Head, thorax and nodes dull, closely and finely reticulate-punctate 

 (granulate), the nodes more shallowly so than the rest of the body. 

 Abdomen and legs smooth and shining. Mandibles nitidulous, feebly 

 striate. Head, excluding the mandibles, one-sixth longer than wide, 

 oval. Eyes convex, fairly large, placed in the middle of the sides. 

 Frontal carinae parallel ; frontal area depressed and shining. Clypeus 

 with a feeble median carina, the anterior margin entire and convex. 

 The pronotum is rather long, very little shorter than wide, the 

 posterior angles feeble. Mesonotum with a wide transverse impres- 

 sion ; in most specimens the anterior margin of the mesonotum is 

 slightly raised in the middle. Meso-epinotal sutui'e deep. Dorsum 

 of epinotum much longer than wide, a little longer than the oblique 

 declivity, longitudinally sulcate in the middle. Epinotal teeth acute, 

 vertical, very small, and hardly longer than their basal width. 

 Dorsal edge of 1st node rounded and thick; 2nd node subconical or 

 hemispherical, widest at the posterior fourth, behind which point it is 

 rather abruptly contracted, but without forming sharp lateral angles. 

 Abdomen oblong. Legs long, the femora a little swollen. 



$ . 105 mm. (hitherto undescribed). Black, the head sometimes 

 paler or piceous, the mandibles dark castaneous brown, the flageHum 

 and tarsi ferruginous. Pilosity and pubescence as in the 1/ . Head 

 dull, the sides closely reticulate-punctate and with large longitudinal 

 rugae superimposed, the vertex longitudinally striato-rugose, the 

 spaces between the striae rugulose. The occipital groove is distinctly 

 defined and transversely ribbed, or clathrate, ending at the anterior 

 ocellus. Mesonotum rugulose, with a shallow and longitudinal 

 rugosity superimposed ; a small anterior median area and the borders 

 of the parapsidal sutures smooth and shining. Paraptera longi- 

 tudinally rugose. Scutellum and metanotum finely and transversely 

 rugulose, the former slightly shining in the middle. Epinotum 

 shining, the sides sparsely and coarsely rugose, the declivity finely and 

 superficially reticulate. Nodes dull, reticulate-punctate and rugose ; 

 the rugae on the 2nd node transverse. Basal fourth of 1st abdominal 

 segment dull and reticulate, the extreme base with a few short rugae, 

 the rest of the abdomen smooth and shining. Head, excluding the 

 mandibles, about one-seventh wider than long, widest behind, the 

 sides convergent anteriorly, the posterior margin concave. Eyes 

 placed in front of the middle of the sides. Clypeus as in the 1/. 

 Mandibles feebly striate but more strongly punctured than in the 1/ . 

 The scapes extend back as far as the posterior ocelli. Head barely 

 wider than the mesonotum. The latter almost one-third wider than 

 long. Dorsum of epinotum obsolete between the teeth, the declivity
