9 • Differs m being more robust, head with crowded 

 punctures except at extreme base, where only are they 

 individually distinct, clypeus more transverse, club of 

 antennae less parallel-sided and only about two-thirds of the 

 length of front tibiae, prothorax with larger and more numer- 

 ous punctures, and the larger claw of the front tarsi 

 conspicuously cleft at apex. 



Hab. — Queensland: Cunnamulla (H. Hardcastle). 



Close to S. collaris, and like that species in general appear- 

 ance strikingly resembling several species of Aneurystyjms t 

 (to which genus collar is was originally referred by Blackburn), 

 but the male differs in being consistently larger and with 

 different punctures on the head ; on the present species the 

 punctures from the clypeal suture to the base are all sharply 

 defined, and non-confluent ; on collaris they are crowded and 

 confluent behind the suture, but become isolated towards 

 the base, the differences being pronounced between five males 

 of each species; there are other slight differences of the 

 antennae and legs. In general appearance and structurally 

 it is close to S. weiskei, but without the least metallic gloss, 

 the prothorax smaller and with larger punctures, those on the 

 head larger and clypeus less strongly narrowed in front. From 

 S. villosus it is distinguished by its glabrous upper-surface 

 and from the description of S. felschei by its very different 

 colour. Mr. Hardcastle obtained numerous males at lights, 

 but only one female. 



DASCILLIDAE. 



Macrohelodes. 



The species of this genus are usually very variable in 

 colour, and to a certain extent in size; Tasmanian specimens 

 are also usually larger, and frequently darker than mainland 

 ones of the same species. 



Macrohelodes lucidus, Blackb. 



The type of this species was described as having the 

 upper-surface black, except for the narrowly reddish suture 

 of elytra. Of two cotypes in the Museum one is of a very 

 dark brown, with a slight bluish gloss, and the suture some- 

 what paler, but the second specimen is paler. Other specimens 

 vary from a rather bright-castaneous to almost black, w T ith 

 the suture uniform in colour with the rest of the upper- 

 surface. The species may be readily distinguished from all 

 others by its polished and almost impunctate elytra, and by a 

 small marginal fovea at the basal third of each elytron (not 

 mentioned in the original descriptions). It occurs from 

 Nelson, in Victoria, to Stradbroke Island, in Queensland.
