206 MEMOIRS OF TEE QUEENSLAND MUSEUM. 



the middle tibia\. and part of the third joint of antenna? are pale ; on one female 

 the seutelhim is rather dark. In my table would be placed with //. anticus 

 and Jf. geniculatus, from each of which it is distinguished by its greater width 

 and purple elytra: in the latter species the antennae are also decidedly longer and 

 thinner; the former species is also considerably smaller, with elytra wider pos- 

 teriorly, and antennae of male entirely pale. 



HETEROMASTIX TARSALIS sp. nov. 

 $ Black ; prothorax, scutellum, parts of under surface of head, 

 mesosternum, and legs flavous; tarsi and sometimes tips of tibiae infuscated. 

 With moderately dense pubescence. 



Head with slight interocular impressions. Eyes rather large and 

 .prominent. Antennae long and rather thin. Prothorax not twice as wide as 

 long, margined throughout ; with submarginal punctures. Elytra moderately 

 wide, almost parallel-sided to near apex, with dense and sharply defined but 

 rather small punctures. Front tihim moderately dilated to, and notched on 

 one side of apex ; basal joint of front tarsi strongly curved on one side. Length, 

 4-5-25 mm. 



llah- — Queensland: Mount Tambourine in December and January 

 (H. Hacker and A. M. Lea) ; National Park (Hacker).— Type, 1. 11875 in South 

 Australian Museum; cotype, C/2302 in Queensland Museum. 



The front legs approach those of H. tibialis, but the notch at the apex 

 of the tibiffi is less pronounced, and the incurvature of the basal joint of tarsi 

 is less ; the elytra are also entirely black. In my table would be placed at F, 

 from all the species of which it is distinguished by its front legs and pale 

 scutellum; in addition H. victoriensis is a narrower species, with much darker 

 legs; //. i)auxiUiis has longer and thinner antennae and black legs; and H. simplex 

 has shorter antenme and darker legs. There are seven males before me, but 

 T have been unable to identify the female amongst the many unidentified ones 

 under examination. 



Var. — A male from the Blue Mountains (in Dr. E. W. Ferguson's collec- 

 tion) structurally agrees with the type, biit has the femora and tibia? (except 

 the knees) infuscated. 



HETEROMASTIX PUSILLIOR sp. nov. 



(J Black; prothorax, two basal joints of antenna?, parts of under surface 

 of head, and knees flavous. With short pubescence. 



Head with two feeble interocular impressions. Antennce long and rather 

 thin, third to eleventh joints subequal. Prothorax about twice as wide as long, 

 margined throughout, lateral margins slightly increasing in width to near apex, 

 where they are slightly thickened; with submarginal punctures. Elytra long, 

 thin, and parallel-sided to near apex; with dense and rather small but sharply 

 defined punctures, becoming smaller at base and apex. Length, 2 mm.
