234 THE GENERA AND SPECIES OF AMYCTERID^, 



proach to Amycterus proper. The thorax is angled in the middle, 

 but not to the same extent as in the last species. 

 My only specimen is a male. 



3G, — Talaurinus Mitchellii. 



Oblongo-ellipticus niger cinereo-squamosus, rostro fronteque 

 albido-vittatis, thorace tuberculato tuberculis hemisphae- 

 ricis lateraliter remotis, elytris rude punctatis subseriatim 

 irregulariter tuberculatis apice mucronatis, ventre medio 

 cinereo-squamoso. 



Long. 9 lin., lat. 3 lin. 



Hab. Victoria River, Mitchell's Expedition. 



This species is very like T. typicus. It is more thickly 

 clothed with cinereous scales, and has the tubercles more thinly 

 disposed on the sides of the thorax. The elytra also are com- 

 paratively broader than those of typicus. The apex of the last 

 ventral segment is excavated and emarginated in the only spe- 

 cimen I have seen. 



37. — Talaurinus catenulatus, 



Oblongo-ellipticus niger densius cinereo-squamosus, fronte 

 subexcavata, thorace sparsim tuberculato tuberculis obtusis, 

 elytris rude seriatim punctatis interstitiis 1 et 2 catenulatis, 

 3 piano, 4 et 5 crebrius tuberculatis apice minute 

 mucronatis. 

 3Ias : segmento ultimo ventrali medio excavato, ano utrinque 

 penicillato. 



Long. 10 lin., lat. 31 lin. 

 Hab. New Holland. 



The head and rostrum of this species resemble those of T. 

 typicus, excepting that in the last named insect the transverse 

 suture at the base of the rostrum is more distinct. The thorax 

 is thinly covered with obtuse tubei-cles, the medial line being 

 distinct. The elytra are coarsely punctured in rather irregular 

 rows, the first and second interstices ai'c composed of oblong 

 rather glossy tubercles, the third interstice is plain, the others
