teriorly and raised posteriorly; underneath is a sharp 
vertical spine, small. 
Gaster long and narrow, the second segment longer than 
the first, and constricted between. 
Wings as in ?. 
Shining. Mandibles striate; head, including clypeus, 
coarsely reticulate-punctate. Scutum less coarsely so ; the 
Mayrian 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.

8. Length 4°5 mm. 
Rather smaller than the smallest 8 % of metallica. 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 occiput. The occiput has a feeble carina, 
broken in the middle, along its upper border. 
Sculpture similar, except on gaster, of which the first 
segment is covered with transverse striz interspersed 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 shape of the 
occiput, but the sculpture of the gaster is quite distinct.
