TORYMID^E. 87 



tarsisque pallida flavis ; alae anticae vix fuscescentes, venis pallide 

 fuscescentibus. 



Male. — Black, very slender. Head and thorax very finely punc- 

 tured, somewhat shining. Head rather broader than the thorax. 

 Antenna? verticillate-pilose, longer than the thorax ; intermediate 

 joints long, nearly linear, not petiolated. Thorax long, attenuated 

 hindward. Humeral spots pale yellow, transverse, each occupying a 

 little more than one-fourth of the breadth of the prothorax. Petiole 

 extremely short. Abdomen smooth, shining, nearly linear, rather flat 

 above, a little more than half the length of the thorax. Legs black, 

 long, slender, tibiae at the base and at the tips, fore femora at the tips 

 and tarsi pale yellow. Fore wings very slightly clouded with pale 

 brownish ; veins pale brownish ; ulna about one-fourth of the length 

 of the humerus ; radius and cubitus much shorter than the ulna. 

 Length of the body 1-J — 1£ line. 



It much resembles I. Nepe ; the antennae are a little longer, the 

 hind part of the thorax is more elongated and the wing- veins are 

 paler. The darker fore wings, and more especially the darker wing- 

 veins, distinguish it from I. minor and from I. brevis. It is more 

 slender than I. cornuta, and has shorter antennae than I. 

 longicornis. 



Madeira. 



Fam. TORYMIDiE. 



The occupation of this family, like that of the Eurytomidae, is, with 

 a few exceptions, in galls, and they are especially adapted to destroy 

 their predecessors in the galls, for nearly all the species are provided 

 with a long projecting oviduct, which in some species is of sufficient 

 length to reach the central inhabitant of the largest gall. The general 

 colour of the family is golden green, of which hue there is no trace in 

 the Eurytomidae, but a gradation between the two families appears in 

 Megastigmus : the yellow or luteous body of the latter genus is in 

 M. dorsalis partly overspread with golden green, borrowed from the 

 species of Callimome, with which it is associated in oak-apples. The 

 European genera have been distinguished according to the following 

 synopsis: — 



A. Hind femora with spines, and also serrated or notched. 



a. Hind tibiae much curved. - - Podagrion. 



b. Hind tibiae not curved. - - - Torymus. 



B. Hind femora with spines. 



a. Hind coxae with spines. - - - Monodontomerus. 



b. Hind coxae without spines. - - Diomorus. 



c. Hind femora serrated. - - - Oligosthenus.
