joint scarcely longer than third and at apex no wider, second about half the 

 length of third, third-ninth subequal in length and apical width, tenth distinctly 

 wider and with a small spine at inner apex, eleventh longer than ninth and 

 tenth combined, base irregularly compressed. ProtJiorax more than twice a.s 

 wide as long, distinctly margined throughout. Elytra parallel-sided to near 

 apex; with crowded and small rugulose punctures, and vague remnants of costae. 

 Length, 6-5 mm. 



Hah. — Queensland: Mount Tambourine (H. J. Carter). — Type, 1.11861 

 in South Australian Museum. 



In my table would be associated with H. lundicoUis, but distinguished 

 from that, as from all other species having the apical joints of antennae distorted, 

 by the black prothorax and bicolorous elytra. The eleventh joint of antennjp 

 appears to alter in shape with the point of view; from one direction it appears 

 to have a subbasal notch and to be narrower than the tenth joint ; on its under 

 surface it has a short longitudinal groove which appears to be continued on to 

 the tenth; the spine on the latter joint, although small, is quite distinct from 

 above. 



Var. — Another male, from Mount Tambourine (taken by Mr. Hacker and 

 in the Queensland Museum), has the prothorax entirely pale, the black part 

 of its elytra is slightly advanced near the suture, and decreased towards the 

 sides; as a result it appears to have an almost circular outline. A female (taken 

 by Mr. Carter), also with flavous prothorax, differs from the male in the usual 

 particulars of antennce, legs, and abdomen. 



HETEROMASTIX MELANOCEPHALUS sp. nov. 



^ Black; prothorax, basal two-thirds of elytra, tibiae, parts of femora 

 and of tarsi, and three basal joints of antenna? flavous. With moderately dense 

 pubescence, varying in colour with the derm. 



Head gently convex between eyes (these rather small and prominent), 

 slightly depressed in front. Antennae moderately long, second joint very short, 

 tenth and eleventh distorted. Prothorax almost twice as wide as long, margined 

 throughout, the lateral margins somewhat thickened near apex. Elytra almost 

 parallel-sided to near apex; with dense and small, rugulose punctures. Length 

 ((?$), 4-4-5 mm. 



9 Differs in having the head smaller with shorter and somewhat thinner 

 antennae, tenth joint similar to the ninth, and their combined length slightly 

 less than the eleventh, only about one-fourth of the elytra black, legs somewhat 

 shorter, and abdomen not notched.
