798 Hymenoptera in America North of Mexico 



Evidently it is difficult to spell this generic name. Thomson, 1878 (Hym. Scand., v. 5, p. 37) 

 spelled it Raphitelus and Kurdjumov, 1913 (Ent. Obozr. 13: 4) spelled it Rhaphiteles. Gahan and 

 Pagan, 1923 (U. S. Natl. Mus., Bui. 124: 138) spelled its synonym Styloceras as Stylocerus.
