152 ME. B. m'lachla-N on the neueopteea or 



for other orders formed the subjects of scattered papers by various 

 writers. The Neuroptera were undertaken by Hagen ; and in 

 1865, in vol. ii. of the * Entomologists' Monthly Magazine,' ap- 

 peared his ' Neuroptera of Madeira ' (pp. 8-11, 25-28, 59-62, and 

 75-81), in which all the information at that time possessed was 

 embodied. Hagen there notices or describes 26 species, of which 

 only very few had been previously recorded as inhabiting the 

 island. This is the groundwork of our knowledge of the Neuro- 

 ptera of Madeira. [The part relating to the Trichoptera was also 

 published almost simultaneously in the ' Stettiner entomologische 

 Zeitung,' vol. xxvi. pp. 217-222.] 



Beyond the necessary references to species in monographic 

 works on special groups, nothing has since appeared. 



In November and December 1880 my friend the Eev. A. E. 

 Eaton, M.A., visited both Madeira and the Canary Islands, the 

 first time that either had been explored by an experienced Neuro- 

 pterist. Mr. Eaton was happily not driven thence by considera- 

 tions of health ; yet from other causes his movements were not 

 altogether untrammelled, and the time of year was most unfavour- 

 able. His stay in Madeira was only from the 17th to the 30th of 

 November (1880) ; nevertheless in those few days he collected 

 20 species, several of which were previously unknown. All the 

 materials he generously placed at my disposal ; and they formed 

 the inducing cause of the production of the present paper. Let 

 us hope that he, or some other equally experienced Neuropterist, 

 may be able to explore the islands in the favourable season ! 



Canaet Islands. 



If our information be yet meagre for Madeira, it is far more 

 so for the Canary Islands. Madeira is the sanatorium for the 

 world. The Canary Islands are now forbidden to acknowledged 

 invalids y5'0«t any cause, although formerly the restrictions would 

 not appear to have been so severe ; for Heer, Hartung, Wollaston, 

 and probably others, all in indifferent health, explored the islands. 

 So also did the brothers Crotch and others, who could not be 

 considered invalids ; but almost the whole of these explorers con- 

 fined their attention mainly to Coleoptera. I have only been able 

 to compile the following references, but have reason to believe 

 that both material and information are contained in Erench 

 museums and publications that I have not been able to consult.
