NO. 1806. BEES IN THE NATIONAL MUSEUM. l.—COCKERELL. 643 



Known from H. Icrishna Bingham by the deep yellow face markings 

 of male (face marks white in Tcrishna) ; from H. fulvipes Cameron by 

 the absence of light face marks in the female, and the dark legs (legs 

 are fulvous in iemale fulvipes) ; from H. montana Radoszkowski by 

 the dark, pale-banded abdomen (abdomen densely covered with hair 

 in montana); from H. magrettii Bingham by the black flagellum of 

 the male and the darker legs; from H. modleri Bingham by the dark 

 abdomen (abdomen and legs honey-yellow in mcdleri); from H. 

 halassogloi Radoszkowski by the black flagellum of the male, etc.; 

 from H. tumeri Cockerell by the unicolorous hair of thorax^ etc. 



ANTHOPHORA ZONATA (Linnaeus). 



Four from Foochow, China (H. R. Caldwell). 



ANTHOPHORA FIMBRIATA Smith. 



Khow Sai Dow Mountain, 1,000 feet. Lower Siam (W. L.Abbott); 

 Trong, Lower Siam (W. L. Abbott). These females differ from the 

 type as described by Bingham and Smith by having the metathorax 

 black-haired. The hair of the thorax above is not "grey," as Bing- 

 ham states, or " bluish- white, tipped with black," as Smith has it, 

 but is very pale blue mixed with black. This species strongly imitates 

 Mesotridiia ahhotti Cockerell, which lives in the same region. 



MEGACHILE XYLOCOPOIDES Smith. 



Five females, Mansfield, Louisiana, at flowers of Helenium tenui- 

 folium, July 4 and August 22 (F. C. Bishopp). 



MEGACHILE VELUTINA Smith. 



One female, Khow Sai Dow Mountain, 1,000 feet. Lower Siam, 

 February, 1899 (W. L. Abbott) ; five females, Trong, Lower Siam, 

 January, February, 1899 (W. L. Abbott). Only one (Trong) has the 

 first two abdominal segments with red hair ; the others have the first 

 and basal part of second with red hair. The allied M. dimidiata 

 varies in the same manner, according to Bingham. The one from 

 the mountain is smaller than the others. 



HETERANTHIDIUM CHIPPEWAENSE (Graenicher). 



I am indebted to Doctor Graenicher for a cotype of his Anthidium 

 chippewaense; it proves to belong to Tleter anthidium. 



DLANTHIDIUM ILLUSTRE (Cresson). 



At Flagstaff, Arizona, at flowers of his, June 11, 1909, Mr. F. C. 

 Pratt took a large variety of the female of this species, about 17 mm. 

 long, the width of the abdomen fully 6 mm. The wings are very dark; 

 the first r. n. joins the second s. m. a short distance from base (as in
