case they prove it to be one of the most variable of its family. 
Among them there are hardly two to be found strictly identical 
in colouring or sculpture. The greater part of them appear from 
the labels to have been taken at one place (Toowoomba) and on 
one plant (Hugenia). As most of them would be quite unrecog- 
nisable by comparison with my description of the type form, I 
think it will be best to describe them as being probably varieties 
of 8. Koebelz, as follows :— 
Var. ? immaculatus a, S. Koebelz, differt elytris immaculatis. 
Var.? Hugenie a, 8S. immaculato, differt pedibus (tarsis exceptis) 
totis capiteque nigris. 
Var. ? fulvohirtus a 8. immaculato, differt pedibus totis capiteque 
nigris, corpore supra fulvo- (nec cinereo-) hirsuto. 
var.? varipes a S.immaculato, differt tibiis (presertim anticis) plus 
minusve rufescentibus, elytris obsolete punctulatis magis 
nitidis (nonnullorum exemplorum corpore supra _ fulvo- 
hirsuto). 
An example differing from the typical form only in the some- 
what stronger sculpture of its elytra and under surface and its 
more darkly coloured head and legs I take to be a typical female. 
A remarkable character in S. Koebela is the exceptionally strong 
dilatation of the elytra immediately behind the base, which causes 
the lateral margin to be very strongly sinuate about the middle.
