The NATURALIST.

It being the wish of the Editors to make the journal the recognised organ for 

 information concerning the natural history of the North of England, they hope 

 to rely on Naturahsts keeping them supplied with articles and short notes 

 from time to time. >ocx 



Communications should be written on one side of the paper only, and 

 should be sent as soon after the commencement of the month as possible. 



Short Notes of important occurrences will be received up to the 20th of 

 the month, and specially urgent ones even later.

Yorkshire Neuroptera and Orthoptera.— I am anxious during the 

 present and several future seasons to work up the Neuroptera and Orthoptera of 

 our county as much as possible, with a view to publishing a list of species, with 

 their localities, etc., and shall be very grateful to all entomologists (or other 

 naturalists) who, when out collecting their own particular groups of objects, will 

 kindly kill and pin (of course they need not trouble to set them) one or two or 

 three specimens of any species they may come across, and send them to me at the 

 end of the season — or oftener if it be not too much trouble. The families in the 

 Neuroptera wanted are the Libelhdidcp {T)xzgon-?aQs),Ferlid(s {Sion&-?ats)^S2alida, 

 Raphidiida (Snake-flies), Osmylidce^ Hemerobidce^ Chrysspidez (Lacewing-flies), 

 ConiopterygPsxcB^ Panorpidce (Scorpion-flies), and the Ti'ichopterce (Caddis-flies). 

 The two other British groups, Psocidce and Ephemeridce (May-flies), I do not 

 propose to touch at present. The Orthoptera include the ForficulidiC (Earwigs), 

 BlattidcE (Cockroaches), AcrididcB (Grasshopper and Locusts), and the AchetidcB 

 (Crickets), all of which, with the exception of the several universally abundant 

 and distributed species, are wanted. — Geo. T. Porritt, Greenfield House, 

 Huddersfield, May i8th, 1887.
