This is probably a variable species in size and coloration ; the blue 
or violaceous tints vary in intensity ; the alar nervures may be black or 
testaceous ; only the basal (scape) joint of the antennae may be rufo- 
testaceous, or the basal six or seven may be so coloured. Saint Fargean 
calls the coloration of the basal antennal joints “ luteous ” ; in my 
examples they are distinctly rufo- testaceous ; the amount of the rufous 
coloration on the clypeus and mandibles varies, and it may be suffused 
with black. In one male the fore tarsi are luteous, with the base of the first 
joint black ; Magretti’s var. rufo-pictus has the oral region and the thorax 
red.

only ; the mandibles are usually entirely red ; the blue body colour may 
be variegated with violet or green.

Black ; the antennae reddish-brown below ; the four front tibiae 
tinged with brown ; the abdomen above distinctly tinged with blue- 
violaceous ; wings fuscous- violaceous ; the stigma and nervures black ; 
the second abscissa of the radius a little shorter than the first, and half 
the length of the third ; the second cubital cellule small, along the radius 
hardly half the length it is along the cubitus ; the first recurrent nervure 
received shortly before the middle, the second almost interstitial, received 
very shortly beyond the transverse cubital ; clypeus short, half longer 
than it is wide, about half the length of the labrum ; its apex transverse, 
depressed ; labrum smooth, shining, bare ; the apex of clypeus fringed 
with long hair ; apex of pronotum with a distinct rounded incision in the 
middle ; metanotum finely, closely striated, more strongly on the outer 
edge than on the centre ; the upper part of the metapleurae strongly, 
obliquely striated; abdominal petiole twice longer than wide. Female.
