744 AUSTRALIAN AND TASMANIAN PSKLAPHID^, 



middle. Metasternum widely and sliallowly concave. Front 

 trochanters rather acutely dentate; front tibiae regularly increas- 

 ing in width, but near apex suddenly and strongly emarginate to 

 apex itself, the emargiuations rather densely clothed, middle 

 tibiae rather acutely mucronate at apex, the hind pair less notice- 

 ably so. Length 1^-lf mm. 



^. Differs in having somewhat shorter antennse, with none of 

 the joints produced inwards, the tenth much smaller, the eleventh 

 simple at its inner base and fully twice the length of the tenth, 

 the undersurface of abdomen convex, metasternum less widely 

 and more shallowly concave, and legs unarmed. 



JIab. — Tasmania : Hobart, Mount Wellington, New Norfolk. 



The body is somewhat as in B. 5-foveata, but the antennse are 

 stouter and shorter, tenth joint different, abdomen non-carinate, 

 etc. On some specimens the elytra are of a uniform shade of 

 colour, but on otliers the suture, sides and apex are slightly darker 

 than elsewhere. The medio-frontal cephalic fovea is larger than 

 the interocular ones (with which, from some directions, it appears 

 to be vaguely connected), closed in front and not circular. The 

 eleventh joint of the male on the undersurface has a slight depres- 

 sion in which tlie produced inner apex of the tenth can be fitted. 

 From some directions the eighth and ninth are seen to be pro- 

 duced inwards. The epipleural furrow is short; it commences 

 and is fairly deep at about the basal fifth, but rapidly shallows 

 and terminates about the middle; in the female it is less distinct 

 than in the male. 



Abundant in moss, and a few specimens taken from tussocks, 

 and rotting leaves. 



Rybaxis pallida, n.sp. 



(^. Of a rather pale castaneous, appendages still paler. With 

 short, pale, and, for the genus, fairly dense pubescence. 



Head comparatively wide, with(for tlie genus) a rather small 

 fovea close to each eye, and with a rather shallow subfrontal 

 impression. Antennje comparatively thin, second joint fairly 

 large, third to sixth of about even size, seventh and eighth some- 

 what smaller, ninth slightly larger, and tenth slightly larger still,
