NORTH AMERICAN HYMENOPTEKA. 169 



A generic $iyiiop!<iis of the hyineiiopterous Family 

 PRO< TOTRl PIDJE. 



BY L. O. HOWARD. 



This large family has been but little studied in this country, al- 

 though considerable material for study is to be found in the various 

 collections. I have been able to pay but little attention to the gi'oup, 

 and this synopsis is nearly a literal translation of that which appears 

 in Part II of Dr. Foerster's " Hymenopterologische Studien," 

 Aachen, 1856. I have inserted, however, several of his more re- 

 cently erected genera taken from his " Kleine Monographien," and 

 also one or two others which have been described since. The divi- 

 sion into subfamilies which immediately follows is faulty in the ab- 

 .sence of the subfamily BETHYLiNiE, a generic synopsis of which is 

 included later. My excuse for this omission is ignorance of the gen- 

 eral characters of this subfamily, which, together with the Embo- 

 leminae, is omitted by Foerster frorn his subfamily synopsis. I 

 have been unable to find a copy of Haliday's " Hymenojiterorum 

 Synopsis" in America in which the characters of this subfamily are 

 presumably given, and while this synopsis is being printed Prof 

 Riley is kindly searching for this paper in English libraries. I am 

 advised, however, not to defer publication on this account. I have 

 prefixed an asterisk to those genera, species of which have been 

 published as found in America north of Mexico, and a dagger to 

 those which I have myself recognized in collections (mainly in Prof 

 C. V. Riley's, now the property of the National Museum by dona- 

 tion), but which have not yet been published as American. Of 

 the one hundred and thirteen genera mentioned in the synopsis, 

 but twenty-nine have thus far been found in this country.
