This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1871 Excerpt: ...the contraction of the abdomen at the base; it occurs in North Africa; and L. atra of Hindostan, L. Aruina of Aru, and L. antiqua of New Caledonia belong to it. In all these species there is no trace of a metallic hue, and thus no blending with the general character of the other Chalcidte; and in North America this distinction is attained also by L. Shuckardi and Canadensis; but in L. subnotata the metallic hue appears on the front. Towards the equator this lustre is general on the body in L. Mexicana, Cayennensis, Tapayana, speifera and Egaia; it does not occur in L. Santarema, but in this the black ground hue of the European and Arabian species is replaced by red. The Chilian L. Hopei is another type, of which the red antennae are a peculiar character. There is another form of the genus in L. leucotelus; it has no metallic hue nor pale markings, and its wings are black. Leucospis is parasitic on aculeate Hymenoptera, but has not followed its prey northward so far as the latter extends, and being of comparatively rare occurrence it has only a slight control over its victims. The genus Polistomorpha is distinguished by the elongated face, by the basal contraction of the abdomen, and by the less incrassated hind femora. In the genus Marres the head is deeply excavated. L. Japonica. Fcem. Nigra; antennae apice rufescentes, articulo 1o flavo apice supra nigro; prothorax fascia postica abbreviata flava; abdomen maculis duabus basalibus quadratis fasciaque subapicali flavis; oviductus scutelli apicem attingens; coxae postica e flavo unistrigatae; femora postica octodentata, fascia exteriore basali arcuata flava; tarsi rufescentes; ate nigricantes. Female. Black, very thickly and minutely punctured, with short cinereous pubescence. Antennae stout, subclavate, dul...
