This is partially owing to the fact that the collecting of.Dermaptera is difficult due to the secretive habits of the majority of the species and the great diversity of habitat. [...] In the preparation of the present paper we have been particularly interested in finding that the contrast between the brachylabic and macrolabic phases of certain species is not only manifested by differences in the male forceps but also by changes in the pygidium ultimate tergite and even by slight differences of proportion in the pronotuun as well. [...] As elsewhere in that paper however we feel that the external structure should have been much more thoroughly studied and that the characters of the metaparameres and virga should have been added to a general description of the external morphology in separating the genera particularly in the case of the genus described as new. [...] The measurements of the two males before us are as follows those of the type being given first : length of body 14 and 14.2 length of pronotum (exclusive of neck) 2.14 and 2.35 width of pronotum 2.31 and 2.52 length of tegmen 0.88 and 1.04 width of tegmen 1.22 and 1'43 length of forceps 2.9 and 3.1 turn. [...] The latter specimens are exceptionally large and heavy for the species the male showing the maximum curvature of the forcepg developed which closely resembles the normal type of these appendages developed in E. rims& (Gene).* The specimen from Santikoppa is very remarkable in possessing truncate tegmina which overlap and reach slightly beyond the caudal margin of the mesonotum.
