424 AMERICAN HYMENOPTERA. 



and the inner lobe nearly one-half as large as the outer one ; volsellse 

 long and rather slender, extending considerably beyond the tips of the 

 squamae. Sagittae with broadly foliaceous sickle-shaped heads, the 

 outer portions of their margins strongly serrate ; shafts straight and 

 somewhat hairy, especially toward their bases on their upper and outer 

 sides ; uncus tapering gradually, narrow except towards the base, this 

 being fairly broad. 



Wings. — Dark, but usually somewhat lighter than those of the 

 queen. 



Legs. — Dark. Posterior tibiae with outer faces sometimes bare and 

 sometimes with a sparse scattering of short hairs, their fore and hind 

 fringes rather short. Posterior metatarsi about three and one-half 

 times as long as their greatest width, with hind fringes long and usu- 

 ally mostly black, but often more or less ferruginous, especially toward 

 the apical end ; their outer faces flat, or slightly concaved, and strongly 

 and evenly pubescent. 



Dimensions. — Length : queen, 21 mm. to 25 mm. ; worker, 13 mm. 

 to 21 mm.; male, 13 mm. to 22 mm. Spread of wings: queen, 50 

 mm. ; worker, 30 mm. to 42 mm. ; male, 42 mm. Width of abdomen 

 at second segment : queen, 11 mm. to \\\ mm. ; worker, 6 mm. to 9 

 mm. ; male, 9 mm. 



Redescribed from six queens (two of them homotypes of 

 B. scutellaris Cresson), a large series of v^orkers (two of 

 them homotypes of scutellaris) and eleven males. 



Habitat. — This species ranges through the following states 

 of the United States : Texas, Louisiana, Mississippi, Ala- 

 bama, Georgia, Florida, South Carolina, Oklahoma, Arkansas, 

 the greater part of Tennessee and of North Carolina, Kansas, 

 Missouri, Kentucky, the eastern half of Virginia and of Mary- 

 land, Delaware, a considerable portion of New Jersey (Glou- 

 cester County, Anglesea, Lakehurst and Lancaster), Ne- 

 braska, Iowa, Illinois, Indiana and a considerable portion of 

 Ohio. It also occurs in the eastern part of Colorado (Fort 

 Collins, Hugo, Berkeley) and of New Mexico (Las Vegas) and 

 in the southern part of Michigan. It probably ranges through 

 a considerable part of Mexico, and probably is present in por- 

 tions of Arizona, eastern Wyoming, the southern half of South 

 Dakota, southern Minnesota and southern Wisconsin and the 

 western part of West Virginia. It would be interesting to 

 know if it is present in the southeastern part of Montana, 

 the extreme southern part of Ontario (in Canada), and in the
