especially on the head ; but as the female only of trifur is 

 known and the male only of pernix, there is a possibility 

 that they are opposite sexes of the same species. Ceropales 

 parva, Cam., -which closely resembles X albovariegata in 

 colour, does not belong to the same genus, but I do not 

 think that it is correctly placed in Ceropales, the eyes being 

 without emargiuation. 



Xanthampulex albovariegata, Cam. 



Ceropales alhovariegata, Cam. Mem. Maucb. Lit. & Phil. Soc. xli. p. 84 

 (1896). 



This species is mentioned, but without a name, bv Schulz 

 (Zool. Annal. iv. p. 145, 1911). 



I cannot agree with Schulz as to the position of this 

 genus, which I look on as closely allied to Ceropales in the 

 structure of the pronotum and the emarginate eyes. The 

 median segment is very unlike any of the Ampulicinse, with 

 which group Schulz connects the genus, and the frontal 

 prominence is not similar in form to that in DoUchurus.

$ . Nigra ; tegulis, tarsis iutermediis et anterioribus, tibiisque basi 

 testaceis ; segmentis abdominalibus primo apice secundo lateribus 

 ferrugineis. 



? . Clypeus covered with dense, fine, silver pubescence, 

 more than twice as broad as long, the anterior margin very 

 slightly rounded and shallowly emarginate in the middle, 

 moderately convex and with a very obscure carina from the 

 base to the apex. Antennae inserted nearly twice as far 

 from each other as from the eyes, and separated from the 

 base of the clypeus by a distance equal to half the length of 

 the clypeus, the first joint of the flagellura very short, partly 

 concealed in the apex of the scape, less than one quarter of 

 the length of the second joint, which is more than half as 

 long again as the third joint, the apical joints thickened but 

 all much longer than broad, the whole antenna about equal 

 in length to the thorax and median segment combined. 

 Head shining, sparsely and very finely punctured, a very 

 short longitudinal carina between the antennse, the eyes 

 separated on the front by a distance equal to twice the length 

 of the scape. Thorax shining and sparsely punctured ; the
