small, more or less confluent craters not unlike the nests of F. 
subsericea in grassy places in the Eastern States, or of F. cinerea in 
sandy river valleys of Southern Europe. It is readily enslaved by the 
forms of sanguinea inhabiting the same region. ‘The males and winged 
females mature during the latter half of July. 
Mr. Geo. B. King has recorded the variety neoclara from Essex 
County, Mass., and I possess eight specimens bearing labels with this 
locality. They resemble Colorado specimens very closely, except 
that the petiole is not emarginate and therefore not cordate when 
seen from behind, and the gaster is not infuscated. These specimens 
may represent a distinct .variety. If they are really specimens of 
neoclara, 1am unable to account for their occurrence in Massachusetts 
unless they were accidentally introduced from the West. Of course, 
the locality labels may be erroneous. 
91. F. FUSCA FUSCA var. BLANDA, var. nov. 
WorkeER. Length 3-3.5 mm. 
Resembling neoclara, but smaller, with the whole body reddish 
brown, the legs, antennae, and mandibles paler, the head, gaster, and 
tips of funiculi not infuscated. Subopaque and very densely and 
finely punctate or shagreened, the head and gaster slightly shining. 
Frontal area opaque. Hairs and pubescence white, the former short 
and very sparse, absent on the thorax, the latter very fine and short, 
rather dense on the gaster, shorter on the head and thorax. Thorax 
with very feeble mesoépinotal constriction, epinotum rather long, 
obtusely angular in profile, its base longer than the declivity which is 
very sloping. Petiole rather thick and blunt, with entire and rounded 
superior border. 
Described from a dozen workers taken by Prof. Trevor Kincaid at 
Olympia, Washington (type locality), six workers taken by the same 
collector at Seattle, Wash., two workers taken by Mr. J. C. Bradley 
in the Yosemite Valley and four workers taken by the same collector 
at Lemon Cove, Tulare County, California. The status of this 
variety is somewhat problematical. It may be merely a very pale 
form of the var. marcida, although there is little variation in the series 
of workers examined. They differ from the worker neoclara in the 
uniform brown color of the body, the shorter and more delicate pubes- 
cence, the absence of a notch in the petiolar border, the narrower head 
and smaller size.
