The remarkable insect on whicli this genus is founded must 

 be somewhat allied to Teratidium macros, Bates, one of the 

 rarest and most interesting of Australian Carabidce. It differs 

 from it, however, in certain respects that render the two incap- 

 able of being associated in the same genus. The general form 

 of this insect — the rounded head, the extremely incrassated 

 apex of all the palpi, the bisinuate labrum prominent in the 

 middle, the prominent eyes encased behind in broad orbits, and 

 the projecting tooth at the shoulders of the elytra — are strongly 

 suggestive of Teratidium, but the bidentate anterior tibiae, the 

 head scarcely so wide as the thorax, the well-marked frontal 

 fovese, and the strong external apical spine of the intermediate 

 tibiae, are inconsistent with its finding a place in Mr. Bates' 

 genus. 



E.fortis, sp. nov. Niger ; nitidus; capite (mandibulis inclusis) 

 f ortiter transverso ; antennis prothorace vix longioribus ; 

 prothorace leviter transverso canaliculato, antice subtrun- 

 cato (angulis anticis minus notatis), lateribus in parte 

 anteriore plus quam dimidia leviter emargiuatis, inde 

 f ortiter angustatis, basi leviter rotundata, angulis posticis 

 vix perspicuis, basi apice multo angustiori ; elytris pro- 

 thorace vix angustioribus, subcylindricis, fortiter punc- 

 tato-striatis, striis punctatis apicem marginesque versus 

 obsoletis, humeris externe dentatis ; pedibus validis ; tibiis 

 anticis apice abrupte palmatis, externe fortiter bidentatis ; 

 tibiis intermediis et posticis apice intus fortiter bispinosis. 

 Long., 40 m. ; lat., 11 mm. 



I may add that the elytra are slightly narrowed at the base, 

 and rather deeply emarginate across their front, that there is a 

 row of somewhat elongate impressions in a deep furrow just 

 before the reflexed margin of the elytra, the portion of the 

 elytra on w^hich it is placed being vertical, and that the frontal 

 fovese are very strong behind, commencing in a fovea nearly 

 as far back as the hinder edge of the eye, thence converge 

 strongly to about the level of the front of the eye, whence 

 they diverge again, but become exceedingly faint, and that 

 they are united at their hinder end by a shallow furrow. 



A single specimen of this magnificent insect was taken by 

 Mr. Tepper at Ardrossan, and is in the South Australian 

 Museum.
