Described from one female, and one worker (cotypes) in 

 the collection of the U. S. National Museum. Five female 

 paratypes and one worker paratype are also in that collection. 



Subspecies laticollis. — 9 . — Like the typical nigrodorsalis 

 except that the band of yellow pile running across the anterior 

 part of the dorsum of the thorax is much wider and reaches 

 back in the middle to even with the tegulae. Middle and hind 

 coxa? and bases of posterior femora within bearing consider- 

 able yellow pile. Posterior fringes of corbiculae strongly 

 fulvous. 



Described from one female (type) in the collection of the 

 U. S. National Museum. 



Specimens collected by C. H. T. Townsend in Meadow Val- 

 ley head of Rio Piedras Verdes (6 miles south of Colonia Gar- 

 cia). Sierra Madre of Western Chihuahua, Mexico — about 

 7,000 ft. alt. 



Some of the specimens of this species have the coxae and 

 posterior femora, as well as the fringes of the corbiculae, all 

 black. The coxae of the workers sometimes bear yellow hairs 

 and their corbicular fringes are sometimes tinged with light 

 or fulvous color. 



This species may prove to be only a variety of B. zveisi 

 Friese, which in turn is possibly only a form of B. ephippiatus 

 var. laboriosus Smith, but, if this is the case, then certainly 

 laboriosus Smith and pidchcr Cresson should not be included 

 as varieties of the same species, as they are listed by Dalla 

 Torre on the authority of Handlirsch. B. nigrodorsalis 9 has 

 a distinctly longer malar space than has B, pidcher 9 , and this 

 is an exceedingly constant specific character in Bombus. 



Bombns haueri Ant. Handlirsch. 



9. — Length, about 23 mm. — Malar space somewhat wider at the apex 

 than it is long. Clypeus rather strongly punctate. Third antennal 

 segment fully as long. as the fourth and fifth taken together. Ocelli 

 large, placed below the supraorbital line, in the narrowest part of the 

 front. Hypopygium without median carina. Head with face, occiput 

 and sides behind the eyes all black. 



Thorax with anterior part of dorsum and the metanotum densely 

 covered with deep yellow pile. A broad band between the bases of 

 the wings and the pleura from the level of the tegulae to the bases of
