Belus acaciae, Lea. 

 A specimen from Swallow (Central Australia) possibly 

 represents a variety of acaciae, but differs from the types in 

 being slightly more robust, prothorax with sides more dilated, 

 and spots of clothing on elytra more numerous and better 

 denned. 



Belus vertebralis, Lea. 



A specimen from Charters Towers (Queensland) differs 

 from the types in being without a nude spot on each meta- 

 sternal episternum, its whole surface being densely and 

 uniformly clothed. 



Belus plagiatus, Pasc 



On specimens from New South Wales and Southern 

 Queensland, of this species, the subapical spots of the elytra 

 are elongated and there are several small spots about the 

 middle; but on specimens from Northern Queensland the 

 subapical spots are almost circular, and the median spots are 

 wanting. 



Belus vetustus, Pasc. 



A specimen from Ooldea possibly represents a variety of 

 vetustus, it differs from typical specimens in having the 

 elytra with fewer setae scattered singly, the pronotum with 

 the dorsal channel more conspicuously interrupted in middle, 

 and with looser clothing, the abdomen (except at the sides) 

 without distinct glabrous spots (these are sometimes but 

 faintly indicated on otherwise typical specimens), and with 

 the pubescence in five feebly denned stripes : a median and 

 two lateral snowy ones, the others stramineous. 



B. anguineus, Pasc, Ooldea. 



B. filiformis, Germ., Orroroo. 



B. phoenicopterus, Germ., Orroroo. 



B. serpens, Pasc, Parachilna. 



B. suturalis, Boi., Ooldea, Orroroo, Parachilna. 



Belus interruptus, n. sp. 



Dark castaneous-brown, becoming almost black on parts 

 of head and of legs; antennae and tarsi somewhat paler. In 

 places densely clothed with more or less stramineous 

 pubescence. 



Head with coarse vermiculate punctures between eyes, 

 becoming smaller but still crowded about base. Rostrum long 

 and lightly curved; with dense and fairly coarse punctures 

 on basal half, becoming smaller towards, and very fine in 

 front. Antennae rather long, third joint slightly shorter than 

 first and fourth and conspicuously longer than second,
