722 AUSTRALIAN AND TASMANIAN PSELAPHID.E, 



largely excavated along middle, each side of the excavation near 

 the apex with a small acutely conical tubercle. Ahdoinen widely 

 flattened along middle, apical segment shallowly depressed. Front 

 trochanters acutely dentate; front tibiae gradually dilated from 

 base to beyond the middle, and then suddenly narrowed to apex; 

 hind tibiae strongly and acutely dentate near apex, with the 

 apical half somewhat inflated. Length 1 mm. 



9 Differs in having legs and abdomen simple, and metasternum 

 unarmed and more shallowly impressed along middle. 



Hab. — W. Australia : Swan River, at lights; Vasse River, in 

 flood-debris(A M. Lea). 



The combination of conspicuously pale terminal joint of 

 antennae, curious front and hind tibiae, with the armed meta- 

 sternum of the male, readily distinguish it from all previously 

 described specie.s. 



The interocular impressions are so faint and minute that it is 

 only with great difficulty that they can be seen at all. The 

 metasternal tubercles are very distinct from the sides, and are 

 placed immediately behind the hind coxae. There are 29 females 

 before me, but only six males. 



EUPINBS LITORALIS, n.sp. 



(J. Rather pale castaneous. Clothed with very short, depressed 

 pubescence. 



Head rather more transverse, and with rather larger eyes than 

 usual, interocular impressions very small and faint, frontal ones 

 almost or quite absent. Antennae short, first and second joints 

 moderately large, third to ninth very small, tenth large and 

 moderately transverse, eleventh briefly ovate. Prothorax shorter 

 than usual, widest almost at extreme apex. Elytra conjointly 

 gently arcuate at base, sides moderately dilated posteriorly; 

 dorsal striae entirely absent. Metasternicm very widely and 

 shallowly impressed along middle. Second segment of abdomen 

 with a minute median tubercle. Trochanters unarmed. Length
