Habitat in Africa tropicali ? In Mus. Bristol Philos. Institution. The singular, almost semicircularly elevated carina along themiddle of the mesonotum, at once distinguishes this insect from allother Phasmidse. It appears to be congeneric with the specieslast above described, although destitute of any lateral the development of the sexual apparatus, which is nearlysimilar to that of D. serricollis, I consider the specimen not tobe in an immature state. h. 51 PLATE LXII. DESCRIPTIONS OF SOME NEW SPECIES OF SOOTHSAYERS.(MANTIDjE.) PHYLLOCRANIA INSIGNIS, Westw. (Plate 62, fig. 1.)P. luteo-fuscn, tegminibus olivaceo-fuscis, basi, vittaque obliqua media albidis, alarum angulo apicali producto, hoc areaque anali fuscis reliqua parte alarum fulvescente fusco irrorata, foliolis prothoracis et pedum posticorum albido et olivaceo corp. (cornu capitis incluso) unc. 2^.Habitat in Sierra Leone. In Mus. Britl. et D. Hope. This insect appears to be specifically distinct from Ph. paradoxa,of Burmeister*; it agrees, however, with it in its remarkablestructural peculiarities, namely, the singular, elongated, narrow,leaf-like appendage of the head, the dilated sides of the prothorax,and the leaflets of the four hind femora and tibiae. Mantis Diana,of Stoll (fig. 100), and the Empusse, agree with Phyllocrania in theproduced head, but the latter have pectinated ante
