234 Mr. J. O. Westwood's Description, ^c. 



in the genera allied to Leinsma the body terminates in slender 

 elongated filaments. In these however the number is more than 

 two, and the form of the mandibles is also distinct ; but from a 

 review of the general characters of Campodea I think it certain 

 that notwithstanding these minor differences it must be considered 

 as a new genus, more nearly allied to Lepisma and Machilis than 

 it is to any other group of annulose animals. , 



P.S. On showing my drawings of this insect to M. Gervais 

 he immediately recognized it as one which he had found in the 

 garden of his residence in Paris, further stating that he had dis- 

 covered a second species of the same group. 



Can this insect be Lithobius jmsillus* of Van Heyden (Mus. 

 Seek. Bd. 2, 1837, p. 305)?
