HYPOCTHONIUS PALLIDULUS. 637 



obtained after oviposition and bred. There is not any- 

 thing special about it otherwise to call for observation ; 

 it is rather transparent and slightly chitinized. In the 

 specimen figured (fig. 8) segmentation is considerably

Distribution. — The creature lives in moss on the 

 ground on fresh green banks, chiefly in spring; it is, I 

 think, generally distributed, but is not common. It 

 has been recorded in Germany, France, and Swit-
