? , especially on the petiole and abdomen ; there are also a few long, 

 erect, and blackish hairs on the thorax. The rugulosity of the 

 surface is much stronger than in the $ ; the posterior half of the 

 head is strongly and rather closely punctured. The mesonotum is 

 sparsely but coarsely punctured. The head is slightly shining on the 

 vertex, the rest of the body dull. Head longer than wide, sides rather 

 convex, posterior margin nearly straight, wider behind the eyes than 

 in front. The eyes occupy about two-thirds of the sides of the head, 

 and are placed a little in front of the middle. Ocelli large, on a 

 slightly raised area. Mandibles shining, feebly and sparsely punc- 

 tured, armed with 5 teeth. Clypeus feebly convex transversely, with 

 an obtuse median tubercle. Scape of antenna two and one-third times 

 as long as the 1st joint of the flagellum, not reaching back to the 

 posterior third of the eyes. First joint of flagellum very short, about 

 as long as wide, all the remaining joints very much longer than wide; 

 the antenna reaches back as far as the base of the 2nd joint of the 

 petiole. Pronotum exposed above, short, convex transversely. Meso- 

 notum a little longer than wide, with the scutellum a little longer than 

 the head. The epinotum is somewhat flattened, the dorsum and 

 declivity not distinctly delimited ; it is widest at the base, and about 

 as long as wide. First joint of petiole with a short peduncle, the 

 node twice as long as wide ; 2nd joint conical, widest behind, not 

 quite half as wide again as the 1st joint. The petiole is not margi- 

 nate.

It is necessary to sink this form to the rank of a variety of 

 obscurata, from which it differs only in the following characters : 



£ . 6 mm. The colour is lighter, especially on the thorax and front 

 of the head. The posterior half of the head is dark brown, contrast- 

 ing sharply with the ochreous anterior half. The pronotum is wider ; 

 the epinotum is much less strongly punctured, and the node of the 

 1st joint of the petiole a little narrower and less convex. 



? . The eyes are a little longer. The pronotum is also a little 

 longer and more sharply margined, and anterior angles less rounded. 

 As in the $ , the colour is generally paler than in the type of the 

 race, but the promesonotal suture has a dark blackish spot in the 

 middle, and the parapsidal sutures are also heavily margined with
