the upper-surface frequently has a golden lustre, but it varies 

 to stramineous or ashen ; the dark elytral pubescence is so 

 disposed that the paler clothing at the base and on the suture 

 forms an ornamental T ; the dark pubescence on most of the 

 specimens is quite black, but on others varies to a golden- 

 brown, but always leaving a conspicuous T ; it is narrowly 

 advanced on each side to the extreme base ; the pale sutural 

 pubescence is quite regular and parallel-sided till it abruptly 

 disappears at about one-sixth from the apex. The pubescence 

 on the scutellum is usually darker than on the adjacent parts, 

 and there is sometimes a slight stain on the pubescence towards 

 the middle of the base of the pronotum. 



On the head, prothorax, and elytra of this, as also of the 

 following species, the punctures are very dense and minute, 

 but concealed except where the derm is exposed. 



Pelecotomoides hackeri, n. sp. 



Blackish, parts of antennae and of legs of an obscure 

 brown. Densely clothed with short pubescence, greyish on 

 head, prothorax, scutellum, and on a wide subtriangular 

 basal portion of elytra, black on the rest of elytra, greyish on 

 under-surface and legs. 



Antennae moderately stout, third joint almost as long as 

 fourth and fifth combined, these subequal in length, but fifth 

 slightly wider than fourth, sixth-tenth rather strongly ser- 

 rated. Length, 7-8 mm. 



Hab. — Queensland: Buderim Mountain, April, 1912 (H. 

 Hacker). Type in Queensland Museum; co-type, I. 5923, in 

 South Australian Museum. 



Another very distinct species, although the general out- 

 lines are almost exactly as on the preceding one, but the third 

 to fifth joints of antennae are somewhat differently propor- 

 tioned, and the elytral clothing is different. The black 

 pubescence on the elytra (although uniformly dark) has a 

 curiously mottled appearance, and in some lights a dark rusty- 

 brown gloss ; it leaves a subtriangular space at the base 

 (extending from the shoulders to the suture at about the basal 

 fourth) on which the pubescence is similarly coloured to that 

 on the prothorax, and is exactly alike on the four specimens 

 under examination. 



CANTHARIDAE. 



ZONITIS LONGICEPS, n. Sp. 



Flavous ; tips of elytra, antennae, palpi, tarsi (claws ex- 

 cepted), apical half of tibiae, and tips of femora black or 

 blackish. Upper-surface (except parts of elytra) glabrous, 

 under-surface and appendages finely pubescent.
