Emenadia interioris, Blackb. 



A female (from Sydney, in coll. Lea) agrees well with 

 the description of this species, except that the abdomen is 

 partly black; the legs of the type were not specially men- 

 tioned ; on the Sydney specimen the femora and coxae are 

 black, the other parts being of a dark red. 



Another specimen (from Caloundra, in the Queensland 

 Museum) agrees perfectly in structure with the Sydney speci- 

 men, but differs in colour of legs and under-surface ; the 

 elytra are narrowly black at the base, except that the shoulders 

 are red, and each has a large subtriangular median black 

 spot, the space at its sides and between it and the apex being 

 of the same' shade of red as the shoulders, between the spot 

 and the black base the colour is almost flavous ; less of the 

 sterna and abdomen are black, and the femora are black only 

 at the apex. This specimen appears to connect interioris with 

 maculicollis. 



Emenadia cucullata, Macl. 

 Var. pictipennis, Lea. 



From an examination of sixteen specimens I am convinced 

 that the form named pictipennis is only a colour variety of 

 cucullata. The following forms are before me : — 



1. Elytra entirely black. 



2. Each elytron with one reddish spot, the spot usually 

 rather obscure. 



3. Each elytron with two reddish spots, the spots obscure 

 on some specimens, very distinct on others, and gradually 

 increasing till they are conjoined (Form 4). 



4. On this form the two pale markings are considerably 

 enlarged and conjoined, and enclose a large dark spot ; the 

 apex of the elytra is also pale ; the other parts of the elytra 

 vary from quite black to dark reddish-brown (as on the types 

 of pictipennis). 



All the specimens of Forms 1 and 2 are females, all of 

 Form 4 males, of Form 3 there are both sexes. The feature 

 used by Blackburn to distinguish the species in his table of 

 the genus, "Prothorax bearing a longitudinal median carina, " 

 is sometimes very feeble, and should not be relied upon. 



Emenadia diversiceps, Blackb. 

 On this species, which is widely distributed in South Aus- 

 tralia, the medio-basal lobe of the pronotum is either lightly 

 notched or truncate. Four specimens from New South Wales 

 (Sydney, Galston, Forest Reefs, and Bindogundra) and one 

 from Western Australia (Darling Ranges) differ from some co- 

 types, and other South Australian specimens, in having the
