112 Mr. P. Cameron on New Species 



very iridescent, the stigma pallid yellow, the basal nervures black, 

 the apical pallid fuscous. $ . 



Length 7 ; terebra 1 mm. 



Antennae perceptibly thickened towards the apex ; the scape 

 rufous below. Face closely punctured, more strongly in the middle ; 

 the clypeus at the apex with shallow, scattered punctures ; the front 

 and vertex closely and not so strongly punctured. Mandibles 

 yellowish-testaceous, the teeth black ; the palpi pallid yellow. 

 Mesonotum closely punctured ; the scutellum almost smooth. Median 

 segment coarsely punctured, the middle transversely striated at the 

 sides ; the basal central area slightly wider than long, obliquely 

 narrowed towards the apex, the areola semicircular, nearly as wide 

 as long, aciculated laterally ; the teeth blunt, stout ; the posterior 

 median area of nearly equal width throughout, its base rounded. 

 The apex of the pro- and the mesopleurse closely and strongly punc- 

 tured, the meta- for the most part closely, obliquely and strongly 

 striated. Petiole smooth, the apex aciculated ; the gastrocoeli trans- 

 verse, shallow, pale testaceous, the segment behind them obliquely 

 striated. 



The $ wants the white and red marks on the meso- 

 jileurai ; the hinder femora are black at the apices, the 

 tibice are for the greater part black ; the hind coxas broadly- 

 black at the apex ; the white mark on the antennas is 

 smaller and their apical joints are dilated beneath. 



Mesostenus respondens, sp. nov. 



Black ; the 6th to 15th joints of the antennae beneath, the face, 

 clypeus, except at the sides, labrum, base of mandibles, palpi and 

 the outer orbits — broadly on the lower-side — white ; a broad line 

 on the pronotum, a mark on the apex of the middle lobe of the 

 mesonotum, the scutellums, a broad line round the apex of the 

 mesonotum — narrowed above, the lateral part appearing triangular 

 thi'ough being gradually narrowed below, — the tubercles, a small 

 mark on the apex shortly above the middle, a large mark on the 

 lower-side, triangularly narrowed at the apex. A crescent-shaped 

 mark immediately under the hind-wings, an oblique, conical mark 

 on the metapleurae and the apices of the abdominal segments 

 — the basal two broadly, the penultimate still more broadly, the 

 central narrowly, — yellow. Legs rufo-fulvous, the four front coxte 

 and trochanters pale yellow, the hinder pale fvilvous above and 

 with a somewhat triangular black mark in the centre, the apex of 

 the hinder tibife, the extreme base of the tarsi and their apical joint
