Size (mm):
Genus & species Chrysis ruddii Shuckart, 1837
Species group ignita
Original combination Chrysis ruddii Shuckard, 1837
Type series Syntypi (Mus.: ?)
Original description Head, first and second joints of the antennae, and legs, excepting the tarsi, of a rich green or blue, more or less splashed with gold; the collar and scutellum more or less cupreus; the tarsi and flagellum of the antennae black: the abdomen of a rich carmine pink, opaque, and occasionally with a golden glow, very densely and minutely punctured with a slight longitudinal carina along the centre, becoming obsolete on the third segment: the terminal teeth approximating to Var. 2 of Chry. ignita. Length 4-5 lines.

It will be expected that I should give my reasons for considering this, which has the same distribution of colour as all the varieties of the C. ignita, a distinct species, and why I treat those merely as varieties. I may refer to my observations under that species for some reasons; others are, the minutely punctured abdomen, its invariably carmine pink colour, and the coppery refulgence, always in some degree present, of the prothorax and scutellum. I have much pleasure in dedicating this elegant species to my kind friend the Rev. G.T. Rudd, he having first attracted my attention to it by some splendid specimens from the New Forest. His claims upon entomologists for his discoveries in the obscure families of the Staphylinidae and of the Ichneumones adsciti, justify also a departure from the rigid rules of scientific nomenclature, which are but too frequently sinned against to record merely a private friendship. This species has occurred near London, and in the New Forest, Hampshire.
