rounded. As in the , the clypeus projects in the form of a 

 rounded lobe, the palpi are much longer. The frontal laminae 

 appear to be wanting, that is to say, they are reduced to a raised 

 margin on the inner side of the insertion of the antennae ; these 

 are elongate with the scape large and somewhat incrassate, the 2nd 

 joint very small, transverse, the following much longer (the 3rd 

 joint is about three times as long as the scape and the 2nd joint 

 united). The eyes are large and elongate. The thorax is destitute 

 of parapsidal furrows ; the metanotum is unarmed, feebly impressed 

 along the median line. The pedicel has the form of an elevated, 

 somewhat gibbous node, without teeth or spines above. The speci- 

 men from Java offers some traces of the regular sculpture which 

 is so marked in the , interiorly in both specimens it is armed 

 with a tooth on its anterior margin. The abdomen is distinctly 

 constricted between the 2nd and 3rd segments ; the pygidium is 

 produced into a long spine incurved at base, on both sides of which 

 project as two cerci the external genital valves ; the hypopygium 

 is rounded. The wings have, as in the rest of the Poneridce, two 

 closed cubital and one discoidal cell." (Emery.)

$ . Black, with a fairly abundant erect pilosity and dense yellow- 

 fine sericeous pubescence, particularly dense on the antennae and 

 legs. Head broad, very rounded and convex posteriorly ; mandibles 

 punctured, not striate, strongly dentate ; clypeus convex, the 

 median lobe pinched and raised at base, rounded anteriorly, 

 antennal laminae covering the base of the antennas, very broad ; 

 head above the clypeus regularly and somewhat coarsely striate, 

 the striae longitudinal in the middle of the front, inclined obliquely 

 inwards at the sides. Thorax narrower than the head ; the pio- 

 notum with transverse striae above, curved longitudinal striae on 

 the sides ; mesonotum narrow, fairly distinct, opaque not striate ; 

 metanotum striated in elongate concentric loops from base to apex ; 

 legs densely pruinose and pubescent. Node of the pedicel with 

 concentric striae, much higher than broad or long, flat posteriorly, 

 convex in front, (viewed from the front the sides are arched out- 

 wards), narrowed at base and apex, nodal spines moderately far 

 apart, short, and pointing upwards ; abdomen, except for the 

 pubescence, smooth and shining, with a metallic-blue reflection in 

 certain lights, the basal segment highly polished.
