112 MATUTA LUNARIS. 



Besides these , our collection contains 70 specimens 

 without locality, for the greater part belonging to the rar: 

 crebrepunctata mihi. 



This species has a wide geographical range , from the 

 Red Sea to the Australian shores throughout the whole 

 Indian Ocean and the Malayan Archipelago; it presents 

 however many local and individual varieties as regards the 

 coloration of the carapace and the more or less distinct 

 tubercles with which it is armed.
