238 THE GENERA AND SPECIES OF AMYCTERIDyE, 



45. — Talaurinus Kirbyi. MacLeay. 

 Psalidura Kirbyi, MacL., App. to King's Voy. p. 444. 



" Nigro-fusciTS clypeo-subfurcato utrinque canaliculato, thorace 

 confertim noduloso, elytris lineis elevatis interstitiis crenatis 

 lateribusque punctato-striatis." MacLeay. 



Long. 8 lin., lat. 3 lin. 

 Hab. New Holland. 



This insect appears to be quite distinct from the A. Kirbiji 

 of Boisduval and Schonherr. It seems unaccountable that no 

 notice should have been taken by either of these authors of the 

 species described by Mr. MacLeay under that name. The rostrum 

 is broad, and has the two internal ridges nearly parallel along its 

 whole length. The thorax is but slightly ampliated at the sides, 

 is closely covered with small tubercles, and has an irregular 

 narrow transverse impression near the anterior margin. The 

 elytra are ribbed, with the intervals consisting of two rows of 

 rugose punctures presenting a rather reticulate appearance. The 

 sides are strongly rugose, and the apex slightly mucronate. There 

 can be no doubt of the identity of this insect, as the original 

 specimen named by Mr, MacLeay is in my possession. 



46. — Talaurinus costatus. Boisd. 



Amycterus costatus, Boisd., Voy de I'Astrol II., p. 384. 



" Ater oblongus thorace granifero, elytris tricostatis interstitiis 



reticulatis costis lajvibus." Boisduval. 

 Long. 10 lin., lat. 3| lin. 

 Hab. New South Wales. 



This species is very like the last. It differs from it in being 

 larger, and of a naore intense black ; in having the head slightly 

 excavated in front ; in having the ridges of the rostrum oblique ; 

 in having no transverse impression on the thorax ; and in having 

 the elytra more strongly marked between the "costse," with their 

 apex more distinctly mucronate.
