coalescing from the suture to the centre of the disk with the broader part 
of the anterior band, but leaving exposed along the suture a sub-triangular 
patch of the background ; the anterior band is shaped as in salisburiana, 
but very nearly connected behind with the posterior the shape of which 
is similar to that of the variety above-mentioned, but a little wider towards 
the margin. 
Length 15 mm. ; width 5 mm. 
Hab. Southern Ehodesia (Salisbury).

Plate XXIV., fig. 101. 
Sculpture and vestiture of the preceding varieties ; on each elytron 
the basal dorsal lunule has invaded the whole basal part except for a small 
quadrate black patch below the scutellum, and has become entirely con- 
nected with the anterior band suffusing thus with yellow the anterior half, 
the hind margin of that yellow suffusion emits a short spur along the 
suture, and is bi-denticulate from the centre to the outer margin, the 
posterior band is narrow and greatly attenuated and deeply bi-incised on 
each border from the centre to the outer margin. 
Length 13J mm. ; width 6 mm. 
Hab. Southern Ehodesia (Umtali). 
Var. LYDENBUKGIA, 
Plate XXIY., fig. 102. 
In this variety the basal dorsal lunule has also invaded the whole 
anterior part, but there is a median dorsal small spot of the background 
showing at about one-third of the length, and the spur emitted near the 
suture is very narrowly connected at a short distance from it with the 
posterior band the shape of which is similar to that of the variety 
rhodesiana, but is wider. 
Length 17 mm. ; width 7 mm. 
Hab. Transvaal (Lydenburg). 
Yar. JOHANNis, 
Plate XXIY., fig. 103. 
Yery distinct from all the varieties of D. lunata. The pubescence is 
black, as in the type form, and there is also no silky flavescent patch of 
hairs above the apex of the elytra ; the sculpture is, however, identical. 
The basal dorsal lunule is slightly elongate arcuate but does not reach the 
suture ; the anterior band is of equal width, but very narrow and narrowly 
interrupted above the outer margin, the hind border is more sinuate
