EUMENES BAKEWELLI, BoilV. 



This species ranges from 11 to 14 mm. in length, and 

 )• curs in Tasmania as well as in Victoria. 



Dromoeolus dignoscendus, Bonv. 



The description of this species is but little more than a 

 comparison with ferruginipes from Waigiou, the only refer- 

 ence to colour being "la coideur des torses est plus claire.'' 3 

 The length (variable in all the species known to me) was 

 given as 5 mm. There are four specimens before me from 

 Tasmania (the type was from Melbourne), that possibly 

 belong to the species; they are black, antennae (basal joint 

 excepted) obscurely diluted with red, and tarsi and knees 

 rather more conspicuously red (although not brightly so). 

 The pubescence is rather dense and irregularly distributed. 

 The second and fourth joints of antennae are short, subequal, 

 and their combined length about equal to that of the third. 

 'Of the other black Australian species it is distinguished from 

 australasiae by the non-carinated head and fourth joint of 

 antennae much shorter than the third, and from lugubris by 

 the non-carinated head and paler appendages. 



The four Australian species of the genus may be tabu- 

 lated as follows: — 



Derm dull reddish-brown ... ... ... ... interioris 



Derm black. 



Head non-carinated ... ... ... ... dignoscendus (?) 



Head carinated. 



Third and fourth joints of antennae subequal australasiae 

 Third joint much longer than fourth ... lugiibris

Arisus. 

 The species of this genus in general appearance are much 

 like those of Fornax, but are distinct therefrom by short 

 oblique sulci on the metasternum ; to see these clearly, how- 

 ever, it is necessary to force the legs aside. All the species 

 have the head more or less conspicuously tricarinated in front, 

 with the median carina sometimes continuous from base to 

 apex ; on some specimens the median carina is very feeble 

 on the clypeus, so that then the elevations resemble a thin Y. 



Arisus depressus, Bonv. 



A specimen from New South Wales (Tamworth) probably 

 belongs to this species, but it differs from the description in 

 being somewhat smaller (4^ instead of 6 mm.); the carina on 

 its head, from the junction of the oblique ones cm the clypeus, 

 is very conspicuous to the base. The sutural stria on each 

 ■elytron is well denned throughout, and about the base the
