi- 

 tudinal, those bordering the keel not being curved.
