ON THE HYMENOPTERA OF CUBA. 



BY E. T. CRESSON. 



( Communicated November 14, 1S64.) 



The materials used in the preparation of this paper are derived prin- 

 cipally from the fine original collection of Prof. Felipe Poeyof Havana, 

 Cuba, procured and most generously presented by Dr. Thos. B. Wilson 

 to the Entomological Society of Philadelphia; also from the uniques in 

 the collection of Dr. John Grundlach of Cuba, who has kindly loaned 

 them to me. and who possesses, probably, the most complete collections 

 extant of all orders of Cuban Insects. 



To Prof. Poey and Dr. Guudlach, I am greatly indebted for valua- 

 ble notes upon the habits, &c, of many species. 



Most of the Chalcididse, the Proctotrupidse and the FormicidaJ. have 

 been reserved for future papers, as the minute size of many of them 

 require careful study, and specimens in good condition, before reliable 

 descriptions can be made. The collection before me contains, of Chal- 

 cididse and Proctotrupidai about 80 species, and of Forinicidae about 00 

 species; of the latter many have been described by Roger and Mayr. 

 Of the other families, including the larger Chalcididse, over 300 species 

 are enumerated below, of which number about 250 seem to be new.
