NEW NOKTH AMERICAN BOMBID^E.

The author has, for several years, had in process of prepa- 

 ration a monograph of the Bumble-Bees, {Bomdus) and the 

 Inquiline Bees {Psiihyriis) of the entire New World, and it 

 was his expectation to have published this work this spring. 

 The pressure of other work, however, makes it necessary to 

 put off this publication, for a few months, though the paper 

 is near completion. 



Under the circumstances, it seems best to publish, in a 

 short advance paper, the descriptions of the following spe- 

 cies : these species being the more important of the new 

 North American forms, which have been discovered in the 

 course of these investigations. 



Bombiis (Boinbus) fernaldi new name, 

 Bombus ewardsii Fowler, Rept. Cal. Agr'l Exp. Sta. 1902, Part II, 

 p. 317 (misidentification) . 



The specimens from which Fowler made his description of 

 this species, having mistaken it for ediaardsii, may be looked 

 upon as the type specimens. Can those specimens be identi- 

 fied with certainty ? 



Pile of medium length and rather fine. Face and occiput with much 

 yelloiv pile ; thorax, except for a usually broad black interalar batid, 

 clothed zvith yellow pile ; dorsum of abdomen luith basal segment yellow, 

 segments tivo and three usually e7itirely black, four and five largely 

 yellow and the apex usually black. Corbicular fringes of females dark. 



Queen. — Head. — Wide for its length. Face mostly covered for some 

 distance above and below the bases of the antennae with a patch of 

 pure yellow pile ; occiput with a median triangular patch of yellow 

 pile with a slight admixture of black hairs ; cheeks dark. Labrum 

 with tubercle-like areas having their posterior (proximal) margins 

 rounded and their summits flat or concaved, the region between them 

 and above the shelf-like projection rather deeply excavated ; the shelf- 

 like projection not prominent. Malar space fully as long as its width 

 at apex ; between one-fifth and one-fourth as long as the eye. Clypeus
