530 PROCEEDINGS OF THE ACADEMY OF [1895. 



21. Gorytes rugosus Pack. 



Gorytes rugosus Packard, 1. c, p. 427, $ . 



Brunswick, Maine (Packard). Unknown to me. This will, no 

 doubt, eventually prove to be the $ of nebulosus. 



22. Gorytes armatus Prov. 



Gorytes armatus Provancher, Add. Hym. Quebec, p. 272, $ . 



Ottawa, Canada (Provancher). Unknown to me. This species 

 is said to have the mandibles spined near the base on "superior" 

 margin. The occurrence of such a character in Gorytes is question- 

 able ; and it is not unlikely that Provancher has been misled by the 

 lateral bunches of hair, with which the clypeus of the males of this sec- 

 tion is furnished, and which frequently present a waxy appearance, 

 thereby resembling a spine to some extent. The removal of this 

 character from consideration suggests the uniting of armatus with 

 rugosus. 



23. Gorytes barbatulus Hdl. 



Gorytes barbatulus Handlirscb, 1. c, p. 40S, $ . 



Illinois and Texas (Handlirscb.) ; Agricultural College, Missis- 

 sippi (H. E. Weed) ; District of Columbia. The feniale specimens, 

 doubtfully referred to barbatulus by Handlirsch, belong to denti- 

 culatus. 



24. Gorytes denticulatus Pack. 



Gorytes denticulatus Packard, Proc. Ent. Soc, Phila., VI, p. 430, $ (non 9 ). 

 Gorytes barbatulus (iu pt.) Handlirsch, 1. c, p. 410, 9 • 



Florida; Georgia; Louisiana; Mexico. Handlirsch is right in 

 assuming Packard's type to be a $ , instead of a 9 , as I have ex- 

 amined the type. The middle segment may or may not be yellow- 

 spotted, and the first abdominal segment is sometimes variegated with 

 rufous. I have no doubt but that denticulatus is identical with 

 plaeidus, which I have not seen. 



25. Gorytes plaeidus Sm. 



Gorytes plaeidus Smith, Cat. Hyui. B. M. IV, p. 368, $ 9 . 

 Gorytes rufipes Smith, ibid, p. 369, 9 • 

 Gorytes plaeidus Handlirsch, 1. c, p. 530. 



East Florida (Smith). Unknown to me. I fully agree with 

 Handlirsch in uniting plaeidus and rufipes. 



26. Gorytes spilopterus Hdl. 



Gorytes spilopterus Handlirsch, 1. c, p. 414, 9 , P^ Ij f- 18. 



Colorado; Nevada; Montana; Washington State.
