THE CANADIAN ENTOMOLOGIST 403 



lobes about one and one-half their breadth apart, pygidial area 

 coarsely punctate, sides parallel, about one and a third times as 

 long as broad; enclosure as in female. 



Length 11 mm. 



From Fargo, N. Dak., July 7 to Sept. 6 (Stevens coll.), 

 on Solidago serotina. In Swenk's table it runs to' imitator ia, but 

 in that species the band on the second segment is no broader than 

 the others. 



Cerceris floridensis, n. sp. 



The male runs to C.morata in my table, but larger, the hair-lobes of 

 clypeus much narrower, and the enclosure different. Head broad, 

 face reddish, clothed with white hair; clypeus prolonged in middle, 

 the hair lobes small, fully three times their width apart; antennae 

 pale on base, and extreme tip; vertex and back of eyes reddish, 

 pronotum, teguke, spot beneath on side, scutellum, postscutellum, 

 large spot on sides of metanotum, first and second segments of 

 abdomen above and below, reddish or yellowish red; legs mostly 

 yellowish red. Wings blackish, marginal cell black, stigma yel- 

 lowish; second submarginal twice as long as high. Body very 

 coarsely punctate, enclosure large, smooth, faint traces of striation. 

 Abdomen broad, basal segment much broader than long, but little 

 more than one-half as wide as the second. Pygidial area hardly one 

 half as wide at tip as at base, once and a half as long as broad at 

 base, coarsely punctate. Last joint of antenna longer than pre- 

 ceding, curved. 



Length 14 mm. 



From Gulfport, Fla. (Reynolds). In general it is related-'to 

 C. gnarina. 



Cerceris carrizonensis, n. sp. 



In the New Mexico table this runs to C. convexus; it differs in 

 the marginal cell being not black, but hyaline, and in lacking a 

 spot on pleura behind the tubercles. 



Male small, black, face below antennae yellow, enclosing a black 

 dot each side at angle of clypeus; basal joint of the antennae yellow, 

 next black, beyond brown. Two spots on the pronotum, tegulae, 

 two spots on the scutellum, the postscutellum, band across basal 

 segment, rather narrow band at apex of each of the other segments.
