A Monograph Of The British Phytophagous Hymenoptera Vol 2

Excerpt from A Monograph of the British Phytophagous Hymenoptera, Vol. 2: Tenthredo, Sirex and Cynips, Linne The present volume is devoted to the Nematina, possibly the most difficult group in the entire family; and, as will be seen, it contains the largest genus, namely, Nematus. The number of species recorded compares very favorably with what is known elsewhere but I am persuaded that very many species have yet to be discovered in Britain, especially in the North, where they appear to be most numerous Might I therefore express the hope that some of our Entomologists would pay attention to these interesting insects, and thus enable me to describe many additional species in the concluding volume of this work. Especially is it desirable that they be reared from the larvae; for in Nematus many species are excessively alike in the perfect state, although quite distinct as larvae. Thus, if they be reared from the larvae, not only will our knowledge of their habits be increased, but the specific distinctions will be more clearly defined. I regret that I have not been able to figure more of the larvae, but living as I do in a large city, both the getting and the rearing of the larvae is a work of difficulty.
