smaller. The female differs much from P. nitidus in the shape 

 of the head and thorax. It is not improbable that the present 

 species is Lophocheilus distinctus Guer., but the description of that 

 species is too poor for recognition. 



The male is the type.

PSAMMOTHYNNUS KERSHAWI, Sp.n. 



(J. Niger ; clypeo, mandibulis, orbitis oculorum, margine 

 anteriore pronoti angustissime, tegulisque basi flavis; segmentis 

 abdominalibus secundo, tertio quartoque, primo dimidio apicali 

 quintoque lateribus, femoribus, tibiis tarsisque rufo-testaceis ; 

 mesopleuris macula magna flava antice; alis hyalinis, venis f uscis. 

 Var. Pronoto omnino nigro. Long. 12mm. 



<J. Clypeus large, convex, broadly truncate at the apex ; the 

 interantennal prominence well denned, and narrowly rounded at 

 the apex. Antennae shorter than the thorax and median seg- 

 ment combined, the apical joints feebly arcuate beneath. Front 

 rugosely punctured, vertex and thorax finely and rather closely 

 punctured. Median segment rounded, shallowly punctured. 

 Abdomen flattened, long and slender, much narrowed to the 

 base; the segments slightly constricted at the base, shining and 

 very sparsely punctured, clothed with whitish pubescence on the 

 sides. Hypopygium deeply emarginate at the apex, the apical 

 angles produced into spines, a tuft of long hairs at the apex. 

 Second recurrent nervure received at about one-third from the 

 base of the third cubital cell; third abscissa of the radius a little 

 longer than the first and second combined. 



Hab. — King Island, Bass' Straits" (J. A. Kershaw), December. 



This is not quite a typical Psammothynnus, the antennal joints 

 being less strongly arcuate beneath, and the second recurrent 

 nervure being received further from the base of the third cubital 

 cell than in P. depressus Westw. One specimen has the coloured 

 portion of the abdomen fusco-ferruginous instead of rufo 

 testaceous.
