and Species of Prionidie. 41 1 



puiictato, lateribus dentato-serratis ; elytris crcbre punctulatis, 

 piceis, nitidis, leviter quadricostulatis. Long. 34 lin. 



Hah. Dorey. 



The above diagnoses are made from specimens forming a part 

 of the rich collection made by Mr. Wallace in the Malayan 

 archipelago, and will be treated in detail in my ^ Longicornia 

 Malayana.' In the interval they will be redescribed by Prof. 

 Lacordaire in the forthcoming volume of the 'Genera/ and 

 they are now in his hands for that purpose. I am already in 

 possession of his views regarding the affinities of these genera ; 

 and although they are not in all cases in accordance with what is 

 here given, I have thought it better to let what I had previously 

 written stand without any alteration. 



I have taken this opportunity to describe some new species of 

 the family from other localities. One is an entirely new genus, 

 from the extreme north of Austraha ; and another is a second 

 and very distinct species of Hoplideres, from Madagascar*. 



Prionus Gerrardu 



P. capite prothoraceque nigrescentibus, hoc dentibus duobus latis 

 utrinque instructo ; antennis 1 1-articulatis, articulis a quinto ad 

 decimum apice unilateraliter productis. 



Hab. Madagascar. 



Head and prothorax brownish black, roughly punctured; 

 eyes large and nearly approximate above ; each side of the pro- 

 thorax with two broad teeth, the posterior angle not produced, 

 the disk with three large flat tubercles, punctures coarse and 

 crowded ; scutellum coarsely punctured ; elytra elongate, parallel, 

 light brown, thickly punctured, the intervals very slightly wrin- 

 kled, each elytron with four raised lines, which by their union 

 present a small reticulate area near the apex, the latter completely 

 rounded ; body beneath glossy reddish brown ; legs rather feeble, 

 clothed with short stiffish hairs; antennse 11 -jointed, the fifth 

 to the tenth joints, inclusive, prolonged on one side at their 

 apices, the last elongate-ovate. Length 18 lines. 



A somewhat long and depressed species, with feeble legs ( J" ), 

 not suggestive of any near ally. I have named it after the late 

 Mr. W. S. Gerrard, who fell a victim to the climate while col- 

 lecting in Madagascar. 



* The names of two of the genera of Prion idtc are preoccupied, viz. 

 Chiasmus and Hephialtes, J. Thorns., the former previously used in the 

 Ilcniiptcra by M. Mnlsant, and the hitter (more correctly Ephialies) by 

 Keyserling and Blasius for a genus of birds. Chiasmus I propose to change 

 to Chiasmetes ; Ephialtes is unknown to me. Cacosccles, Newm., will, I 

 fear, be regarded as too near to Cacoscelis, Chev., which has the priority.
