Lateral angles of the pro-mesonotura obtuse and not prominent, 

 pro-mesonotal suture obsolete ; mesonotum with a feeble transverse 

 torus, not depressed in front of the same, vertical behind it. Dorsum 

 of epinotum as long as wide between the spines, the latter relatively 

 shorter than in our other species Of the sculjoturata group, erect, 

 triangular, as high as they are wide at the base. Declivity of epinotum 

 subvertical, a little longer than its dorsum. Petiole shaped exactly 

 like that of Liengmei, race micrartifex. 



^ . 2 - 6 mm. Head piceous, excepting the anterior margin and the 

 clypeus, which are yellowish -brown. Thorax reddish-brown (burnt 

 umber), abdomen dark brown, antennae, femora and tibiae brown, 

 bases and apices of the femora, tarsi and mandibles brownish-ochreous. 

 Pilosity yellowish, oblique, fairly scanty, but more abundant than in 

 micrartifex Forel. Mandibles, clypeus, legs and abdomen fairly 

 shining, the rest dull. Head and thorax closely and evenly reticulate- 

 punctate, the pronotum with two or three median longitudinal striae 

 on the disc, and finely and longitudinally aciculate on the posterior 

 half of the sides ; petiole superficially reticulate, abdomeu smooth. 



Head oval, one-fifth longer than wide, the sides moderately convex, 

 the posterior margin straight. Mandibles sparsely but very finely 

 punctured and with a few longitudinal aciculations, with seven teeth. 

 Anterior margin of the clypeus convex, finely but distinctly carinate 

 in the middle. Frontal area triangular, large and well defined. Eyes 

 placed in the middle of the sides of the head. The scapes extend 

 beyond the posterior margin by one-seventh of their length. Frontal 

 carinae nearly parallel. Pronotum strongly convex, with barely 

 defined posterior lateral angles. Pro-mesonotal suture arcuate, indi- 

 cated by a fine raised line. Mesonotum transversely and shallowly 

 impressed in front of the middle. Dorsum of epinotum horizontal and 

 flat, one and a-half times longer than wide, the spines acute, short, not 

 longer than their basal width, directed vertically upwards. Node of 1st 

 joint of the petiole obtuse above, hardly as long as wide ; 2nd joint of 

 petiole as long as wide, its anterior margin convex, obtusely angulated 

 in the middle of the sides, but not dentiform or spinose.
