BOOKS ON NEUROPTERA AND TRICHOPTERA. 



By G. T. PORRITT, F.L.S., F.E.S. 



|r. Tutt, by inadvertently misquoting my letter {ante, 

 p. 6i), fails to give the meaning I intended to 

 convey. I did not say, " There is no book on the 

 Neuroptera."^ What I wrote was, " There is no 

 book on the British Dragonflies nor on the British Neurop- 

 TERA as a whole." There are several monographs on separate 

 groups, and the works by McLachlan, The TricJioptera of the 

 European Fauna, and Eaton's Monograph of Recent Epheine- 

 ridoB, the latter forming Vol. III. of the Transactions of the 

 Linnean Society of London (Zoology, 2nd Series), are beyond 

 all praise. On various groups, too, McLachlan's Monograph 

 of the British Neiiroptera-Planipennia, including the Sia- 

 lidcB, RaphidiidcB, OsmylidcB, Hemerobidce, ChrysopidcB, Panor- 

 pid(B, etc., published in Part II. of the Transactions of the 

 Entomological Society of London for 1868 is most useful ; and 

 so are Dr. Hagen's Synopsis of the British Psocidcs, Synopsis 

 of the British Dragonflies, Synopsis of the British Planipennia, 

 and Synopsis of the British EpJienieridcE, published in the 

 Entomologisfs Annmls for 1861, 1857, 1858, and 1863 respec- 

 tively. Mr. McLachlan's Trichoptcra Briiannica, published 

 in Transactions of the Entomological Society, 1865, will be found 

 very useful in the absence of the same author's more recent 

 and bigger work. There is no separate monograph on the 

 British Perlidcu, and this is much needed. But perhaps what 



' Mr. Porritt wrote " On the Dragonflies," as he says. The error was decidedly 

 mine. —Ed.
