ings on the upper surface of the thorax are more or less confluent. First and 

 second gastric segments each often with a broad, red or yellowish, transverse 

 band above. Antennae red, funiculi infuscated towards their tips. Legs red 

 or yellowish. 



Male. — Length 6-6.5 mm. 



Indistinguishable from the male of nearcticus except, perhaps, by its 

 slightly smaller average stature. 



The types of this variety came from the District of Columbia, 

 Maryland, Missouri and New Jersey. I have examined specimens 

 from the following localities : 



New Jersey: Great Notch and Cumbridge County (H. Viereck) ; 

 Ramapo Mts. and Lakehurst (Wheeler and W. T. Davis). 



New York: Jamaica, L. I. (N. Y. State Coll.). 



Pennsylvania: St. Vincent (Jerome Schmitt). 



Massachusetts: (Geo. B. King). 



Illinois: Rockford (Wheeler). 



British America: Canada (J. G. Jack); Vancouver (Mus. Comp. 

 Zool.). 



This variety, which is merely a paler and depauperate form of 

 nearcticus, is extremely variable in color. A number of worker 

 specimens in my collection from Bronxville, N. Y., have two dark 

 spots on the pronotum and have the epinotum more or less infuscated 

 above. They form a transition to the next variety. A series of 

 forms taken by the Rev. Jerome Schmitt at St. Vincent, Pa., and com- 

 prising all four phases, have the larger stature of nearcticus with 

 the coloration of minutus. Some of the females of this series have 

 the thorax entirely black above, others have the characteristic macula- 

 tion of miuiitits. The workers, too, are highly variable in color.

This form has the small dimensions of minutus but the thorax, legs and 

 antennae of the worker major and minor are ivory yellow, the thoracic dorsum 

 with dark brown spots, the legs and antennae variegated with brown. The 

 head has the anterior portion brownish, the cheeks, clypeus and mandibles 

 ivory yellow. In some major workers the yellow runs back some distance in 

 clouds between the eyes and the frontal carinae. In many specimens the 

 middle portions of the first and second gastric segments are more or less 

 yellowish. The female measures 8 mm. and has the thorax, petiole and legs 

 clay yellow; the thorax has the black markings of the minutus female, with
