and apical segment of abdomen reddish brown ; the coxae piceous, 

 the tarsi dark red. The whole body covered with an exceedingly 

 fine pruinose pubescence, similar to that of the Platythyreini ; 

 there are a few long hairs on the clypeus, and the apical segment of 

 the abdomen is densely clothed with moderately long golden hairs. 

 Head, scape of antenna, thorax, femora, tibiae, petiole, 1st and 2nd 

 abdominal segments microscopically rugulose, and excepting the 

 antennae and legs closely punctured with small, shallow punctures ; 

 the 3rd and 4th abdominal segments very finely punctured. Head 

 trapezoid, wider in front than behind, posterior margin slightly 

 emarginate, posterior angles very round. The eyes occupy a little 

 more than one-quarter of the sides of the head, and are placed far 

 forwards and separated from the base of the mandibles by less than 

 their own length. Clypeus shining and coarsely punctured, the 

 anterior margin membranous and translucent, with a feebly crenate 

 depression just in front of the membranous area ; the median portion 

 very slightly raised, not carinate, projecting backwards between the 

 frontal carinae. The latter are narrow, not divergent behind, 

 separated along their posterior half by a narrow sulcus which is 

 continued back to about the level of the middle of the eyes. 

 Antennae reach back as far as the base of 1st abdominal segment, 

 the scape reaches back as far as the middle of the pronotum. 

 Mandibles very long, linear, acute at the apex, finely striate and 

 shining. Pronotum about as long as wide, rounded in front, sides 

 moderately convex. Pro-mesonotal suture distinct. Mesonotum 

 hardly more than half as wide as the pronotum, and considerably 

 less than half as long. Dorsum of epinotum widening towards the 

 declivity and as long as the pro- and mesonotum together ; declivity 

 shallowly excavated, the lateral margins raised. Node of petiole sub- 

 quadrate, very slightly wider than long, rounded above, vertical in 

 front and behind ; ventral lamella bluntly produced at the extreme 

 base. Abdomen elongate, 1st segment as high as, and one-third 

 wider than the node, spinously produced below at the base ; 1st and 

 2nd segments sub-equal, their apical margins narrowly ferruginous. 



" $ . 2f lines. Black and slightly shining, finely punctured; 

 eyes and ocelli very large, the latter glassy bright and very promi- 

 nent ; the legs and antennae fusco-ferruginous ; the antennae 

 towards their apex, the articulations of the legs, the tarsi and tip of 

 abdomen ferruginous ; wings fusco-hyaline ; abdomen and node of 

 peduncle as in the female (= worker)." 



I have not seen any $ $ of this species, and have therefore copied 

 Smith's very scanty description. It is not a common species ; the
