Aiistrdlian and TasmaniaM Coleoptcra. 177 



til)iae are about three times as long as wide, instead of only 

 twice as long as wide, or even not nuich longer than wide (as 

 in most species of the genus). The disc of the prothorax, as 

 well as of the elyt-ra, is clothed with brownish suberect setae. 



Artliropferii^ Wesfiroodl, Macl. 



Two specimens from Gayndah were received as co-types of 

 this species. Tliey have the sides of the elytra at the base 

 with clothing as on the sides of the prothorax, but scattered 

 all over the elytra are some exceedingly fine setae, that readily 

 escape observation, even from the sides ; esjjecially if, as is 

 usually the case, they are a trifle greasy or dusty. 



Arfhrn//ffrits aii(/ulatust, Macl. 



A co-type of this species has elytral clothing as described 

 for the above species, to which it is remarkably close. 



Mr. Aug. Simson has taken several specimens of the species 

 in ants' nests at Bowen. 



Arthropterus suhrylindricus, Macl. 



Two specimens in cop. were taken under a stone at Quean- 

 beyan. close to a nest of ants ; and another pair under a 

 stone at Millthorpe, also not far from a nest of ants. 



Artliroptcrus ueyhctus, n.sp. 



Dark reddish-castaneous, margins suture and appendages- 

 (tarsi excepted) somewhat paler ; h^ad black. With very short 

 and very sparse setae, except on sides and pygidium, where 

 they are fairly numerous ; sides also with a few short hairs. 



Head with dense irregular punctures ; sides subtuberculate 



behind eyes. Antennae with more numerous punctures along 



sides, and paler and less jjolished than along middle, third to 



tenth joints each about five or six times as wide as long, 



eleventh almost as long as three preceding combined. Pro- 



tliorar about two-thirds as long as greatest width, which is 



near a})ex, sides thence strongly rotmded to apex itself, and 



feeblv diminishing to l)ase ; mara-ins slighth' upturned, more
