I have examined a specimen in the Boerner collection at the BMNH labelled A. socialis by Boerner, and also specimens labelled as cotypes of P. nivicola Fitch which are in the USNM (3 specimens on slide No. 5216). Considering the age of Fitch's specimens they were in a remarkably good state of preservation and figures 146-150 of this paper were drawn from them. Figs. 143-145 are from Boerner's specimens in BMNH. From these examinations it is clear that the synonomy suggested by Schott (1893) and adopted in my "Index" in 1964 is correct. H. nivicola was redescribed and illustrated by Stach (1949, pp. 71-77, pl.iv). Stach's figures of the species agree very clearly with those given here from Fitch's type material. The species would seem to be very widely distributed over the Northern Hemisphere.

Since these cotypes of Fitch were available in the USNM for Folsom to study, the suggestion made by Folsom (1916, p.485) that Fitch's name be suppressed in favour of socialis is quite out of order.
