than broad. Head smooth and shining, the face thickly covered 

 with long white hair ; temples 1)i-oad, slightly, roundly obliquely 

 narrowed ; front with an oblique slope, furrowed in the centre : 

 tips of mandibles black : palpi pale red, thickly covered with 

 white hair. Thorax smooth and shining : the pleune, breast and 

 metanotum thickly covered with white hair. Abdomen distinctly 

 broader than the thorax, as long as it and the head united : the 

 raised central part of the 1st segment with 4 stout longitudinal 

 stria? ; the depressed lateral part smooth, wide : the 2nd to 5th 

 segments are coarsely, closely rugosely punctured, their furrows 

 deep and crenulated, wider and cui-ved at the sides ; there is no 

 area on the base of 2nd segment, which is irregularly longitudi- 

 nally striated ; the 3rd to 5th are smooth laterally at the base : the 

 5th has the apex produced at the sides. The 3rd abscissa of the 

 radius is longer than the basal two united ; the 2nd transverse 

 cubital nervure is bordered by a nari'ow hyaline cloud : the basal 

 lobe of mesonotum is hardly raised : the scape of antennae is 

 pi'oduced into a short, sharp tooth at the apex below. 



My only example wants the ovipositor. The species is related 

 to I. pictus, Be, and /. incisus. Be.

Length 13, terebra 24 mm; 



Front and vertex smooth and shining : the former deeply 

 furrowed down the middle ; face rugosely punctured, irregularly 

 reticulated ; the sides bordered by a keel. Clypeus depressed in 

 the middle, flat, the sides raised. Palpi i-ufo-testaceous, thickly 

 covered with white hair ; the apical joint of maxillarj' black. 

 Thorax smooth and shining ; the mesonotum fiat. Abdomen 

 twice the length of the head and thorax united ; the basal 4 seg- 

 ments closely, coarsely longitudinally striated ; the 2 basal longer 

 than wide ; the 3rd and 4th almost scjuare ; the basal half of 1st 

 roundly convex ; the 2nd with a longish, almost smooth depression 

 on the sides near the apex ; the 4th with a less distinct depression. 

 There is no area on the base of the 2nd segment ; on its base is a 

 small smooth space, dilated obliquely in the middle.
