The present paper is necessarily in great part a compilation, but 

 sufficient new material is presented to render it' worthy of appearing as a 

 whole, so that Kirby's species may be at once determined without the 

 necessity of consulting scattered publications. 



A few words are necessary to a correct understanding of the paper. 

 The species named by Kirby are in small capitals. Should names in their 

 entirety remam valid, no remarks are made, as in i, i6, &c. Should the 



generic name only be changed, the species is quoted as " is a ," as 



in 25, 28, 37, &c. Should the specific name be changed, the species is 

 quoted as in 3, 5:c., and the true name is in smaU capitals also. In some 

 instances, Kirby's species not having been identified, the species have 

 received more recent names and are well known ; in this case the latter 

 name (being a synonvm) is quoted in italics, as in 58 and 59, so that 

 those having the Kirbyan species under the more recent names may 

 change them.
