ORTHOPTERAFAM. BLATTI DAESUBFAM. BLATTINAE (=PERIPLANETINAE)By R. SHELFORDWITH 2 COLOURED PLATESGen. Insectorum Fas. 109
THE Blattinae (Periplanetinae) form the fourth subfamily of the Blattidae.
Characters. -- Antennae setaceous and usually much longer than the body, very rarely plumose or incrassated. Head with the vertex usually exposed. Eyes reniform. Ocelliform spots rarely absent. Tegmina and wings completely developed, reduced, rudimentary or absent; when present usually semicoriaceous; the costal veins of the wings irregular and much branched, ulnar vein of the wings multiramose, the branches irregular and bifurcated. Sub-genital lamina of male typically quadrate and symmetrical with a pair of slender genital styles. Sub-genital lamina of female modified to form a pair of apposed valves. Cerci variable, but generally flattened and acuminate. Femora generally strongly spined beneath. Tarsi variable. Ootheca chitinous, carried with the suture uppermost. None of the species viviparous.
This is a very well-defined subfamily on account of the valvular structure of the female sub-genital lamina, whilst the males can also be readily distinguished by the symmetry of the sub-genital lamina and by the slender but well-marked styles. I have met with no forms that can be regarded as intermediate between this and other subfamilies of Blattidae. I cannot follow Bolivar in maintaining the subfamily Nocticolinae for the cavernicolous genera Nocticola and Spelaeoblatta; to my mind the undoubted Blattine features of the female sub-genital lamina in these genera over-ride in importance characters that have been called into existence by the cave-haunting habit. Sexual dimorphism is a very marked feature of the Blattinae and some confusion has' resulted from its non-recognition by some authors; there is no doubt that the number of known species of Deropeltis and Pseudoderopeltis will be reduced when we gain more exact knowledge of the two sexes of both genera; several species of Pseudoderopeltis, described from females alone, have been placed in Stylopyga by older authors, so that the synonymy is somewhat tangled. I have separated Stylopyga from the genus Blatta for what I consider a valid reason, viz. the similarity of the two sexes in the former genus, their dissimilarity in the latter. But I am far from satisfied that the species now included in Blatta form a natural group and I am only restrained from further depleting the genus by lack of knowledge concerning the structure of the two sexes in certain species; when this knowledge comes to hand -- as eventually will surely be the case -- the genus can be re-arranged satisfactorily.
