416 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



mandibles bifid at the apex, viz. convexus, Pasc, exilts, Pasc, 

 foveolatus, Macl., striatus, Mad., torridiis, Pasc, tyrrhenus, Pasc, 

 variolaris, Pasc, tardus, Blackb., uniformis, Blackb., diaperioides, 

 Blackb., and (although my identification of this is possibly open 

 to doubt) picicorriis, Hope. This leaves 56 which probably 

 appertain to Chalcopterus so far as I have been able to ascertain. 

 Of these 56 there are 10 which I feel confident that J have not 

 seen, viz., convexiusculus, Macl., cuj^ido, Pasc, cupricollis, Hope, 

 ellijysoides, Pasc, indigaceus, Pasc, minutus, Pasc, pusillus, 

 Pasc, semissus, Pasc, sidci'peiuiis, Hope, tarsalis, Pasc. Of the 

 following 7 I have examples of whose identification I feel con- 

 siderable doubt ; but I am confident that if my identification of 

 them is not correct I have not seen the species, viz., cuj)reus, FaVi., 

 grandis, Macl, maurrthts, Pasc, obhosus, Pasc, obsoletus, Macl., 

 vinosus, Pasc, semiticus, Pasc. Of the remaining 38 species 9 

 are, I have little doubt, .synonyms, viz., coelestis, Pasc, and IcevicoUis,' 

 Blessig = cyanijjennis, Hope ; venereus, Gmel. = cupreus, Fab. ; 

 purpureus, Germ. = anthracinus, Hope ; rugosus, Germ. = 

 sulcip)ennis, Hope; Howitti, Pasc, and affinis, Blessig = cupripennis, 

 Hope ; rufipes, Rlacl. = nigritarsis, Pasc ; triangularis, Haag- 

 Rut. = semiticus, Pasc The following six I am obliged to 

 disregard as being described in such fashion that it is impossible 

 to form any opinion concerning them, viz., resplendens, Boisd., 

 puncticollis, Hope, smaragdulus, Fab., tristis. Fab., velutinus, 

 Macl., viridicoUis, Macl. The following two identifications may 

 be regarded as jJrobable, viz., hicolor, Fab., and columhinus, Boisd., 

 with GU2)rip>ennis, Hope, and cyanipennis, Hope, in which case 

 Hope's names will become synonyms. Thus there are 22 names 

 that I regard as representing good species known to me and 

 belonging to Chalcop)terus, 17 (among which are probably a few 

 that do not belong to Chalcop)teras) that 1 have identified doubt- 

 fully or not at all, but all of which are likely to be good species, 

 and 17 that are either mere names of practically undescribed 

 insects or else, probably, synonyms. 



It will be Avell to remark that in identifying Hope's, Germar's, 

 and Blessig's species, I have possessed the advantage of a personal
