iter's species beyond saying that the insect which I take to be it 

 is veiy distinct from all the following, which appear to be new : — 



T. Eyrense, sp. nov. Ovale (feminis subparallelis) ; obscure 

 nigro- et fulvo-hirtum ; nigrum, antennarum articulis 2-6 

 tibiis tarsis et elytrorum lateribus apiceque plus minus rufes- 

 centibus ; obscure sat crebre punctulatum ; sulcis anten- 

 nariis profundis bene determinatis, triangularibus, postice 

 clausis. 

 Mas. Antennarum clava 5-articulata, quam articuli 1-6 

 conjuncti multo longiori ; horum articulis 2-5 minutis ?equali- 

 bus, 6° quam S*"^ paullo longiori et sat latiori ; clava cylin- 

 drica, hujus articulo 1° quam sequentes multo breviori, 2°-4:° 

 sat sequalibus, 5° acuminato quam 3"' 4"^ que conjuncti vix 

 breviori ; antennis quam prothorax vix brevioribus. 

 Femina. Antennis paullo brevioribus ; clava quam stipes vix 

 longiori, illius articulo ultimo quam prascedens paullo longiori. 

 Long., If— If 1. ; lat., f 1.— 1 1. 

 It should be noted that the sixth joint of the antenna3 is so in- 

 termediate in width between the fifth and seventh that it might 

 almost as well be classed with the club (making it six-jointed) as 

 with the stipes. I have reckoned it as belonging to the latter 

 because its length is perhaps more harmonious with that associa- 

 tion. There is not any very great difference between the antennee 

 of the male and those of the female ; in the latter, however, the 

 club being evidently shorter than in the former, and especially 

 the last joint being shorter as compared with the preceding joints. 

 The pilosity of the upper surface is fairly dense and consists of 

 black and greyish or fulvous hairs intermingled. 



South Australia ; basin of Lake Eyre. 

 T. alpicola, sp. nov. Ovale ; obscure nigro- et griseo-hirtum ; 

 nigrum, antennarum articulis 2-6 (vel 3-6) tarsis et elytrorum 

 apice rufis; obscure minus crebre punctulatum; sulcis anten- 

 nariis profundis bene determinatis, triangularibus, postice 

 clausis. 

 Femina (?). Antennarum clava 5-articulata, quam articuli 1-6 

 conjuncti haud longiori, articulis 3-6 parvis ajqualibus, clava 

 ovali, hujus articulis 1-3 ex ordine latioribus, 4° 3° a^quali, 5^ 

 quam 4"* paullo longiori sat angustiori ; antennis quam 

 prothorax sat brevioribus. Long., If 1. ; lat., f 1. 

 Although I think the specimens before me are females, I have 

 no hesitation in describing this sj^ecies, since the differences be- 

 tween the male and female are but slight in all the species known 

 to me that are closely allied to the present one, consisting chiefly 

 in the females being larger than the males, and having the apical 

 joint of the antennae — or the whole club of the antennas — some-
