Doru dohrni sp.nov. (Figs. 49-51) Dark brown, easily recognizable by its snow-white wings. In coloration, highly resembling Doru leucopteryx Burr from Venezuela. Pronotum quadratic, anicolorous, lateral margins nearly parallel. Elytra long, more than twice longer than wid> . Wings white, well developed (Fig. 49). Posterior margin of last tergite with 10 minute pegs, again as in Doru leucopteryx Burr, but arranged otherwise, in leucopteryx the two extreme pairs are ^.bove each other, in the new species beside each other. Male cerci longer, the pair of teeth situated medially on the cerci in leucopteryx Burr, but in the special fifthe in dohrni sp. nov. No pegs or appendages on dorsal surface of cerci (Fig. 50). Male genital organ further substantiating its specific distinctness (as also suggested by its peculiar distribution). Paramere relatively short, narrow, hardly longer than length of metaparameres; these latter very characteristic, parallel for a longer section, and curving inwards only near their apices. (Those of the typical Doru species describe, on the other hand, a full arc, or ellipsis, along their entire length). Genital lobe unpaired, also very striking, conspicuously widening at its anterior, transversely truncate margin (Fig. 51). Virga medium long, basal vesiculum not of the Doru type, but rather forficuloid: stringly curved, with a characteristic lateral sac at the beginning of its curvature. - Length of body (without cerci): 11.2 mm, cerci of male: 4. 1 mm. Female unknown. Holotype male: N. Guinea, Typus, (gen. prep. No. 378, det. D \ H. Steinmann). Deposited in the PAN Instytut Zoologiczny, Warszawa. I dedicate the new species to Dr. H. DOHRN, the outstanding worker in Dermaptera, and the more so as he also realized the distinctness of the new species and distinguished the specimen in his collection by a label "F. wallacei sp. nov

Cerci gradually and arcuately curved, tooth of inner margin in apical third of cerci (Fig. 52). Anterior margin of unpaired genital lobe constricted (as in all Doru species), metaparames strongly widenea in basal section.Distribution: Australia (New South Wales) , ... , 1on
