364 INSECTA MADERENSIA. 



cerus and Cyphoscelis, vmquestionably removing it in the opposite direction. Its 

 tendency moreover to have the shoulders porrected, instead of rounded off, would 

 seem stUl further to iadicate an approach towards Ci/jihoscelis ; and it is merely 

 through ignorance of its male characters that I have been induced to place it 

 where I have, — for the sexual distinctions both of Cyphoscelis and Laparocenis 

 are so remarkable, that I think it better to retain it in a confessedly neutral 

 position than to admit it into a well-defined group, only a portion of the elements 

 of which it may perhaps be found afterwards to possess. At the same time, whilst 

 it agrees with these two genera exactly in the peculiarity of its antennae, it is 

 \\'idely separated from them both (even in the female sex) in its longer and un- 

 acuminated rostrum, and in its exceedingly small and jironunent eyes ; and I 

 think it more than probable that its males Avdll display modifications in the struc- 

 tm'e of theu* tibiae equally important. Considering it therefore for the present as 

 an aberrant Atlantis, it will be sufficient to add that it may be at once distin- 

 guished from the remainder of the genus here described, not only by the details of 

 its autenntie above mentioned, but likewise by its somewhat anteriorly-, and 

 posteriorly-pointed outline, by its slightly longer, slenderer, and more deejily 

 sculptured rostrum, by its excessively small and prominent eyes, by its narrow 

 and subcorneal prothorax, by the more porrected humeral angles and somewhat 

 imdulated surface of its bro'svuly-tessellated elytra (which moreover are perfectly 

 free from the elongated, sub erect additional hairs which constitute so remarkable 

 a feature in most of the other species), and by its testaceous legs. My unique 

 specimen I captured, from beneath a stone, on the descent from the Pouso to the 

 level, though elevated plain of the Fateu-as, during the ^prmg of 1848.
