rouuded. As iu the $ , the clypeiis projects in the t'orui of a 

 rounded lobe, tlie paJpi are much longer. The frontal lamina; 

 a])pear to be w anting, 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 iiicrassate, the 2ud 

 joint very small, transverse, the following nuich longer (the -jrd 

 joint is about three times as long as the scape and the l^nd joint 

 iinited). 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 oifers some traces of the regular sculpture which 

 is so marked in the ^ , interiorly iu 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 Foucrido:, two 

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

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

 line sericeous pubescence, particularly dense on the antennie 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, 

 autennal laminie covering the base of the antennae, very broad ; 

 head above the clypeus regularly and somewhat coarsely striate, 

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

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

 notum with transverse striae above, curved longitudinal strife on 

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

 metanotum striated in elongate concentric loops from base to apex ; 

 legs densely pruiuose and pubescent. Node of the pedicel with 

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

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

 wai-ds), 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 pohshed.
