in certain lights the head is seen to be minutely longitudinally 

 striate, the pronotura just as minutely but transversely striate : 

 pilosity very sparse, only a few erect hairs on the front of the head 

 and apex of the abdomen ; pubescence somewhat dense, but very 

 short and inconspicuous on the scape of the antennae and tibiae of 

 the legs. Head longer than broad; mandibles shining, narrow, the 

 masticatory margin armed with 4 teeth ; clypeus convex in the 

 middle, slightly shining, the carinae obtuse; antennae short, the scape 

 not extending to the top of the head ; eyes a little below the middle 

 of the sides of the head. Thorax anteriorly broad, narrowing 

 posteriorly, the anterior margin of the pronotum arched, the 

 anterior lateral angles of the thorax a little pronounced ; meso- 

 metanotal suture slight ; basal face of raetanotum long, narrow, 

 compressed, convex, passing into the apical portion by a rounded 

 curve, and bearing an impression giving the posterior lateral angles 

 of the metanotum an appearance of being subtuberculate. Pedicel : 

 1st node conical, anteriorly shortly petiolate ; 2nd node broader 

 than long and above much broader than the 1st ; abdomen elon- 

 gate, oval.

$ . Head, thorax and node of pedicel fuscous or blackish brown, 

 abdomen dark brown; the abdomen except at base smooth and 

 shining, the remainder densely and finely rugulose, opaque ; pilosity 

 very sparse, the antenna? and legs entirely without erect or oblique 

 hairs. Head longer than broad, narrow posteriorly, slightly emar- 

 ginate ; mandibles smooth, armed with 4 teeth ; clypeus obscurely 

 and obtusely bicarinate, the carinae slightly projecting anteriorly ; 

 antenna) moderately long, the scape nearly reaching the top of 

 the head; eyes lateral, proportionately rather large, very little 

 below the middle of the head. Thorax somewhat depressed, sub- 

 margined ; the pro-mesonotura only very slightly convex, the 

 meso-metanotal suture distinct but not 'deeply impressed, the 

 thorax barely emarginate at the suture ; basal portion of meta- 

 notum rectangular, apex truncate. Pedicel : 1st node somewhat 

 conical, rounded above, anteriorly petiolate, the petiole thickening 

 aud sloping posteriorly to the node ; 2nd node globose, broader 

 than the 1st node ; abdomen depressed, somewhat broadly oval, 

 truncate anteriorly, acute posteriorly.
