On the Genus Rhombocephalus. 

 Rhombocephalus, Newport, Trans. liinn. Soc. xix. p. 425 (1845). 



Since this genus was characterized bj Newport it has not 

 been recognized by any author who has worked systematically 

 at the group. This circumstance is easily explained by the 

 fact that the genus was based upon a character which results 

 mainly from the drying of immature examples of Scolopendra. 



In the British Museum there are three types of this genus; 

 these are Rh. viridifrons from France, which proves to be 

 the young of Scolopendra cingulata ; Rh. parvus^ Newport, 

 from Malta, is also a young example of Scolopendra cingu- 

 lata ; Rh. smaragdinus, Butler, from Rodriguez, is the young 

 of Scolopendra suhspinipes^ Leach. Thus, since the type of 

 the genus Rh. viridifrons is a specimen of Sc. cingulata^ 

 Rhomhocephalus must be a synonym of Scolopendra. 



The other typical examples, which I have not seen, will 

 probably prove upon examination to be the young of the 

 species of Scolopendra or Cormocephalus common in the 

 locality from which the types were obtained. 



On Eurylithobius Slateri, Butler. 



Eurylithohiua Slateri, Butler, Phil. Trans. Roy. Soc. clxviii. p. 499 



(1879). 



This genus and species were based upon the exuviated 

 cuticle of a specimen of Scolopendra morsitans. The names 

 must consequently be added to the long list of synonyms 

 already appertaining to this widespread form. 



On Cupipes Guildingii [Neioport).
