the 2nd and following abdominal segments, which are feebly shining. 

 The body and the femora very closely and finely reticulate-punctate, 

 almost granular. The reticulations are closer and finer on the 

 abdomen and nodes, more open and coarser, but still very fine, on 

 the sides of the thorax. In addition to this fundamental sculpture, 

 the head has a few fine longitudinal striae in the middle, which do 

 not reach quite as far as the occiput behind, but extend over the 

 clypeus in front. The sides of the head, below and in front of the 

 eyes, are also finely and widely reticulate-rugose. The anterior half 

 of the pro-mesonotum has a very distinct and wide reticulation 

 superimposed. 



Head, excluding the mandibles, slightly longer than wide, the sides 

 almost straight or very feebly convex, the hind margin straight. 

 Scrobes absent. Eyes rather small, distinctly angulated in front 

 below, placed in the middle of the sides. Frontal carinae short, 

 divergent, not reaching the middle of the head. Clypeus with a 

 feeble median carina, the anterior margin angularly excised in the 

 middle. The scapes extend back as far as the posterior sixth of the 

 head, 2nd-8th joints of the flagellum wider than long, the club not 

 thick. Mandibles dull, very finely and closely striate, armed with 

 3 teeth in front and 4 very small ones behind. Thorax in front not 

 quite as wide as the head, the sutures obsolete, not much constricted 

 between the meso- and epinotum. Shoulders of the pronotum fairly 

 prominent, but rounded. The thorax in profile is feebly convex above, 

 with the anterior portion of the pronotum vertical. The meso- and 

 epinotum feebly marginate at the sides. The dorsum of the epinotum 

 is twice as long as it is wide at the base, where it is Avidest, and twice 

 as long as the oblique declivity. The epinotal teeth are very small, 

 shorter than their basal width, hardly as long as the episternal teeth, 

 but more pointed. The 1st joint of the petiole resembles very closely 

 that of subcoecum, var. inscia, but the peduncle is broader. The 2nd 

 node is semicircular, wider behind than in front, and wider than 

 the 1st. Both nodes have traces of fine rugae on the dorsal surface. 

 Legs entirely dull, femora not much swollen. 



$ . 2'8 mm. Brownish-black; tarsi, flagellum, and apical half of 

 the abdomen brownish-yellow ; mandibles yellow, scapes, tibiae, and 

 femora yellowish-brown. Pilosity and pubescence as in the £' , the 

 pilosity almost entirely absent from the head. Head, thorax, nodes, 

 and basal third of the 1st abdominal segment very closely and finely 

 reticulate-punctate and dull, the sculpture on the head very fine. 

 The declivity of the epinotum marginate at the sides, and with some 

 wider reticulations superimposed. The apical two-thirds of the 1st
