Wheeler, A Netv Oiiest-ant.

Female. Lengi:h 5 — 5.5 mm. Eesembling the worker. Thorax 
yellowish brown with the metanotum, posterior border of scutellum, 
an anteromedian, often double, blotch and two large parapsidal blotches 
on the mesonotum, black. Wings distinctly brown at the base, with 
brown veins and stigma. 
Male. Length 5 — 5.7 mm. Closely resembling the male of the 
var. sulcinodoides, and with equally short antennal scapes. The wings, 
however, are of a deeper brown at their bases, the mesonotum is more 
densely and more extensively striated, and *the hairs on the legs are 
shorter and stiffer. 
Connecticut: Colebrook, Litchfield County, 1,000-1,600 feet. 
Massachusetts: New Boston, Berkshire County, 1,400 feet. 
Maine: (Pergande) ; Ogunquit (H. S. Piatt). 
Pennsylvania : Lehigh Gap. 
Michigan: Marquette (M. Downing); Tsle Royale (O. 
Gleason) . 
Wisconsin: Milwaukee (C. E. Brown). 
Nova Scotia: Digby (J. Russell). 
British Columbia: Golden (W. Wenman). 
This is the only form of brevinodis which descends to lower 
levels in the Northern States. Transitional forms between it and 
the true sitlcinodoides undoubtedly occur. Females from several 
of the Nova Scotia colonies have the thorax nearly black, and the 
workers of many colonies from the same region are almost yellow, 
with only the posterior portion of the head and a broad band 
across the gaster dark brown. The var. canadensis rarely reaches 
as great a size as the variety to which I have restricted the name 
sidcinodoides, and nests in cool bogs or meadows, under stones or 
logs. Its larvae and young pupae are pearly white and not 
greenish yellow. 
6. Var. subalpina var. nov. 
Worker. Length 4—5 mm. Eesembling canadensis in color but 
differing both from it and sulcinodoides in having the hairs on the 
body obtuse, instead of pointed, and somewhat stouter than in the 
other varieties. 
Female. Length 4.8 — 5 mm. Colored like the female of canadensis, 
but with the wings whitish hyaline throughout, with very pale brown
