 Bull. Soc. Vaucl. Sc. Nat., vol. 50, p. 245, £ , 1914. 



Tliis differs from the race only in the following trifling details : 

 The colour is lighter, especially the pro-mesonotum ; the legs and 

 antennae are more yellowish ; the nodes are slightly less dull than in 

 the type of the race ; and the sculpture of the thorax and nodes a shade 

 less strong.

" ^ • l"8-2 - 3 mm. Very similar to the Indian species wroughtoni, 

 Forel, but with the head much wider and without the metallic sheen 

 on the abdomen which is seen in that species. Mandibles slightly 

 shining, longitudinally striate, with three strong teeth and posteriorly 

 a very small tooth. Clypeus with two very distinct carinae, which 

 coalesce behind. Head rectangular, hardly longer than wide, feebly 

 concave behind, the sides feebly convex. Eyes convex, fairly large, 

 placed almost within the anterior third of the head. The scape just 

 reaches back to the hind margin of the head. The 3rd-8th joints of 

 the flagellum distinctly wider than long, the 2nd joint as wide as long. 

 Thorax as in salamonis and wroughtoni, but the transition between the 

 two planes of the epinotum more broadly rounded (the two planes 

 indistinctly separated). The two nodes equally high (in salamonis the 

 1st is higher) ; the 1st much wider than in wroughtoni, as wide as the 

 2nd, much wider than its peduncle in front, thicker above than in 

 wroughtoni. Abdomen in front somewhat concavely truncate. Head, 

 thorax and petiole dull ; abdomen slightly glossy in front at the base, 

 shining above and behind, very finely coriaceous and reticulate-rugose ; 

 legs smooth and shining. The head is exceedingly finely and closely 

 longitudinally striate, reticulate-punctate between the striae, the abdo- 

 men anteriorly similarly sculptured, but more feebly. On the head 

 and thorax are some very short, scanty, fine whitish and stiff hairs, 

 not easily observable; similar but longer hairs occur on the petiole 

 and abdomen. In addition there is a fine and short adpressed 

 pubescence, fairly sparse ; scape and legs pubescent only. Brown ;
