XLVll. fig. 7, D.), the third joint being but slightly bilobed. The mentum is 

 very short, and transversely linear, and completely concealing the labium 

 and maxillce, which are densely clothed with hair in front, (Ibid. A.) The 

 species are peculiar to America. 



Still, however, the general, as well as essential, characters of the genus 

 approach so near to those oiSpondylis, (Tab. Supp. xlvii. fig. 8, A B C D E 

 andF,) that we cannot regard the latter otherwise than as the connecting link 

 between Parandra and Prionusy and that the situation given by Latreille, 

 in his last work, to these genera, is the correct one. How are we, how- 

 ever, to regard all these resemblances between this genus as well as some 

 of the preceding and Lucanus ? are they not too striking and important 

 to be considered merely as analogies } and would it be unnatural to re- 

 gard this genus as the osculant one between Lucanus among the Lamel- 

 licornes, and Spondylis and Prionus amongst the Longicornes ? we find 

 the two great groups similar in their herbivorous habits, and also similar 

 in comprizing the giants of the order to which they belong.* 



Hemipeplus, Latr. 



appears to have been first noticed, without any characters, in the Fa- 

 milies J^aturelles, where it was placed as the last genus in the family 

 CucujidcE. In the second edition of the R^gne Animal, Vol. V. p, 53, 

 however, we find the genus removed, and doubtingly placed in the La- 

 griaires. The characters are there detailed, which appear to be very sin- 

 gular. The genus is established, " Sur un insecte trouve en Ecosse, dans 

 " une boutique," forwarded to Latreille by Dr. Leach.
