the maJe of this insect — of which I have net seen the female — 

 very distinct. The great width of its prosternal sulci and its 

 serrate antennae associate it with T. Macleayi, Blackb., which 

 di£fers from it inter alia by the club of its antennse in the male 

 being — not merely serrate but — strongly pectinate, and eight- 

 jointed.

 T. exsul, sp. nov. Late ovale ; sat nitidum ; supra pube subtili 

 fulva depressa vestitum ; nigrum, elytris versus apicem 

 antennis (clava excepta) pedibusque rufo-testaceis ; pro- 

 thorace fortiter transverso, antice angustato, supra sat 

 crebre minus subtiliter nee profunde punctulato, angulis 

 posticis retrorsum leviter directis haud acutis ; elytris crebre 

 subforliter punctulatis ; metasterno antice lato, late rotun- 

 dato ; prosterni sulcis profundis, bene determinatis, postice 

 clausis. 

 Feminse antennarum clava 3-articulata. Long., 1 L; lat., ^ 1.

 Although I have not been able to examine the male of this 

 species, I have no hesitation in describing it, inasmuch as its 

 vestiture — fine depressed fulvous pubescence — renders it ex- 

 tremely distinct among the Australian I'rogodermata.

 T. debilius, sp. nov. Sat late ovale ; sat nitidum ; supra pilis 

 brevibus erectis vestitum ; nigrum, palpis tarsis et anten- 

 narum stipite testaceis, harum clava picescenti, elytris 

 postice nonnihil rufescentibus ; antennarum articulis 8° — 10° 

 sat transversis ; prothorace valde transverso, antice angus- 

 tato, supra sat leviter minus crebre punctulato, angulis pos- 

 ticis retrorsum directis sat acutis ; elytris crebre sat fortiter 

 punctulatis ; metasterno antice lato, inter coxas intermedias 

 late rotundato; prosterni sulcis profundis, bene determinatis, 

 postice clausis. 

 Maris antennarum clava 5-articulata, articulis 8° — 10° sat 



transversis nee quam longioribus duplo latioribus. 



Feminae antennarum clava 5 articulata quam maris multo 



breviori (prsesertim articulo ultimo), articulis 8° — 10° quam. 



longioribus fere duplo latioribus. Lorg., If 1.; lat , i 1. 



The club of the antennae in the male is very evidently longer 



than all the other joints together^ in the female a little shorter 



than the other joints together. Among the species resembling 



this one in the form of their prosternal sulci and in their anten- 



nal club being black or nearly so in contrast with the testaceous 



stipes (which seems to be a perfectly reliable specific character) it 



is distinguished by the joints 8 — 10 of its antennae being not so
