Australian and Tasmanian Coleoptera. 157 



?• Differs in the anteniiJK* lacing shorter, with the ninth joint 

 no long-er than the eighth, the t-enth stouter and lontrer than 

 the ninth (but uiuch shorter than in the male), and the eleventh 

 somewhat shorter than in the male, but as long- as the four 

 preceding joints combined, the abdomen also is nonfoveate. 



Hah. — W. Australia : Swan and Vasse Rivers (A. M. Lea). 



Close to the description of jxirvns (the abdominal impres- 

 sion of which is not mentioned), but that species is said to 

 have the prothorax with the sides " not dilated in the middle, 

 so tliat it is not narrower at the base than in the middle.'' In 

 the present species it is quite certainly narrower at the base 

 than at the middle, and the apex is nmch narrower than the 

 middle. Tlie third abdominal segment of the male with a quite 

 round fovea distinguished from the description of inaequalis, in 

 which it is said to be suboblong. Tbe antennae are slightly 

 longer than in iiinrosus (or at least fully as long) instead of 

 slightly shorter as in the description of pafruelis. (Of the latter 

 species the abdominal impression is not mentioned.) 



Three only of the numerous specimens before me are noted 

 as from ants' nests, two of these (sexes) being from a nest of 

 Creinatogaster loeviceps. 



Sdiiiati inon ijhihuliftr. Schfs. 



Messrs. Goudie and Davey have taken numerous specimens 

 of a species from nests of Iridomyrmex nitidus, which cer- 

 tainly belongs to Soinati pioii, and probably to glohiilifer. The 

 genus' is readily identified amongst the Australian Pselaphidae 

 \)\ its antennae and abdomen. Tlie former are eleven jointed 

 with a large globular terminal joint," whilst the abdomen has 

 a very decided median longitudinal impression on its upper 

 surface. 



The specimens before me have the head rather longer than 

 in the figure, the abdomen less inflated in the female, and still 

 less inflated in the male. These specimens range from 2^ to 

 ■i mm. in length, the indicator at the side of the figure is 3 mm. 

 in length. The pubescence on some specimens is rather looser 

 than on others, but this is probably due to treatment. 



1 Raffra.'i 's beautiful fliiure renders the genus easy of identification. Reference to this 

 fi<,'ure (Uevne d* Eiitomologie, 1S90, pi. iii., fij^. 31) is omitted from his recent g-eneric- 

 revision of tlie family.
