I/. Head, thorax and pedicel castaneous red; abdomen dark 

 brown, nearly black, with the apical margins of the segments 

 reddish yellow ; pilosity pale yellowish, short but abundant. Head, 

 thorax and abdomen dull and opaque, the front of the head 

 anteriorly and the metanotum coarsely striate, the striae on the 

 head posteriorly breaking into coarse reticulations ; thorax more 

 finely punctured and reticulate, abdomen finely and somewhat 

 slightly longitudinally striate. Head and abdomen exceedingly 

 large, globose, the former constricted in front, very wide posteriorly, 

 the occipital emargination proportionately shallow and slight, the 

 lateral lobes very large, rounded and convex above ; mandibles 

 smooth, sparsely finely punctured ; clypeus medially emarginate, 

 and with a medial vertical short and somewhat thick carina; 

 antenna3 very short ; the scape, flattened and laterally margined on 

 the upper side, falls short of the top of the head by about its own 

 length, antennal grooves divergent, rather narrow and shallow. 

 Thorax narrow in proportion to the very large and massive head 

 and abdomen ; pronotum and mesonotum rounded, convex, the 

 transverse groove and ridge on the latter very slight ; metanotum 

 cubical, the basal portion flat, margined on the sides and broadening 

 posteriorly ; the metanotal spines comparatively short, erect and 

 acute. Pedicel : the 1st node squamiform, deeply emarginate above, 

 almost bidentate, beneath with a translucid laminate and rounded 

 lobe ; 2nd node much wider than the 1st, transversely fusiform 

 and coarsely reticulate-punctate above; abdomen massive, very 

 convex, above as broad as long, and as long as the thorax and 

 pedicel united. 



$ . Shining yellowish brown all over ; pilosity sparse, smooth 

 except on the meso- and metanotum, which are somewhat closely 

 and delicately punctured. Head broadly oval, eyes prominent, 

 occiput rounded and convex ; mandibles with the basal half flat and 

 narrow, suddenly broadening towards the masticatory margin ; 

 antennae long, comparatively slender, the scape passing beyond the 

 top of the head by nearly half its length. Thorax elongate, the 

 pronotum raised and convex; the meso- and metanotum oblique, 

 the transverse furrow on the former wide, nearly obsolete, the 

 metanotum unarmed. Pedicel moderately long; the 1st node
