PELECINUS. 435 



Pam. PELECINID51. 



This family contains but one genus — the well-known Pelecinus. This genus has 

 been relegated to the Evaniidee by many authors, from which, however, it differs in 

 many respects. In my opinion it is much more nearly allied to the Proctotrupidae, to 

 which Haliday (Hymen. Brit., ' Oxyura,' p. 2) referred it. It may possibly be regarded 

 as the type of a distinct group.

A species of universal distribution in the warmer regions of the New World, ranging 

 from the United States to Brazil. It shows considerable variation in sculpture. A 

 common insect in the forest-region of Guatemala and the State of Panama, ascending 

 from the sea-level to an elevation of about 5000 feet (Champion).

Fam. PROCTOTRTJPID^E. 



The European species only of Proctotrupidse (or " Oxyura " as they are sometimes 

 called) have been at all studied, so it is not possible to offer any remarks on their 

 distribution in the tropics.
