Basitropis (at any rate of all the Australian ones, and all other 

 known to me). In respect of other characters not likely to be 

 sexual it differs from B. relicta, inter alia, by its somewhat 

 larger and less cylindric shape, the feeble emargination of the 

 front of its rostrum, the more elongate form of its prothorax 

 which is distinctly (though not much) narrower across its middle 

 than across its base (in relicta that segment is if anything wider 

 across its middle than its base), its evidently narrower rostrum, 

 and the more evident interval between its front coxae. It is to 

 be noted, however, that in neither of the above species are the 

 front coxae separated by a continuous process of the prosternum.

 late Dr. Bovill.

Caput transversum ; rostrum transversum supra sat planum, ad 

 apicem truncatum, ad basin quam caput haud angustius, 

 scrobibus foveiformibus obtectis ; submentum planatum pro- 

 funde triangulariter emarginatum ; antennas graciles, arti- 

 culis basalibus 2 quam sequentes robustioribus (2° breviori), 

 articulis 3° — 8° gradatim brevioribus, 9° — 1 1° clavam dis- 

 tinctam formantibus, hac laxe articulata ; oculi magni, fere 

 integri, sat convexi, minus fortiter granulati ; prothorax 

 fortiter trans versus, transversim fortiter convexus, carina 

 antebasali nulla, carina basali ad latera angulata et antror- 

 sum ad latera media producta ; scutellum parvum ; elytra 

 sat brevia, striata, postice subverticalia ; coxae anticae inter 

 se latissime remotae ; pedes modici, anticis quam ceteri 

 longioribus ; tarsorum anticorum articulus basalis quam 

 ceteri conjuncti parum (posteriorum multo) brevior, 3° in 2° 

 inserto ; unguiculi subtus dente parvo armati ; metasternunL 

 breve ; pygidium manifestum, subquadratum. 



According to M. Lacordaire's classification the small insect 

 for which I found this genus is a member of the " Anthribides 

 vrais," by virtue of the following characters in combination : — 

 Antennae inserted on the sides of the rostrum, carina of pronotum 

 basal, rostrum of subparallel form, body not elongate-cylindric. 

 In that group it is distinguishable by the following characters : — 

 Front coxae very widely separated (more widely than in Phlceobius ), 

 rostrum truncate at its extremity, antennae and legs extremely 

 like those of Arteocerus. The outline of the prothorax and elytra 

 is not unlike that of Ceutorrhynchus. I am uncertain as to the 

 sex of the examples before me. The front margin of the eye 

 itself forms the hind wall of the scrobe.
