Antennae rufous, blackish above, the scape black. Head some- 

 what strongly punctured, thickly covered with white pubescence, 

 longest on the face. The inner eye orbits are margined in the 

 middle. Thorax closely and strongly punctured. Areola longish, 

 horseshoe-shaped, longer than broad, rounded behind, its apex 

 transverse; it is finely, closely obliquely striated, the strige con- 

 verging towards the centre ; the sides at the apex are depressed, 

 and not so distinctly striated ; the lateral basal arese are strongly, 

 closely punctured ; the apical transversely striated, the spiracular 

 rugosely reticulated ; the metapleurae more or less obliquely 

 striated. Petiole covered with long white pubescence ; the post- 

 petiole closely punctured on the sides ; the centi-e smooth at the 

 base and apex, the middle punctured, strongly but not closely ; 

 the other segments closely punctured, pilose ; gastrocoeli large, 

 the outer side with two stout keels. Areolct 5-angled, the recurrent 

 nervure received near the base of the apical third ; transverse basal 

 nervure interstitial ; the disco-cubital neither angled nor broken, 



Platylabus nigripalpis, sp. nov. 



Black, the apex of the clypeus, the line broadest on the sides, the 

 inner and outer orbits narrowly, a short line on the apex of 

 the pronotum, the base of the keels at the base of the scutellum,

 strongly rugosely punctured ; the areola longer than wide, 

 roundly narrowed at the base, the apex almost transverse ; it 

 is closely, irregularly longitudinally reticulated-striated ; the
