" Iphiaulax varitinctus, sp. nov. 



Vermilion-red ; the abdomen largely suffused with dull yellow^ 

 the red showing only in patches ; the antennae, front, vertex, and 

 occiput black. Wings fuscous, with the usual hyaline spots below 

 the stigma ; the costa and stigma red ; hind tarsi black ; the tibiae- 

 and tarsi are paler than the femora. $ . 



Length 12 mm. ; terebra 5 mm. 



Cape. 



Antennae longer than the body ; the scape oval, twice longer than 

 it is wide in the middle, densely pilose. Face smooth, sparsely 

 haired, black iu the middle ; the inner orbits are narrowly lined with 

 red ; the black from the vertex extends, except close to the eyes, ta 

 the middle of the eyes. The middle of the first abdominal segments, 

 the second, and the third to near the apex, and the transverse furrows 

 are closely, strongly striated ; the furrows on the apices of the thii'd, 

 fourth, and fifth are narrow, distinct, and obscurely crenulated. 

 Palpi black. 



Comes close to I. inctus, B6. ; that may be known by the black 

 face, by the outer orbits being broadly black throughout, rufous, not 

 black palpi and finely punctured — not smooth — apical segments of 

 the abdomen, and by the paler, lead-coloured abdomen. In the latter 

 respect it resembles I. rubrinervis ; that species has the eye orbits 

 widely red, the mesonotum with three large black marks, and the 

 pleurae are for the greater part black. 



Iphiaulax decorus, sp. nov. 



Red ; the antennae, apex of mandibles, head, except for a spot 

 opposite the antennae, two spots on the hind orbits, lower part of 

 prothorax, mesopleurae, except the part above the oblique furrow 

 below the tegulae, the lower part of the base, continued on to the 

 edge of the sternum, the median segment, three large marks on 

 the mesonotum and a large mark on the base of the hinder coxae,, 

 black. Wings smoky, the costal cellule, second cubital cellule, and 

 a cloud on the outer side of the recurrent nervure more hyaline in 

 tint ; the costa and stigma, except at the apex, red ; the nervures 

 black. ? and J •
