on the upper inner half, a mark on (he upper basal half of the mesopleura?, narrowed 

 to a point above, a small spot below it, followed by a line, reaching to the sternum, 

 an irregular mark in the centre of the latter, a large mark on the apical half of the 1st 

 abdominal segment, the mark dilated on the inner side at the base, from which it be- 

 comes gradually widened, broad bands, narrowly separated in the middle, gradually nar- 

 rowed from the outer to the innerside, on the 2nd, 3rd, 4th and 5th, the lines becoming 

 gradually narrower, a wider line, hardly narrowed in the centre; and broad lines on the 

 apices of the 2nd, 3rd and 4th ventral segments, yellow; the last segment entirely, the 

 greater part of the basal 2, the 3rd and 4th narrowly, before the yellow lines and the 

 5th and 6th, ventral segments rufous. Antennas and legs rufous, the 10th and llth 

 antennal joints black, the hinder coxa 1 , trochanters and base of femora their basal 

 third below yellow. Wings hyaline, the apex narrowly fuscous, the costa and stigma 

 fulvous ; the pedicle of 2nd cubital cellule not quite so long as the posterior nervures 

 which are roundly curved; the recurrent nervure is received near the apex of the basal 

 fourth; the 2nd recurrent at the same distance beyond (he 2nd transverse cubital nervure. 

 Metanotal area strongly closely punctured like the rest of the metanotum. o 71 . 



Length 13 mm. 



Mem low lands, Ngare na nyuki. 25th November. 



The last joint of the antenna 3 is roundly curved and is as long as the preceding 

 2 united and thinner than them. Apex of clypeus broadly, roundly curved, the sides 

 fringed with golden hair; the clypeus and face weakly punctured, the upper part of the 

 face more distinctly than the lower. Front, vertex and thorax closely, strongly punctured, 

 as is also the abdomen. 1st abdominal segment is not much longer than it is wide at 

 the apex; pygidium, except at base and apex, strongly, but not closely punctured; apex 

 of hypopygium roundly depressed. 



Cerceris erythroura, sp. nov. 



$: Black, the antenna 1 , the clypeus, face, the lower half of inner orbits broadly, 

 the outer broadly above, narrowly below, basal two-thirds of mandibles, the apex of 5th 

 abdominal segment narrowly above, entirely below, the whole of the 6th, apical three 

 fourths of anterior femora, the apical two-thirds of the middle, the apical projection on 

 the posterior and the tibia? and tarsi, red; a narrow line on the sides of the apex of 

 pronotum, post-scutellum, a broad line, narrowed in the middle on the 1st abdominal 

 segment, a narrow line on the sides of the 2nd, a broad continuous one on the apex 

 of the 3rd and a narrower continuous one on the apex of the 4th, yellow 7 . Wings hyaline, 

 iridescent, the costal, radial and cubital cellules smoky violaceous, the radial darker than 

 the others, the costa and stigma rufo-fulvous, the nervures black; the 2nd transverse 

 cubital nervure longer than the 1st, the pedicle shorter than the 1st; the recurrent nerv- 

 ure received at the apex of the basal fourth. Metanotal area obliquely striated, the 

 stria? clearly separated, the apex is more strongly and closely transversely striated, the 

 rest of the metanotum more closely punctured than the mesonolum or scutellum on
