top, is a black mark, which is dilated below on the lower side ; 

 the base of the hinder tibiae, the extreme base of the tarsi and 

 their apical joint, black ; the apices of the four anterior claws are 

 black. Wings hyaline, the apices of both smoky ; the nervures 

 and stigma black ; the areolet triangular, slightly appendiculated ; 

 the recurrent nervure is I'eceived almost in the middle. 



" Length 16 mm."

Cameron says {Joe. cit. p. 163) that this species is very similar to 

 X. ijedator ; but may be known from it by the marks on the meso- 

 notum being smaller, by the abdomen being impunctate, the petiole 

 longer compared with the second segment and by the two basal 

 segments not being centrally canaliculate ; the areola is not trans- 

 verse nor constricted from its centre ; and the apical lateral arese 

 are said to be broader, compared with the basal. I have seen the 

 typical female in the British Museum, which is very probably 

 nothing but a form of X. pedator, F.

5 . A flavous, impunctate species, similar to X. Ihasiana. 

 " Head yellow ; the occiput except at the sides, the ocellar region 

 and the front in the middle, black ; the black on the front gradually 

 narrowed to a point at the apex, dilated at the base ; the face 

 closely punctured ; the sides bluntly keeled to near the apex, 

 which is only obscurely punctured ; the clypeus smooth ; the tips 

 of the mandibles black. AnteancB longer than the body, black ; 

 the extreme apex rufous; the basal three joints yellow beneath. 

 In the middle of the mesonotum is a cup-shaped black mark, the 

 narrow basal part being as long as the dilated apical, which, at the 

 base, is roundly incised ; the lateral marks as long and as wide as 

 the dilated part of the central ; they are narro\\ed gradually to a 

 point at the apex ; the base on the inner side transverse ; on the 

 outer, obliquely truncated ; the central area and the base of the 

 median segment distinctly broader than it is long; the lateral 

 keels straight, slightly, but distinctly, diverging towards the apex ; 

 the apical keel slightly and gradually curved ; the basal lateral 

 keel large, not much wider on the outer side ; the apical oblique, 

 considerably widened from the inner to the outer side ; the meso- 

 pleural tubercles large, sharply projecting ; the middle below them 

 also projecting, but not so acutely. iSctdellum pyramidal, smooth ; 

 looked at from behind it is somewhat triangular, with the sides 

 straight, smooth, impunctate, and covered rather thickly with long, 

 fuscous hair ; the keel on the lower side leaf-liUe, large; the keel 

 on the sides of the postscutellum narrow. Abdomen shining, im- 

 punctate ; a black mark on either side of the second, third, and 

 fourth segments, those on the second slightly smaller, more 

 irregular and not so square, and a transverse band, narrowed in
