560 REVISION OF THE AMYCTERIDiE,

 the forceps; forceps moderate in length, slightly curved, laminae

Hah. — Queensland(Macleay Museum). 



The very broad, deeply foveate form of this insect is quite 

 distinctive. From P. forficulata, besides shape and elytral 

 sculpture, the more widely separated fascicles will distinguish it. 

 It is closely allied to P. flavosetosa, but the elytral sculpture is 

 very different; while P. flavosetosa is a much larger, robust 

 insect. P. Frenchi differs in the elytral sculpture. The unique 

 type in the Macleay Museum is the only specimen of the male I 

 have seen; a female in the same Collection bears a label ** Swan 

 River," but this is evidently erroneous. 



PsALiDURA Frenchi, n.sp. 



(J. Elongate, convex. Prothorax finely granulate; elytra 

 striate, interstices finely granulate; fascicles moderately far apart; 

 forceps long, laminae linear. Black, opaque, densely clothed with 

 minute brown scales, interspersed with lighter-coloured patches 

 along the sides, scales on underneath parts yellowish in colour; 

 granules not clothed, each bearing a stout, decumbent, dark 

 brown seta; fascicles black. 



Head convex, to a great extent covered by prothorax, densely 

 clothed and setigero-punctate. Rostrum short, thick, deeply 

 emarginate in front; basal sulci short but well marked, median 

 area almost linear. Mandibles with the hirsute portion strongly 

 lipped. Prothorax(6 x 6 mm.) evenly rounded on sides; apical 

 lobe moderately produced, base truncate; collar-impression defin- 

 itely marked, median line faint at base and apex; disc feebly 

 convex, finely setigero-granulate, the granules finer and closer 

 together towards the centre. Elytra(l4-5 x 9 mm.) evenly rounded 

 on sides; apex abruptly rounded, flanged and strongly mucronate; 

 base truncate, humeral angles marked by a small nodule, not very 

 prominent. Disc foveo-striate, fovese small, shallow, somewhat 

 irregular, each separated by a setigerous granule; interstices not 

 very prominent, finely and rather irregularly granulate, sutural in
