but inter alia is considerably larger, with the basal edging of 

 the pronotum obsolete in the middle of the base, and 

 the antennal flabellum of the male very much shorter and 

 not curved. The present species differs also from *S'. ctnescens, 

 Burm., which, however, is very likely to be identical with 

 sericans, Er.) by the flabellum of the male antennae not being 

 arched, as well as by its considerably larger size.

S. coxalis, sp. nov. Mas. ( ?). Ovata ; convexa ; robusta ; 

 minus nitida; subglabra, sternis femoribusque sparsim 

 pilosis; supra brunneo-rubra nonnihil velutina pruinosa 

 parum iridescens, subtus fere sanguinea, antennis palpis- 

 que pallide testaceis ; antennis 9-articulatis, flabello quam 

 articuli 1-6 conjuncti manifeste breviori ; capite ut S. 

 amhiguce, Blackb. ; prothorace quam longiori duplo lati- 

 ori, antice sat angustato, supra sat crebre sat leviter minus 

 subtiliter punctulato, lateribus leviter arcuatis, margine 

 laterali sat sequaliter elevato, angulis anticis sat acutis 

 posticis (superne visis) acute rectis haud explanatis, basi 

 utrinque sinuata, margine basali in medio obsolete ; scu- 

 tello punctulato ; elytris minus fortiter geminato-striatis, 

 sat fortiter sat crebre punctulatis ; pygidio sat gibbo, con- 

 fertim subgrosse ruguloso ; tibiis anticis extus tridentatis ; 

 tarsis posticis subtus seriatim setulosis, articulo basali 

 quam 2"s sat longiori ; coxis posticis quam metasternum 

 haud brevioribus ; segmento ventrali apicali postice levi- 

 ter emarginato leviter elevato. Long. 7 1. ; lat. 3f 1. 

 The unique specimen described above is unsatisfactorily 

 close to the preceding (S. amhirjua), but differs in a manner 

 that will not allow it to be regarded as a mere variety. Its 

 pygidium (strongly, very closely, and almost coarsely rugulose, 

 and also strongly gibbous) is quite distinct from that of either 

 sex of S. amhigua ; its prothorax, moreover, is very manifestly 

 more strongly transverse, and has sharper hind angles. The 

 velvety appearance of its dorsal surface is very likely to be 

 due to the fresh condition of the specimen when killed. The 

 antero-lateral parts of the metasternum are confluently rugu- 

 lose (in amhigva punctured — by no means confluently). The 

 unique type, in spite of its short antennal flabellum, must be 

 considered a male on account of its gibbous pygidium and 

 quite strongly emarginate apical ventral segment. 



New South Wales ; probably from Mulwala (Mr. Sloane). 



S. aureorufa, Blanch. There is very little in the descrip- 

 tion of this species to indicate any characters that are of spe- 

 cific value \ no mention, for instance, of the structure of the
