Tins species may be at once distinguished from its congeners 

 known to me by the very conspicuous and remarkable sculpture 

 of its prothorax, consisting of close strong more or less longi- 

 tudinal wrinkles or striae. It has been sent to me on what I 

 cannot but admit to be valuable authority as A. tnaurulus, Pasc. 

 I cannot however think it can be that insect seeing that Mr. 

 Pascoe calls its prothorax " impunctate " and says nothing about 

 any strigse on that segment. I have seen many specimens of 

 this species, all quite identical. 



N. S. Wales ; apparently widely distributed. 



The following are the species of Amarygmus described since the 

 publication of Mr. Masters' Catalogue of Coleoptera and before 

 the date of this revision. 



A. DiAPERioiDES, Blackb., P.L.S.N.S.W. 1888, p. 1435. 



A. TARDUS, Blackb., loc. cit. 1889, p. 1271. 



A. UNiFORMis, Blackb., loc. cit. 1889, p. 1272. 



N.B. — The insect of which the following is a description has 

 been received while this memoir was in the press, and therefore 

 can be noticed only as an addendum. 



A. Tasmanicus (? var. imiformis, Blackb.). 



A. uniformi, Blackb., valde affinis ; differ fc magnitudine majori, 

 colore obscure viridi (nullo modo aeneo). Long. 7, lat. 34 lines. 



This is an extremely puzzling species owing to its great 

 resemblance to A. uniformis (from N. Queensland). A careful 

 comparison with the type of the latter has failed to reveal any 

 very satisfactory character to distinguish it; nevertheless, its
