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 tw^o 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 Libellididcr {Y^x2Lgon-'^\t.%),Perlid(E {'i^\oxiQ:-K\t'&),SiaUdcr, 

 Raphidiida: (Snake-flies), Ostnylidce^ Hetnerobida:, ChrysopidcB (Lacewing-flies), 

 Coniopterygida, Panorpidce (.Scorpion-flies), and the Trichoptera: (Caddis-flies). 

 The two other British ^xow.^?,, . Psocidce and Epheineridce (May-flies), I do not 

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

 Blattidcc (Cockroaches), Acrididic (Gra.sshopper and Locusts), and the Acheiida 

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

 and distributed species, are wanted. — Geo. T. Porri i t, Greenfield Hou.se, 

 Iluddersfield, May i8th, 1888.
