OF WASHINGTON. 143 



i. PEPSIS ELEGANS Lep. 



Pepsis elegans Lepeletier de St. Fargeau, Hym., Ill, 



489, c?. 1845. 

 Pepsis elegans Smith, Cat. Hym. B. M., Ill, 201, ?. 



Pepsis dubitata Cresson, Tr. Am. Ent. Soc.-, I, 144, 



cf 9. i867-'68. 



Georgia ; Florida ; Texas. This species seems to be distinct 

 from that described by R. Lucas as auranticornis and to which 

 that author doubtfully refers it. I am of the opinion that ele 

 gans and dubitata are synonymous, and that the red color of 

 the abdominal segments mentioned by Lepeletier in his descrip 

 tion of elegans is, as suggested by F. Smith, "attributable to 

 the iridescence of the pile ..." 



2. PEPSIS CHARON MoCS. 



Pepsis charons Mocsary, Termesz. Fiizetek, 1885, 



225, 9. 



Pepsis charon Cameron, Biol. Centr.-Amer., Hym., II, 



220, ? ef . 



Pepsis charon R. Lucas, Berl. Ent. Zeitschr., XXXIX, 

 589, Pis. 32 and 33, f. 247, ? cf , 1895. 



Mexico (Mocsary, Cameron, Lucas) ; Texas. A single male 

 from the latter locality. 



3. PEPSIS OBLIOJJERUGOSA R. Luc. 



Pepsis ornata Cresson and various authors (non Lep.) 

 Pepsis obliquerugosa R. Lucas, 1. c., 576, ?, 1895. 



St. Thomas (Lucas) ; Cuba ; Mexico ; Lower California ; 

 Arizona. In the hirsute subgenital plate, the male of this 

 species is closely allied to that of P. grossa ; the latter however 

 seems to be restricted to South America.

Sphex sanguigutta Christ., Naturg., 293, pi. 29, f. 3, 



ef. 1791.
