Dianthidium (Paranthidium) jugatorium Say. 



Two males from Omaha, July 8 and 13, 1914 (L. T. Williams) ; 

 the first one on Melilotus alba. 



Dianthidium (Dianthidium) sayi Cockerell. 



A new locality record is Mitchell, Scottsblufl: comity, Nebraska, 

 where Mr. L. M. Gates collected four females July 11 and 14, 

 1914, on Cleome serrulata. 



Dianthidium (Dianthidium) concinnum (Cresson). 



Evidently a common species in Kansas, the University of 

 Kansas collection containing female specimens from Rooks, Gra- 

 ham, Ness, Norton, Sheridan, Morton, Cheyenne and Greeley 

 counties, July 7 to August 24 (F. X. Williams). I have not seen 

 this species from Nebraska. 



Dianthidium (Dianthidium) consimile (Ashmead). 



A pair from the Santa Rita Mountains, Arizona, 5-8,cx)0 feet, 

 July (F. H. Snow), and two males (July) and a female (Au- 

 gust), from Oak creek canyon, Arizona (F. H. Snow), agree 

 exactly with the characters assigned this species by Ashmead and 

 Cockerell and are without hesitation referred to it. 



Dianthidium (Dianthidium) texanum (Cresson). 



A male from the Santa Rita Mountains, Arizona, July (F. H. 

 Snow), agrees exactly with Cresson's description except that the 

 abdominal bands are clear yellow and those on tergites i and 2 

 are interrupted like those on tergites 3-5. 



Dianthidium (Anthidiellum) gilense Cockerell. 



This species, which has previously been recorded from New 

 Mexico and Texas only, is represented in the University of 

 Kansas collection by four females and eleven males collected by 

 F. H. Snow in southern Arizona during July and August, prin- 

 cipally at Oak Creek canyon. The female pygidium usually has 

 two yellow or feruginous spots or bars, though sometimes it is 

 wholly black.
