entromus (gen. nov. Anthr ibid arum). 

 Caput transversum ; rostrum planum depressum, quam latius 

 sublongius, antice emarginatum, ad basin quam caput haud 

 angustius, scrobibus obtectis foveiformibus sed oblique 

 retrorsum (ut sulci male definiti) productis ; antennae 

 graciles, prothoracem medium paullo superantes, articulis 

 basalibus 2 paullo incrassatis (2° quam l us multo longiori), 

 3° 2° longitudine sequali, 3° — 8° gradatim brevioribus, 9° — 

 11° clavam oblongam formantibus, 9° obconico vix trans- 

 verso, 10° brevi sat trans verso, 11° leviter transversim 

 obovato ; oculi parvi integri sat subtiliter granulati ; pro- 

 thorax vix transversus, vix insequalis (basin versus trans- 

 versim rugatus), sat convexus, antice minus fortiter 

 angustatus, carina antebasali male definita cum rugis 

 transversis adjacentibus subconfusa, in prothoracis lateribus 

 vix perspicue producta ; scutellum sat parvum ; elytra lata 

 depressa, inaequalia, leviter striata, striis punctulatis; coxse- 

 anticse appoximatae inter se ; pedes modici, inter se sat 

 gequales • tarsi breves, articulo basali quam 2 US parum 

 longiori, 3° in 2° inserto ; unguiculi subtus dente armati ; 

 metasternum modicum ; pygidium (exempli typici) elytris 

 tectum ; corpus pubescens. 

 This genus is difficult to place in Lacordaire's scheme of classi- 

 fication, although it seems to me unnatural to place it far from 

 Tropideres. But according to Lacordaire the fact of its rostral 

 scrobes being certainly not simply t'oveiform would remove it 

 from the " groupe " " Tropiderides." These are almost exactly 

 as in Ecelonerus in outline, but differ in commencing in a fovei- 

 form excavation, the wall of which is interrupted at its postero- 

 interior portion from which a shallow somewhat ill-defined sulcus 

 emerges and simulates the deep strongly defined sulcus of 

 Ecelonerus. The short wide depressed form of the type of this 

 genus removes it, however, according to M. Lacordaire, from the 

 Ecelonerides. The structure of the basal part of the pronotum 

 is unlike that of any other Australian Anthribid known to me, 

 the ante-basal carina appearing merely as one (a little more con- 

 spicuous than the rest) of several fine transverse ridges, and 

 (though very distinct and well-defined near the lateral margins of 

 the pronotum) becoming very faint as it approaches the middle 

 line of the pronotum. From Tropideres itself it differs, inter 

 alia, by the greatly elongated 2nd joint of its antennae. I 

 believe the specimen before me to be a male, but am not sure. 

 Tropideres niusivus, Er., and albuginosus, Er., are probably con- 

 generic with this insect, but the descriptions of those species seem 

 to indicate a different arrangement of the inequalities of the 

 elytra, &c.
