short deep sulcus close to the hind end of the humeral elytral 

 stria (between it and the lateral margin) is an unusual character. 

 The puncturation of the elytra and pronotum is a little stronger 

 and less close than in the species referred to above as S. sinm, 

 Mars., but that of the pygidium does not differ much from that 

 species. The front of the prosternum is spatuliform as in the 

 preceding species and other Hypocacci, but the sides being more 

 strongly declivous this spatuliform shape is less conspicuous.

TERETRIUS. 



T. Doddi, sp. nov. Cylindricus, sat latus ; sat nitidus ; piceus,. 

 latera versus nonnihil rufescens, antennarum clava testacea, 

 tibiis tarsisque plus minusve rufescentibus ; capite subtilius 

 sat crebre punctulato ; prothorace transverso, supra ine- 

 qualiter (ab apice retrorsum gradatim minus subtiliter) 

 punctulato, stria integra impresso, lateribus antice sinuatis ; 

 elytris sat crebre subfortiter (in parte postico-extero minus 

 perspicue) punctulatis, haud striatis ; prosterno subplano, 

 crebre subfortiter punctulato, postice triangulariter emar- 

 ginato, striis bene definitis vix ultra medium continuis ; 

 mesosterno marginato (basi excepta), sat fortiter minus 

 crebre punctulato, antice triangulariter producto ; meta- 

 sterno utrinque stria recta (hac vix ultra medium continua) 

 impresso, sparsim subtilius (ad latera sat fortiter) punc- 

 tulato ; pygidio subtiliter sat crebre punctulato ; tibiis 

 anticis 5 denticulis (e his basali valde minuto), intermediis 6 

 (e his basali valde minuto, 2° — 4° inter se propinquis, 5° 6** 

 que prope apicem positis), posticis 5 (e his basalibus 3^ 

 valde minutis) armatis. Long., 1 1.; lat., ^ 1. (vix). 

 The only previously described Australian Teretrius with 5- 

 denticulate front tibiae is T. australis, Lewis, of which I have an 

 example sent to me by Mr. Lea (it was sent as T. basalts, Lewis, 

 but is clearly not that species, as inter alia it has 5-denticulate 

 front tibiae and the mesosternum obtuse in front). The present 

 species differs from it inter alia by its mesosternum quite sharply 

 triangular in front and its elytra very considerably more strongly 

 punctulate.

TERETRIOSOMA. 



Of this genus two Australian species (melburnius, Mars., and 

 Somerseti, Mars.) have been described. They were attributed to 

 Teretrius by their author. They are readily distinguishable 

 according to their author (though closely allied) by i7iter alia the 

 front tibise of the former having 7 denticles and those of the 

 latter only 5. The former is a common species in Southern
