*2. Pelocoris femoratus (Palisot de Beauvois). 

 "From under floating weed" in "the Hunts Bay Biver, 

 St. Catharine." 



*3. Belostoma colossicum (Stal.). 

 No special locality. 



*4. Belostoma annulipes, Herrich-Schaffer. 

 No special locality. 



*5. Ranatra annulipes, Stal. 



The vicinity of Kingston is not favourable to the collection of 

 waterbugs, as there are no ponds or pools of still water. From 

 an ornamental tank (Constant Spring, St. Andrew), "about two- 

 thirds full of tepid foul water, the surface entirely covered with 

 confervae," an hour's work produced this species and fragments 

 of a Notonecta. 



6. Notonecta undulata, Say. 



Mr. Taylor informs me that this species " comes to ' light ' 

 in great numbers, and is often a great nuisance at the dinner- 

 table." 



St. Andrew, four or five miles from Bae Town ; Balaclava, 

 St. Elizabeth (middle of the island). 



* The species preceded by an asterisk have been kindly examined by 

 Dr. Montandon also.
