fine pruinose pubescence, the apical margin rather broadly covered 
with pale ochreous tomentum; mandibles black; cheeks anteriorly 
(next to orbits) covered with dense white hair, but posteriorly with 
thinner hair; posterior ocelli unusually close together, the distance 
between them about equal to the diameter of one; mesothorax bare, 
shining, very strongly and densely punctured, the punctures mostly in 
longitudinal grooves; scutellum rugose, slightly emarginate apically, 
base with two short transverse stripes of white pubescence; axillar 
teeth long and pointed, strongly punctured; tegule black; wings 
fuliginous, with strong violaceous tints, hyaline basally ; legs (with 
spurs) black ; abdomen shining, not densely punctured, segments with 
narrow pure white hair-bands, enlarged at sides; last dorsal segment 
delicately keeled throughout its length, the apex pointed ; last ventral 
extending some distance beyond last dorsal lanceolate, not notched at 
sides; penultimate ventral segment dull and finely granular except at 
base. 
Type; Bluff, Durban, 6th April, 1917 (C. N. Barker). Co-type, 
with abdominal bands spoiled. Durban, 22nd April, 1916 (E. C. 
Chubb). The apex of the abdomen is formed much as in C, brevis, 
Eversm., but the last, ventral is broader, and not nearly so long. 
Superficially, C. chubbi resembles C. durbanensis, Ckll., but the end 
of the abdomen is entirely different.

with snow-white hair; cheeks densely white-hairy ; distance between
