find the head, sterna, and femora, invariably black or pitchy- 
black. The prothorax varies from entirely testaceous red, 
through forms in which the disc is diversely marked with fuscous 
or blackish, to a form in which it is entirely black. The elytra 
vary from a rare form in which they are entirely testaceous 
except a slight infuscation round the middle part of the base, 
through forms in which the whole base is black or blackish with 
that colour extended, more or less widely, for a greater or less 
distance along the suture, to forms in which the sutural blacken- 
ing is extended to fill up the whole apical quarter. The number 
of antennal joints having their base testaceous (the rami of the 
male and the serrations of the female are invariably blackish) is 
variable. The hind angles of the prothorax are somewhat 
strongly divergent. 
E. tricolor, Gerstack. I have not seen any specimen that I can 
refer to this species, which is described as having the head and 
prothorax and the under surface red. Although the Hmenadice 
are extraordinarly variable in the colours and markings of the 
prothorax and elytra, J have not seen (even in some fairly long 
series) any variation in the colour of the head in any species. 
Gerstacker evidently had at least more than one specimen of 
tricolor before him, so that his description cannot have been 
founded on an isolated extreme aberration of a species usually 
having the head black. Mr. Waterhouse (Ann. Nat. H., 1883) 
describes a black-headed male Hmenadia, which he says is pro- 
bably the male of tricolor, and supposes the difference of colour 
to be sexual. JI have not seen any specimen coloured as that 
male is described, but I can say positively that in no Hmenadia, 
of which I have seen both sexes, is there a sexual difference of 
colour, and I have little doubt that the male in question is dis- 
tinct from tricolor, and also from the other named Emenadie. 
In Mr. Masters’ Catalogue, ‘South and W. Australia,” is cited 
as the habitat of Z. tricolor, but I notice that Gerstacker gives 
the habitat merely as ‘‘ Nova-Hollandia.”
