slightly declivous 



obsolete impression ; median line finely but distinctly impressed, 

 crossed along its whole length by very fine striohe ; sides covered 

 with minute transverse strioloe ; anterior margin very lightly 

 sinuate between lateral borders ; base truncate, lightly bordered 

 on each side near basal angles ; anterior angles rather strongly 

 advanced, narrowly obtuse, tlieir inner margin almost straight ; 

 basal angles rather acute, projecting a little Ixickwards and 

 downwards; lateral border rather wide, with thick reflexed 

 edge, widening in front from a little behind anterior marginal 

 puncture, bent downward before the base, a little narro-^ver after 

 the sinuosity thus caused. Elytra ovate (12 x 8-5 mm.), widest 

 rather behind the middle, convex, declivous to peduncle ; posterior 

 part declivous, and rugose towards apex ; sides subparallel in 

 middle, lightly rounded to peduncle, broadly rounded at apex ; 

 suture fine, very narrowly impressed ; border narrow on sides, 

 ^\ ider behind ; two fine punctures on margin at shoulder, none 

 along sides, a few near edge of posterior-third, becoming lost in 

 the apical rugosity. Presternum smooth, sloping gently to 

 anterior margin ; base emarginate ; episterna very finely trans- 

 versely striolate under a lens. Ventral segments smooth, except- 

 ing for a few scattered scratches ; segments .3-6 lightly impressed 

 on sides, tliese impressions very shallow and wide, more distinct 

 on two apical segments. Legs light : femora excavate below only 

 near apex ; anterior rather wider, a little flattened ; posterior 

 long, not dilatate in middle : posterior trochanters short, obtuse 

 at apex : posterior tarsi narrow ; joints elongate, first long (about 

 as long as two succeeding ones) last long, cylindi-ic, narro\s-ed to 

 base.

Habitat. — Australia (exact place of capture uncertain). In 

 the collection of Rev. T. Blackburn. 



This species seems an isolated one by its facies, and the form of 

 the basal angles of the prothorax, before which the lateral border 

 slopes sharply downwards, causing tJiem to become acute. The 

 elytra are much broader behind than in any other sp)ecies I have 

 seen, and far more strongly rugose towards the apex ; this 

 rugosity extends over most of the posterior declivity. The 

 emargination of the mentum is quite edentate and even rounded 

 behind. Only the labial palpi are present in the specimen before 

 uie ; they are more slender than in any other Farroa I have 

 .seen ; the two last joints are of about equal lengtli, tlie last is
