FORMICA EXSECTA IN JAPAN
BY WILLIAM MORTON WHEELER,
Bussey Institution, Harvard University.
Among several Japanese ants recently handed to me for identi- fication by Mr. W. M. Maim there are a few specimens repre- senting an undescribed variety of Formica insecta. This species, though well known from northern and central Europe and Siberia, has not been taken hitherto east of the Altai Mountains of Mon- golia.
Formica exsecta Nylander var. fukaii var. nov, Worker: Length 5-6 mm.
Differing from the worker of the typical form in having the mesonotum in profile straight and sloping gradually to the mes&pinotal constriction, instead of convex. The notch in the superior border of the petiole is distinctly narrower and shallower, the gftster is darker, being black throughout and not red at the base of the first Pwhr 21:26 11914). htlp:ffpsyclK.i'nlclub.ora/21/21~026 hlml
