POLYPHRADES GRANICOLLIS, Lea. 



Some specimens of this species (from Mount Lofty and 

 Port Lincoln) are very small (ranging down to 3 mm.), and 

 three of these from Mount Lofty have the elytral setae less 

 depressed than usual ; others are slightly larger than the 

 types. In general appearance the species is fairly close to 

 jrictus, except that the average specimen is less brightly 

 coloured, but on abrasion the head is seen to be non-strigose, 

 except to a slight extent in the immediate vicinity of the 

 eyes. 



POLYPHRADES BASALIS, 11. Sp. 



Black, appendages in parts obscurely diluted with red. 

 Densely clothed with light-brown scales, paler on sides and 

 about base of elytra than on disc, under-surface of body and 

 of legs with white scales; with fairly numerous setae, becom- 

 ing dense (but depressed) on elytra. 



Rostrum very short and wide, on an almost even plane with 

 head, and scarcely depressed and non-carinated along middle, 

 inter-antennary space very wide; apical plate short, notched 

 in front. Scape stout, short, and lightly curved ; basal joint 

 of funicle almost as long as second and third combined, fourth 

 to seventh transverse. Prothorax almost twice as wide as 

 long, sides gently rounded; with small dense granules, readily 

 traceable before abrasion. Elytra subovate, sides rather 

 strongly rounded, suddenly narrow T ed at base; with regular 

 rows of large, deep punctures, appearing small through 

 clothing. Tibiae lightly denticulate ; claws not quite even. 

 Length, 6-6| mm. 



Flab. — Northern Territory: Darwin (H. Wesselman). 

 Type, I. 5591. 



In general appearance fairly close to females of 

 basirostris, but space between scrobes much greater, eyes less 

 convex, and base of rostrum and of elytra different; the 

 much wider space between the scrobes also distinguishes the 

 species from collaris and ampliatus. On the front of the 

 rostrum and on parts of the legs the scales have a more or 

 less golden lustre; there are some small patches of sooty- 

 brown scales on the sides of the elytra. From some directions 

 the rostrum is seen to have a small glabrous triangle, but it 

 is not conspicuously elevated above the adjacent parts and is 

 not joined to a median carina ; seen directly from in front 

 or behind its triangular shape is not at all evident, whereas 

 on most species the apical triangle is quite conspicuous from 

 any point of view. The two specimens before me are probably 

 females. 



A specimen from East Kimberley (Inspector Stephens) 

 appears to belong to this species, but differs in being smaller
