this genus years before Greene's description appeared. 

 Furthermore, the year before Greene used this name with 

 the genus name Bombzis, Kirchner described another species, 

 giving it the name Bombus interruptus, and that would neces- 

 sitate the rejection, as a homonym, of the name interruphis 

 for this species. 



Psithyriis consultus new name. 



Apathus insularis Cresson, Proc. Ent. Soc. Phila., II, 1863, p. 113, cf , 



var. b. (possibly a misidentification) . 

 Psithyrus suckleyi Fletcher and Gibson, Can. Ent. Rec. ("Ann. Rep't 

 Ent. Soc. Ont.), 1908, p. Ill (nom. nud.). 



Types. — Described from thirty-three cotypes, which are de- 

 posited in various collections as follows : United States 

 National Museum, Museum of Brooklyn Institute, Massa- 

 chusetts Agricultural College, Montana Agricultural College, 

 American Entomological Society, Entomological Society of 

 Ontario, Cornell University, and the private collections of 

 Mr. J. C. Crawford and Mr. H. L. Viereck. 



Much reseynbles the fnale of laboriosus, but with some of the dorsal ab- 

 dominal segments beyond the third bearing more or less yellow pile. 



Female. — I believe this species to be the male of P. insularis. See 

 the discussion following the description of insularis. 



Male. Head. — Face usually with a distinct, though sometimes faint, 

 tuft of yellow above the bases of the antennae, and also sometimes 

 with a few yellow hairs between the bases of the antennae, otherwise 

 entirely dark ; occiput with a large triangular patch of yellow pile ; 

 cheeks dark. Malar space shorter than its width at the apex, about 

 one-sixth as long as the eye. Clypeus clothed with black pile. Fla- 

 gellum of antenna about three and one-third times as long as the 

 scape; the fifth antennal segment much longer than the third, the 

 third somewhat longer than the fourth. 



Thorax. — Dorsum yellow, with (rarely without) a black band be- 

 tween the bases of the wings, this band being rather poorly defined, 

 and very often extending back, in the middle, onto the middle of the 

 scutellum ; mesopleura mostly covered with yellow pile to the bases of 

 the legs ; metapleura variable, sometimes with mostly dark and some- 

 times with mostly yellow pile ; sides of the median segment mostly 

 dark. 



Abdomen. — Dorsum : segment one yellow ; segment two yellow, 

 but often with more or less black pile on each anterior corner ; seg- 

 ment three yellow ; segment four sometimes mostly covered with yel-
