sharp dentiform projection externally : posterior trochanters broad, 

 short, widely rounded at apex : tarsi iiarrow, without spongiose 

 tissue on underside of anterior ones : posterior elongate ; joints 

 1-4 successively shorter — first, long, about as long as two suc- 

 ceeding ones together, last narrowed to apex. 



Length, Lt-S ; breadth, 5-5 mm. 



Female differing from male in its ratlier ligliter form ; smaller 

 head ; prothorax proportionately narrower than elytra (4-25 x 4-25 

 mm.) ; elyti-a more convex and less widely rounded behind 

 (8-75 X 5'25 mm.) ; last joint of the palpi narrower. 



Length, 14'-5 ; breadth, 5-25 mm. 



Habitat. — Barrow Range, Central Australia. Two specimens, 

 male and female. 



This species is allied to P. australis, SI., and J\ atroiiilens, SI., 

 from both of which species it may readily be distinguished by the 

 slightly projecting anterior angles of the prothorax, by both pro- 

 tfiorax and elytra being less rounded at the middle of tlieir 

 length, and by the decidedly impressed suture of the elytra. 

 Tliese three species all have the posterior coxse tripunctate.* 

 P. carbonaria, Casteln., a black species from West Australia, 

 very little larger than the present, I have never seen ; it ditfers 

 by description in having the labrum rounded, t 



Parroa apiealis, yxc. non. 

 Form broad, convex ; upper surface smooth, excepting apex of 

 elytra. Black, shining. Head la-rge (.5-25 x 5-25 mm.), smooth, 

 wide, but not swollen behind eyes ; front with two well-marked 

 long parallel impressions extending to margin of clypeus near its 

 anterior angles ; clypeal suture fine, bent forward sharply on 

 each side, a small puncture on each side at the angles made by 

 the lateral bend ; clypeus with anterior margin very lightly con- 

 cave, a foveiform setigerous puncture on each side ; eyes round, 

 convex, not prominent or inclosed behind. Mandibles long,

f I have lately obtained specimens (both male and female) of Parroa 

 aimtraln, SL, as coming from South Australia, but without exact locality. 

 I am therefore able to report that the male is comparatively broader than 

 the female, the elytra having a shorter and more convex appearance. The 

 maxillary palpi have the penultimate joint very short and triangular with 

 a seta projecting forward on the internal side, the last joint oblong, thick, 

 truncate, a little narrowed to apex ; the labial palpi have the penultimate 

 joint bisetose in front, and without setfe at apex, the last joint thick, 

 arcuate externally, narrowed to apex, truncate. The legs are light, the 

 anterior femora slightly dilatate in micldle, the anterior tarsi not dilatate or 

 with brushes of spongiose tissue on underside ; the posterior tarsi narrow ; 

 joints elongate, first long, hardly as long as two succeeding ones together, 

 last elongate, narrowed to apex. Length, 1.5 '5 ; breadth, 5 '5 mm. Speci- 

 mens before me vary in length from 14'5 mm. to 17 mm.
