Myllocerus darwini, Blackb. 



Three specimens from the Daly River (Northern Terri- 

 tory) are structurally so close to darwini that I cannot regard 

 them as representing more than a variety of that species, but 

 their legs and antennae are almost entirely red. 



Another specimen from the Daly River apparently 

 represents another variety ; it has the appendages partly dark, 

 but the scales entirely white or whitish. 



Myllocerus quadricolor, n. sp. 



Black, appendages reddish. Densely clothed with bright 

 green scales, but becoming almost white on appendages; a row 

 of depressed pale setae on each elytral interstice. 



Head flat between eyes, with a narrow median fovea. 

 Eyes strongly convex. Rostrum slightly wider than long, 

 carinae normally concealed. Antennae rather long and thin, 

 first joint of funicle no longer than second. Prothorax 

 moderately transverse, sides increasing in width to extreme 

 base, convex along middle but widely depressed towards each 

 side of middle; punctures normally concealed. Elytra 

 conspicuously wider than prothorax, sides almost parallel to 

 beyond the middle ; with rows of rather large punctures, 

 appearing much smaller and suboblong through clothing. 

 Femora lightly but acutely dentate. Length, 4-4| mm. 



Hab. — Northern Territory: Darwin (G. F. Hill and 

 W. K. Hunt). Type, I. 4090. 



A small species belonging to B of the 1914 table of the 

 genus, and there associated with longus; from which it differs 

 in size, shape, antennae, impressions of prothorax, etc. It 

 looks very out of place amongst the species of B, but the 

 base of the prothorax is conspicuously wider than the apex. 

 The scales on the elytra of the type are uniformly green, but 

 on a second specimen there are a few feebly inf uscated spots ; 

 on the second specimen also the impressions on the pronotum 

 are deeper, so that it appears to be rather conspicuously 

 bifoveate. 



Myllocerus viridimicans, n. sp. 



Black; appendages reddish. Densely clothed with bright 

 green scales, becoming almost white on antennae and parts of 

 legs; a single row of very inconspicuous setae on each elytral 

 interstice. 



Head feebly convex and with a small interocular fovea. 

 Eyes subelliptic and moderately convex. Rostrum moderately 

 long, median and sublateral carinae traceable through 

 clothing. Antennae thin and rather long; scape narrowly 

 grooved along under-surface ; first joint of funicle distinctly
