62 P. CAMERON. 



Straight on the inner side, rounded ou the outer, and narrowed beneath ; the lower tooth 

 is broadly rounded ; the lower somewhat triangular. The labrum in the middle is smooth 

 and shining, bare and broadly keeled, the keel being broadest on the top. The sides and 

 base of the mesonotum are closely punctured, as is also the scutellura, except at the base. 

 The median segment is more closely and strongly punctured ; the basal area is clearly 

 defined ; its base is longer than the sides ; it is aciculated and obscurely furrowed down 

 the middle. The hair on the legs is long, dense and deep black. Wings uniformly deep 

 violaceous, with some blue tints at the base and apex ; the third transverse cubital nervure 

 is obliquelj' sloped at the top and bottom ; the two parts are of equal length and form 

 a sharp angle in the middle ; the lower part has a more sharply oblique slope. Abdomen 

 smooth and shining; sparsely punctured, except at the base where the punctuation is closer 

 and stronger; there is a smooth furrow down the middle of the apical segment; the 

 middle of the last apical segment is smooth and keeled towards the apex. 



This species comes near X. gardineri, but is not, I feel sure, its $ ; as, apart from 

 the difference in the coloration of the base of the wings, it differs from it in some 

 structural points; the area on the median segment is longer, much broader compared to 

 its length and it is glabrous and impunctate ; the thorax wants the white pubescence ; 

 it is smaller and the abdomen at the base is not hollowed : it is distinctly longer than 

 the head and thorax united. The spine on the outer side of the four hinder tibiae is broad 

 at the base, bluntly pointed at the apex; that on the front pair is smaller, more curved 

 and more sharply pointed.

Scape of antennae not dilated towards the apex, slender. Head opaque, thickly covered 

 with short black hair and closely and distinctly punctured, except at the sides of the hinder 

 ocelli and the apex of the clypeus. Eyes not converging on the top, parallel. The front 

 ocellus is surrounded by a deep furrow. Clypeus flat ; the oblique lateral furrows are not 

 clearly indicated. The base of the mandibles is sparsely punctured ; the apical tooth is 

 broadly rounded at the apex ; it is short, not much longer than broad. Labrum obliquely 

 depressed, closely and rather strongly punctured and with a smooth furrow down the centre, 

 which is broadest at the top. The sides and base of the mesonotum are covered with 

 pale hair; the centre is bare. Except in the middle the mesonotum is closely and minutely 

 punctured. The scutellum is sparsely punctured at the base, closely and more strongly
