206 A LIST OF THE CUCUJID^ OF AUSTRALIA, 



After carefully examining a series of more than sixty examples 

 belonging to the genus Hectarthrum I have come to the conclusion, 

 notwithstanding their great variation in size and sculpture, that 

 only one species is at present known from Australia. I, therefore, 

 fully endorse Grouvelle's opinion that the thi-ee forms described 

 under the above names are varieties of one species. 



The specimens before me vary from 7 to 23 mm. in length. 



Ancistria. 

 Erichson, Nat. Ins., III., p. 305, (1845.) 



3. Ancistria retusa. (^A.M.) 



Ancistria retusa, Fabricius, Syst. El., II., p. 555. 

 Priono2)hora cylindrica, Westwood, Cab. Orient. Ent., p. 85, pi. 

 41, fig. 6. 



Cape York, North Australia ; Tasmania. 



It is very possible that the specimens from Tasmania will prove 

 to belong to a distinct species, as they differ slightly in punctuation 

 from the form which has hitherto been regarded as the typical A. 



retusa. 



Prostomis. 



Latreille, Eegn. Anim., p. 397, (1825.) 



The Prostomis laticeps, Macleay, is allied to if not congeneric 

 with Mimemodes of Reitter (Deutsche Ent. Zeit, 1876, p. 296), 

 and must be referred to the family Monotomidse. Mr. Macleay 

 has compared his species with the figure of Reitter's M. 

 monstrosum (Wien Ent. Zeit, 1884, pi. lY.), kindly forwarded to 

 me by my friend Mr. George Lewis, and agrees with me in con- 

 sidering them pi'obably members of the same genus. 



4. Prostomis Atkinsoni. (A.M.) 



Prostomis Atkinsoni, Waterhouse, Ent. Mo. Mag., XIY., p. 26, 

 (1877.) 



Tasmania ; Alps of Yictoria. 



I think it probable that too many species have been described 

 belonging to the section of the genus having the sides of the
