front by a feebly raised carina. No trace of horn in any of the eight specimens 

 seen by me. Thorax very shining, with fine but distinct punctures. The anterior 

 two-thirds occupied by abroad, and in the middle very deep, excavation, from within 

 which on either side near the lateral margin rises a lofty, laterally compressed, 

 bluntly triangular elevation, the apex of which is slightly incurved. The centre of 

 the excavation is occupied by a slender carina running from the base to the anterior 

 margin, which is slightly raised. Anterior angles of thorax sharp and rather pro- 

 duced. Elytra distinctly punctate-striate, interstices broad and flat, minutely 

 punctured. Pygidium dark green, sparsely punctate. Under-side blackish-green. 

 Metasternum smooth, but with a few coarse punctures at its lateral margins ; a 

 slight central sulcus ; anterior spine very long. The prosternal ridge terminates in 

 front in a minute sharply pointed spine. Femora blackish-green ; tibise black, the 

 anterior pair bluntly tridentate. Antennae piceous, with the basal joint very long. 

 Pubescence dark piceous, almost black. Long., 16 mm, 



Pteroderus, Beiche, in lift. 



The specimen here described was kindly lent me by Dr. Sharp. 

 It is now in the collection of Mons. E/. Oberthiir. The label on this 

 example states that it was found at Monte Video, but the majority of 

 those that have come under my notice have been from much further 

 north, Espiritu Santo and ~R\o Janeiro.
