96 REVISION OF SYMPETES AND HELjEUS, ETC., 



Ser.2, Vol.ii., p.649) and which I have closely examined in the 

 Macleay Museum, It is labelled H. echinatus Macleay, N.S.W. 

 I have specimens exactly like it from Mount Macedon and other 

 parts of Victoria. The edges of the elytra are thin, as in H. 

 ovatus Guer., those of the prothorax wide and upturned. The 

 tubercles of the elytra are larger than in H. tuberculattcs Breme, 

 the short scutellary costa is nodulose or broken, and the large 

 seriate punctures are more evident than in the other species. 

 The form is in general narrower than in H. tuherculatus. The 

 'figure given by Hope is of little use for distinguishing the main 

 points of difference between this and the other species. 



H. horridus Blackb., is not aptly named, since horridus 

 suggests spines, while the description evidently refers to 

 "tubercles" only, on the elytra. These tubercles are larger 

 than in any of the preceding. I have three specimens, taken by 

 myself near Mt. Kosciusko, which correspond to Mr. Blackburn's 

 description. The author only states of the locality that " the 

 South Australian Museum possesses a single specimen, probably 

 taken in South Australia." The extreme edges of the prothorax 

 and elytra are as in H. ovatus Guer., and H. echinatus Hope.
