86 REVISION OF THE AMYCTERIDKS, ii., 



collections, to West Australian species of the type of T. pustu- 

 latus Pasc; but, in all three cases, the species, to which the name 

 is applied, is not always the same, but differs in the different 

 collections. Furthermore, I have seen specimens belonging to 

 the British Museum, and marked "7'. Roei, compared with type," 

 which represent a quite different species from any so named in 

 Australian collections. The descriptions, though lengthy, would 

 fit several species, and no dimensions are given. Under the 

 cii'cumstances, I have thought it impossible at present to deter- 

 mine the species definitely, and have left undescribed several 

 belonging to the same group, until Bohemann's types can be 

 examined. 7\ hystricosus should be referred, judging from the 

 description, to the same genus as Notonophes spinosus Macl., if, 

 indeed, these names are not synonymous. 



Erichson (Wiegm. Arch, i., 1842), published the descriptions of 

 two new species of Amycterus, both of which were overlooked 

 by Macleay in his paper. Of these two, I have a species which 

 is apparently T. exasperattis; while T. morbillosus is a preoccupied 

 name, and, I believe, correctly placed in Masters' Catalogue as a 

 synonym of T. penicillatus Macl. 



Macleay (Trans. Ent. Soc. N. S. Wales, i., 1865) described, as 

 new, forty-six species, and divided the genus into five sections. 

 Subsequently (Trans. Ent. Soc. N. S.Wales, i, 1866) he added 

 five new species. Of these fifty-one species, I have been able to 

 examine the types of all except, possibly, T. sphcerulatus; but as, 

 in many cases, the species is represented in both the Australian 

 and Macleay Museum Collections, and as the types are unmarked, 

 it follows that it is impossible to say which were the types; and, 

 in all such doubtful cases, I have redescribed the Macleay 

 Museum specimens. T. aberrans is synonymous with T. scaber 

 Boisd.; T. amycteroides with T. catenulatus; T. Camdenensis, 

 T. Murrumbidgetisis, T. i-udis, T. i-uyosus, T. salehrosus with T. 

 bucephalus Oliv.; T. hiscipennis with 7'. impressicollis; 2\ muri- 

 catus{va,Y.) as well as T. fiiicaustus Pasc, and 7'. Macleayi Pasc, 

 (var. = muricatus) with T. incanescens ; T. Mastersi with T. 

 KirbyiW. S. Macl.; 7'. macidattis with T. Riverince; T. nodulosus 

 with T. humeralis; T. Victorice with T, Howitti, T, Howitti
