$ , with the thoracic processes pitchy, very acute, the apex re- 

 curved, and tipped with bright orange, strongly channelled be- 

 neath ; the membrane of the elytra is brownish; the abdomen 

 beneath pitchy brown, darkest at the apex, and palest on the 

 outer margins and along the central keel ; ventral spine pale, 

 tipped with brown. Breast brownish, with the sternal keel semi- 

 transparent. Head beneath brownish. 



This species may be at once distinguished from A. umgultaium 

 by the great size of the thoracic processes ; it also wants the large 

 orange spot at the base of the scutellum, which that species pos- 

 sesses. 



Sp. 8. Acanth. (^Sast.) lineatum. 



A. (S.) griseo-testaceum, fusco-punctatum ; thorace linea media

 Head yellow, with a brown line on each side of the median lobe, 

 and a row of brown punctures on each of the lateral lobes. Eyes
