Note 1. Zimsen (1964) could not find specimens labelled Formica bicolor in the Fabricius collection, and he supposed that the types should be in the collection of René Louriche Desfontaine, in the MNHP in Paris, but no such types could be found there.
Note 2. The types of megalocolus could not be found in the Foerster collection ZMHB (Koch, personal communication). Forel (1890a: 4, 9; also 1890b: 67) describes this race as a rather constant, scarlet form with a distribution on the Tell (eastern part of the Atlas mountains) being smaller than the reddish-black viaticus s. str. with a further southern distribution, to the oasis where he could not record megalocolus. Whereas viaticus builds nests at the edge of the palm forests in rocky soil, megalocolus excavates its nest in the grassland. This observation is confirmed by Wehner etal. (1983: map 2) where they mention a light and a dark form of bicolor in Tunisia. Emery (1891: 16) also described the male of megalocolus smaller than the male of viaticus, but doubted whether this male was correctly identified as megalocolus.
Note 3. The types of fairmairei could not be found in the Foerster Collection ZMHB (Koch, personal communication).
