208 THE GENERA AND SPECIES OF AMYCTERID.E, 



Long. 11 lin., lat. 4 lin. 

 Hab. Lambing Flat. 



The head in this species is but slightly hooded by the thorax, 

 and the impressions on the rostrum are not very deep. The 

 thorax is rather depressed in the middle, bulges out a good deal 

 at the sides, and is closely covered with small setigerous tubercles. 

 The elytra are mucronate, and are covered with rows of large 

 shallow punctures, separated by rows of minute shining setigerous 

 tubercles, the alternate rows being double ; there is also a 

 minute setigerous tubercle between each puncture. The whole 

 insect is covered with short cinereous scales and nearly black 

 set^. The anal appendage of the male is large, strong, and 

 clothed with yellow hair, while the anal ventral segment of the 

 female is glossy in the middle and clothed with yellow " setas " 

 behind, and at the sides. 



This species seems to be abundant in the interior of New 

 South Wales. I have specimens from Wellington Valley and 

 the Lower Murrumbidgee, which differ from the above description 

 in having the " seta5 " of a more intense black, in having the 

 medial line of the thorax perceptible, and in having the facial 

 impressions more marked. They will probably be found to 

 constitute another species.

" Oblonga atra in cavitatibus parce cinerea, capite canaliculate,

 costatis costis interstitiisque crenulatis." Boisduval. 



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



Hab. Van Diemen's Land. 



The sculpture of the elytra in this insect is not unlike that of 

 the last described species, the thorax, however, is more depressed 

 in the middle, and more bulged out at the sides, while the 

 impressions on the rostrum are in the shape of a horse's hoof. 

 The anal forceps of the male is short nnd strong.
