ampliated towards the apex, finely and densely granulate-punctate 

 and pubescent with three rather indistinct costse on each elytron.

Hah. — Russell Kiver. 



87. Pal^strida flabellicornis. 



Black, opaque, densely granulose-punctate, the back of the head, 

 the thorax, the base of the elytra and the sterna, orange with a 

 plush-like lustre and texture. The head resembles that of P. 

 concolor, but the antennae are more elongate, reaching to the apical 

 third of the elytra, and from the outer apex of each joint from the 

 third to the tenth, a branch extends of greater length than the 

 joint itself. The thorax also resembles the last species, but the 

 width is slightly moi'e.than the length. The scutellum is orange. 

 The elytra are broader than the thorax, and five times the length 

 and ampliated behind with three rather indistinct costse on each 

 elytron. The bases of the thighs are reddish yellow. 



Length, 5 lines. 



Hab. — Russell River. 



88. Pal^strida nigripennis. 



Entirely black, excepting the thorax, prosternum and labrum. 

 In sculpture it resembles exactly the two foregoing species, the 

 antennae however are not branched as in P. Jiahellicornis, and are 

 more acutely serrated than in P. concolor. The thorax also in 

 this species is not broader than long. The scutellum is black. 



Length, 5 lines. 



Hah. — Mossman River, 



These three species clearly belong to the same genus, but whether 

 they actually belong to the genus Palcestrida vixdij be doubtful.
