Pseudorupilia ruficollis

Cryptocephalus ruficollis, Fabr. The type of this species, described from the Banks' collection, is contained in the British Museum; an examination of the specimen proves it to belong to the Galerucinae, and not to Cryptocephalus at all. Olivier has described the species also, referring it rightly (not wrongly, as Suffrian says) to that of Fabricius. The habitat of the insect is given as St. Helena; some time ago I received from the Museum at Cape Town another specimen, and obtained at the latter place, so that it remains somewhat doubtful whether St. Helena is another locality for the insect : the Cape Town specimen agrees entirely with the type in the Banks' collection, which must find its place in a new genus allied to Rupilia and allied genera. The original specific name of 'ruficollis', altered by Edgar von Harold (1830–1886) to 'erythrodera', can therefore be restored, although the thorax in the type, and in my specimen, is more flavous than rufous. The following is the diagnosis of the genus, and the description of the species

Flavous; the head, antennae, scutellum, the legs, sides of the breast, and the base of the abdominal segments, black; thorax and elytra finely punctured. Length, 23⁄4 lines. …
