Some Anthidiine Bees. 



BY T. D. A. COCKERELL. 

 HETERANTHIDIDM Ckll., 1904. 



To this genus must be added Heteranthidium occidentals 

 (Anthidium occidentalc Cresson) and H. sebratum (Anthid- 

 iiun zcbratum Cresson). Mr. S. A. Rohwer has taken H. 

 zcbratum at Boulder, Colorado, during the latter part of Au- 

 gust, at flowers of Helianthus pumilits. 



Dianthidium inerme (Friese). 



Anthidinm inerme Friese, 1908. Mendoza, Argentine. I 

 am indebted to Dr. Friese for a specimen. 



Dianthidium zebra (Friese). 



Anthidium zebra Friese, 1904. Willowmare, Cape Colony. 

 My specimen is from Dr. Brauns. 



A. brannsi Friese has no pulvillus, and belongs to Anthid- 

 ium. 



Dianthidium siculum (Spinola). 



Anthidium siculum Spinola, 1838. My specimens are from 

 Tangier and Rabat, Morocco. 



Dianthidium ulkei (Cresson). 



A series from Colorado and New Mexico, which I have 

 hitherto referred to D. parvum (Cress.), includes two distinct 

 things, the commoner one being D. ulkci. This is readily sep- 

 arated from D. parviun and other allies by having the tibiae on 

 the outer side wholly yellow in both sexes. The seventh seg- 

 ment of the male abdomen is broadly truncate, yellow with 

 the edge hyaline, the lateral corners rounded, and the small 

 median projection not bounded by notches. The hind coxse 

 have yellow spines. In the female, the dot above clypeus, and 

 those behind the ocelli, mentioned in Cresson's description, 

 are more often absent than present. The specimens of D. 

 ulkei before me come from the following places: Campus of 

 University of Colorado, Boulder, Colorado, July 15 (Ckll.) ; 

 Boulder, Colo., at flowers of Grindelia serrulata, Sept. 3 

 (Ckll.) ; S. Boulder Canon, Colo., at Grindelia, Aug. 9 (Ckll.) ; 

 Raton, New Mexico (W. P. Ckll.); Pccos, New Mexico (T. 

 D. A. & W. P. Ckll.).
