PEEFACE. 



Vol. I. of Mr. Kirby's " Synonymic Catalogue of Orthoptera " 



was issued in November 1904. Vol. II. now issued has 



occupied just two years in its completion. The collection of 



Orthoptera in the Museum is now in excellent order, although 



all the specimens in every family are not yet fully worked 



out.
