shagreened and punctured. The clypeus is more narrowed above and 

 more strongly carinate, and covered with numerous piligerous pits. 

 The prothorax is narrow and pyriform, and, like the mesothorax, is 

 much longer than wide. The structure of both these segments and 

 also of the epinotum and scale differs but little from that of the 

 $ minor." 



y minor, 15*5-16 mm. Head 3-5-4 mm. long by 2-2*2 mm. wide, 

 scape 5*5 mm. long, the posterior femur 6 mm. Varying from pale 

 brown with the abdomen umber brown and the femora pale yellowish 

 brown, to entirely dark brown or blackish brown and the coxae 

 ochreous. The flagellum in all cases ferruginous. Sometimes the 

 clypeus, anterior half of the thorax and the basal two-thirds of the 

 femora are more or less ferruginous. Dull, the anterior third of the 

 head with a slight gloss. Head very finely and closely reticulate- 

 rugulose. Thorax, petiole and abdomen finely rugulose. Pubescence 

 fine, yellowish, decumbent and very scanty, on the abdomen ex- 

 ceedingly fine. Anterior margin of the clypeus with a fringe of 

 porrect, yellowish bristles ; cheeks in front with a few short exserted 

 hairs, abdomen with a basal and a marginal row of yellowish brown, 

 coarse and oblique hairs on each segment ; on the 1st segment the 

 basal row is wanting. Tibiae strongly compressed or prismatic, with 

 a very oblique row of setae below. Head from one-half to four-fifths 

 longer than wide, parallel-sided in front of the eyes, trapezoidal 

 behind them, the sides converging rapidly towards the articular 

 border. Apart from the articular border, there is no hind margin. 

 The anterior margin of the head is from two and a third to three times 

 wider than the articular border. Mandibles triangular, 7-dentate, very 

 finely striate and subopaque. Clypeus carinate, with a wide and 

 very short lobe, the anterior margin of which is straight and crenulate. 

 Flagellum and scapes very long ; the tip of the flagellum extends back 

 to the base of the 3rd abdominal segment, the scape reaches the 

 meso-epinotal suture. Frontal carinae long and fairly close together. 

 Thorax low, feebly convex lengthwise, narrow and long. Pronotum 

 not very convex transversely, sloping obliquely forwards and some- 

 what flattened lengthwise. Mesonotum not much narrowed behind, 

 one-third longer than wide. Metanotum obsolete. Dorsum of the 

 epinotum rounded transversely, fairly wide, at least two and a half 

 times longer than wide and much longer than the very short declivity 

 which it joins in a low curve. Scale of petiole subcorneal, the dorsal 

 edge not trenchant, hardly higher than long. Abdomen oblongo- 

 ovate. Legs very long and slender.
