Gaster long and narrow, tlie second segment longer than 

 the first, and constricted between. 



"Wings as in $ . 



Shining. Mandibles striate ; head, including clypens, 

 coarsely reticulate-punctate. Scutum less coarsely so ; tlie 

 Mayriau furrows are marked out by broad transverse 

 shining grooves. Rest of thorax and the node coarsely 

 reticulate-punctate, the declivity of epinotum transversely 

 rugose. First segment of gaster faintly reticulate with a 

 few irregular longitudinal lines, second segment more finely 

 reticulate. 



Stipites long and thin, completely encircling the rest of 

 the genitalia.

$ . Length 4'5 mm. 



Rather smaller than the smallest ^ 5 o^nietalUca. Head 

 longer and narrower, hardly wider behind than in front, 

 sides feebly convex. Thorax less robust ; node of pedicel 

 somewhat more pointed in front. Scapes extend a little 

 more beyond the occijmt. The occiput has a feeble carina, 

 broken in tbe middle, along its upper border. 



Sculpture similar, except on gaster, of which the first 

 segment is covered with transverse striae inters[)ersed with 

 punctures which are larger and more numerous than is usual 

 in the type. 



The colour varies from a yellow-brown (palest on thorax), 

 in the majority of specimens, to a metallic green on top of 

 head and thorax and on nearly the whole of gaster. This 

 metallic colour never reaches the depth and brilliance seen 

 in typical specimens of metallica, and there is no trace of 

 purple.

Type in W. C. C. coll. 



According to Emery, this var. resembles the var. cris- 

 tulata, For. (which I have not seen), in the sliapc of the 

 occiput, but the sculpture of the gaster is quite distinct.
