$ . 3'6 mm. Head, antennae, legs, thorax and petiole bright orange 

 red, abdomen brownish, with more or less of the median portion of the 

 1st segment yellowish red, apices of the tarsi and the mandibular teeth 

 brownish. Head, thorax and posterior faces of the nodes finely granu- 

 late, posterior portion of the clypeus and frontal carinae finely and 

 longitudinally striate, the sides of the thorax more strongly granulate 

 than the dorsum. Abdomen smooth and shining. There is a very fine 

 and short pubescence on the head ; the petiole and abdomen have a 

 few long and sub-erect hairs. Head, excluding the mandibles, a little 

 longer than wide, the sides feebly convex. Frontal carinae short and 

 parallel. Eyes situated at about the middle of the sides of the head. 

 Mandibles finely and longitudinally striate, with 4 distinct teeth. 

 Scape long, extending back well beyond the occipital margin, 1st joint 

 of flagellum one- third longer than the 2nd. Thorax narrower than 

 the head ; pronotum convex in front and at the sides, a little wider 

 than long, pro-mesonotal suture faintly indicated ; mesonotum as long 

 as the pronotum, longer than wide, meso-epinotal suture deep ; dorsum 

 of epinotum flat, quite as long as the mesonotum and merging 

 gradually into the declivity. The 1st joint of the petiole has a 

 short peduncle, much shorter than the node ; the latter is obtusely 

 conical, and about as long and as wide as the 2nd node. Seen in 

 profile, the 1st node is half as high again as the 2nd. Legs long and 

 slender. 



? . 6"3 mm. Dark yellowish red (burnt sienna), with almost a 

 fiery golden reflection in some lights. Pronotum, mesopleura, sides of 

 the mesonotum, a median spot behind the pro-mesonotal suture, the 

 basal half of the 2nd and following abdominal segments brownish, 

 femora and scape more or less brownish. There is a very sparse and 

 pale pubescence on the whole body, with a few long, pilose hairs on the 

 clypeus, petiole and abdomen. Head and thorax very finely and 

 longitudinally rugoso-striate, the head also somewhat reticulate- 

 punctate ; the declivity of the epinotum and the posterior dorsal 

 portions of the nodes transversely and more strongly rugose. Abdo- 

 men very finely and longitudinally striate, the basal halves of the 2nd 

 and following segments microscopically coriaceous, and slightly shining. 

 Head sub- quadrate ; the eyes convex, situated a little behind the 

 middle of the sides. The dorsum of the epinotum merges gradually 

 into the declivity. The epinotum is shallowly concave transversely 

 from base to apex. The 1st node of the petiole is strongly compressed 

 from front to back, so as to form a fairly sharp and convex dorsal 

 edge ; the anterior face of the node is almost vertical, the peduncle 

 very short. The 2nd node is slightly wider than the 1st, and sub-
