Crematogaster excisa subspecies impressa variety euphrosyne Santschi ^HNS, new variety

"Worker.-Length 3.5 mm. More or less pale chestnut brown. Thorax narrow. Pronotum reticulate-punctate in the spaces between the fine longitudinal rugae. Mesonotum feebly carinate in front. Resembles the variety brazzai Santschi ^HNS,1 but the latter has a broader thorax, without carina and the sculpture of the thorax is merely reticulate." (Santschi)

K-Tiginally described as a subspecies of C. impressa ^HNS and given in our catalogue (Part VIII) as C. menilekii subspecies occidentalis variety brazzai ^HNS.

Faradje (type locality) and Thysville (Lang and Chapin). The specimens at Faradje were found "nesting in hollow twigs. Snails (Pachnodus herbigradus Pilsbry) were found estivating in the same twigs inhabited by the ants and often in such numbers as to clog the passages." Camponotus foraminosus ^HNS was found in similar hollow branches together with the same snails (see p. 248).
