Bah.-— Queensland: Cairns (F. P. Dodd and E. W. 

 Ferguson). Type, I. 2610. 



The uniform colour of the upper-surface, with the entire 

 absence of metallic gloss, will readily distinguish this species 

 from sticticoUis and unilineata, the prothoracic punctures are 

 also more conspicuous (these are denser on each side of base 

 than elsewhere, but towards the sides themselves they are 

 not quite as dense as in the middle) ; but the general outlines 

 and the base of the prosternum are as on those species. 



Stethomela poroptera, Baly. 



S. foveipe?inis, Jac. 



Two specimens in the Blackburn Collection were labelled 

 as pu rapt era, but as they appeared also to agree with the 

 ■description of foveipennis Mr. Arrow was asked for his 

 opinion as to their identity, and it was pointed out to him 

 that, although there were slight differences in the descrip- 

 tions' of the colours of the antennae and legs, the elytral 

 punctures are so very different to those of ordinary species 

 that the differences might well be varietal. In reply lie 

 wrote: — "I think there is no question that these are one 

 species. The antennae are practically the same in both 

 types, and the difference in the legs is of no importance." 



Stethomela stjbmetallica, Baly. 

 Var. fraternalis, Baly. 



The form described as the typical one of this species has 

 the prothorax red, more or less stained with metallic-brown. 

 Such a form- is rather rare. One specimen in the Museum 

 has the prothorax uniformly red and the elytra obscurely 

 diluted with red, but several have the prothorax dark 

 metallic-green, obscurely diluted with red; on others the 

 head (except in front) and pronotum are entirely dark 

 metallic-green. The under-surface, whilst usually reddish, 

 is sometimes metallic-green in parts, occasionally it is almost 

 black, with metallic-green in parts, The punctures usually 

 have a purplish or greenish glitter. 



Var. A. This is perhaps the commonest form of the 

 species. 



Var. B. Possibly described from an immature specimen. 



Var. C, n. var. Bright coppery-green, clypeus, labrum, 

 scutellum (occasionally with infuscate margins), antennae, 

 palpi, and legs more or less reddish, under-surface more or 

 less red, but in places with a metallic-green gloss, or metallic- 

 green, some parts reddish. This is the common form about 

 'Cairns.
