(especially its extremely narrow, — almost linear, — non-prominent 

 labrum) separate it widely from Heteronyx. In my tabulation of 

 the Australian Sericoid genera (Tr. R.S., S.A., 1898, pp. 32-4) 

 it must take its place beside Heteronyx, — which is perhaps its 

 most natural position. To include it in the tabulation, the 

 following must be substituted for line 25 on page 34 : — 

 FF. Form notably more convex. 



G. Labrum largely developed and prominent ... Heteronyx. 



GG. Labrum extremely narrow and not prominent ... Anacheirotus. 



A. inornatus, sp. nov. Totus pallide testaceus ; supra sparsim 

 breviter pubescens, lateribus longe ciliatis ; sat nitidus ; 

 clypeo crebre subtiliter, capite postice fortius minus crebre, 

 prothorace fortiter sparsim, elytris quain prothorax magis 

 crebre paullo minus fortiter, pygidio sparsim minus fortiter, 

 punctulatis ; clypei lateribus ante oculos fortiter angulatis ; 

 pronoto transverso, antice paruni angustato, lateribus 

 leviter rotundatis, angulis anticis leviter acutis posticis 

 rotundatis. Long., 2 4 1.; lat., li 1. 



The clypeal canthus cuts into the eye to a little in front of its 

 middle, and its lateral margin is strongly angular behind, the 

 apex of the angle projecting a trifle beyond the outline of the 

 eye.

AXOPLOGNATHUS. 



A. concinnus, sp. nov. Mas? Sat brevis ; minus convexus ; 

 nitidissimus ; supra glaber, corpore subtus pygidioque 

 sparsissime albido-pilosis ; supra brunneo-castaneus plus 

 minusve viridi-micans, corpore subtus obscure viridi vel 

 cyaneo plus minusve violaceo-micanti, metasterno medio 

 (exemplorum 2 visorum) splendide aureo, antennis palpis 

 pedibusque castaneis ; supra sparsim subtiliter punctulatus, 

 elytris puncturis paullo majoribus lineatim leviter impressis, 

 pygidio ad latera paullo magis perspicue punctulato ; clypeo 

 antice sat fortiter elevato-reflexo, rotundato \ antennarum 

 clava quam articuli pra?cedentes 5 conjuncti sublongiori ; 

 prothorace fortiter transverso, antice modice angustato 

 leviter emarginato, postice fortiter bisinuato (lobo mediano 

 baud emarginato), lateribus fere rectis, angulis anticis vix 

 acutis posticis sat abrupte rectis ; elytris ad apicem con- 

 junctim late rotundatis ; mesosterni processu elongato, 

 acuto ; tibiis anticis externe 3-dentatis, dentibus apicalibus 

 2 approximatis inter se, dente 3° (hoc paullo ante tibiam 

 mediam sito) subobsoleto ; unguibus ad apicem acutis haud 

 fissis. Long., 6 J 1.; lat., 3^- 1. 

 This species is the smallest Anoplognathus yet described, being
