is the male of mixtits, and not that of frigidus as was sup- 

 posed by Cresson : 



1, Similarity of coloration. — Its thoracic dorsum, except the scutel- 

 lum, bears mixed black and yellow pile like the mixtus worker. The 

 worker also often has the second dorsal abdominal segment entirely 

 covered with j^ellow pile. 



2. Sifnilarity of distribution. — It is found wherever the females of 

 mixtus are found and in corresponding abundance.

Types. — Described from eight queens (cotypes) and twelve 

 workers (cotypes), deposited in the collection of the United

 in the same collection. One queen and one worker (para- 

 types) are in the collection of the Massachusetts Agricul- 

 tural College. 



Pile rather long and of medium texture. Face dark ; occiput vari- 

 able in coloration ; thorax with dorsutn yellow, except for black inter- 

 alar band ; lower portions of pleura dark ; abdom-en with dorsum yel- 

 low at base, black in the middle and white at the apex ; wings rather 

 light. Malar space rather short. 



Queen. Head. — Face entirely dark; occiput entirely dark, or with 

 black and yellow pile mixed, or even with a triangular patch of pure 

 yellow pile ; cheeks dark. Labrum with tubercle-like areas moderately 

 separated, their margins rounded and summits strongly concaved ; 

 the shelf-like projection moderately wide and prominent. Malar space 

 shorter than its width at the apex, about one-fifth as long as the eye. 

 Clypeus sparsely and unevenly punctate over the disc. Flagellum 

 of antenna about twice as long as the scape ; third antennal seg- 

 ment distinctly longer than the fifth, the fifth slightly longer than the
