scarcely-described A. nigrolineata of Boisduval, and that the 

 latter name must stand. 



(2) A. (SericesthisJ nigroUn eat a, 'Boisd. This is a common 

 species and seems to be widely distributed, as I have speci- 

 mens that seem to be specifically identical from various locali- 

 ties in Tasmania, Victoria, and New South Wales, I can 

 find no well-defined sexual differences among them; some, 

 however (which I take to be males) are of subparallel elongate 

 form with the ventral segments much flattened, while others 

 are somewhat strongly ovate in form, with ventral segments 

 more convex. 



A. hirticeps, sp. nov. Ovatus vel sat parallelus ; convexus; 

 minus nitidus; subglaber, sed capite antice setis elonga- 

 tis erectis vestito ; antennis 9-articulatis, flabello perbrevi > 

 clypeo confertim, fronte sat crebre, subfortiter punc- 

 tulatis; prothorace quam longiori vix fere duplo latiori, 

 antice sat angustato, supra minus crebre parum subtiliter 

 nee profunde punctulato, vix perspicue canaliculate, 

 lateribus parum arcuatis, angulis anticis acutis posticis 

 acute rectis, basi marginata utrinque parum sinuata; 

 scutello punctulato ; elytris geminato-striatis, fortiter fere 

 subrugulose punctulatis; pygidio sat crebre minus for- 

 titer punctulato ; tibiis anticis extus tridentatis ; tarsis 

 posticis modicis, articulo basali quam 2us manifeste bre- 

 viori; coxis posticis quam metasternum multo breviori- 

 bus; segmento ventrali apicali postice hand vel vix 

 emarginato. Long., 4f-5J 1. ; lat., 2-2J 1. 

 This is the only Anodontonyx known to me with antennae 

 of 9 joints. Its resemblance is to A. nigrolineata, Boisd., 

 from which it differs, independently of its antennae, by, inter 

 alia, its very evidently less rugulose elytra. I do not find any 

 definite sexual differences among the four specimens before 

 me.
