striated at the base^ and there is a triangular striated part on 

 the sides, the apex extending- to the base of the apical fourth ; 

 there is a keel down the middle of the basal three fourths. 

 Temples as long as the top of the eyes, rounded behind, the 

 occiput almost transverse. Face coarsely rug-osely punctured. 

 Antennal scape about three times longer than wide, of equal 

 width, hardly as long as the second joint of flagellum, not 

 hollowed below. Parapsidal furrows shallow. Recurrent 

 nervure interstitial ; the third abscissa of radius as long as 

 the basal two united. 



Length 10, terebra 17 mm.

In size and form this species resembles /. trichiotkecus. 

 Cam. ; the latter may be known by the third and fourth 

 abdominal segments being striated. /. e.vtraneus, Cam., has 

 the same abdominal striation, but is a much larger and stouter 

 species, and may be readily separated by the different form of 

 the abdominal plate, which is much longer, gradually nar- 

 rowed to a point near the middle of the segment. 



Iphiaulax eriopJioruSj sp. n. 



Black ; tlie head (except the sides and top of front) and the 

 vertex (except the sides behind, and the hinder central part 

 more narrowly, which are black) dark rufous ; the antennal 

 flagellum black ; the prothorax bright red ; the depression 

 bordering the basal plate of second abdominal segment, its 

 apex broadly in the centre, narrowly on the sides, the centre 

 of the third and fourth segments broadly at the base and apex, 

 more narrowly in the middle, and the greater part of the 

 ventral surface, rufo-testaceous. Median segment and breast 

 thickly covered with white woolly pubescence, that on the 

 latter shorter than on the former. The fore legs and the 

 middle knees broadly rufo-testaceous. Wings hyaline, very 

 iridescent, slightly tinged with fuscous; the costa, stigma, 

 and nervures deep black. ? .

Abdominal segments to near tlie apex of the fourth finely 

 closely striated ; the first segment broad at the base, raised, 

 the sides depressed ; the area on the base of second not very 

 clearly defined, striated, narrowed gradually towards the apex, 

 which extends to near the end of the segment ; the sur- 

 rounding parts are much more strongly striated; there is a 

 curved furrow on the sides of the third segment and a trans- 

 verse crenulated one ou the apex. Face covered witli white
