This genus contains species of A inch and more, whilst the sinallost 

 species are still more than 3 lines in size, so that it may be considert.il 

 gigantic in this family of dwarfs. In Europe species of Zefuv.^ 

 found in the southern regions alone, principally in Italy. To the extrica- 

 tion of the synonomy ILLIGKR, KLUG, and lately AVi-.srwoon. have contri- 

 buted : see the monograph of the last-named author, i)tomol. Mti>ia*. n.

Family XXI. Ichneumonides. Wings four, veined, the anterior 

 always furnished with complete cells. Maxillary palps distinct, 

 elongate. Antennae mostly setaceous or filiform, lon^. with numer- 

 ous joints. Body elongate, slender. Ovipositor straight, often 

 exsert, bivalved, including a borer of three seta\ 



Slip-wasps, Ichneumons. We unite in this family the Ic/nieu- 

 manides and Evaniales of the systematic entomologists of recent 

 times. Of many species the economy is yet unknown, yet of all 

 whose mode of life has been observed the larva? are found in other 

 insects, and nearly always in the lurvre of these. They are especially 

 caterpillars, the larvae of Lepidoptera, in which Ichneumon- 

 their eggs; the larvae of JBvania are parasites of the genus Bhttta, 

 and probably live, according to an ol^ervation of MAO LEAY (related 

 by WESTWOOD, Introd. to mod. Chissif. of Ins. i. p. 22) in the 

 membrane of their eggs.
