Stephens's NomenclaUire of British Insects. 437 



Mr. Stephens publishes the second part [which, according 

 to the Entomological Magazine, No. iv., he will do " in the 

 autumn "J, I hope he will give a table of the authors he 

 quotes, as his abbreviations are not always intelligible. An 

 index of the genera, and a condensed table of the characters 

 on which the larger divisions of the orders are founded, 

 would also form valuable additions. — H. E. S. Evesham, 

 Worcestershire, July 21. 1833. 



We have announced, in p. 363., that Mr. Curtis is prepar- 

 ing for the press a second edition of his Guide to an Arrange- 

 ment of British Insects, and beg to join H. E. S. in petitioning 

 both Mr. Curtis and Mr. Stephens not to omit supplying to 

 their respective works an index of the genera : the thing is 

 far from useless to many who merit the help of such a leading 

 string : not to be egotistical, to ourselves for one. The fol- 

 lowing remarks, by a correspondent, bear a mutual relation 

 to these two works, and so we may properly introduce them 

 here. We only wish that they were of a kind likely to be 

 more useful and agreeable to our readers in general. — J. D. 



Mr. Curtis, at page 461 . of the last number of his excellent 

 British Entomology, has published, what appears to me, a most 

 unjustifiable attack on Mr. Stephens. He there says, " he" 

 (Mr. Stephens) "has not contented himself with having cor- 

 rected it" (the second edition of his Nomenclature) " from my 

 Guide, and copying column after column from it, but he has 

 actually adopted the style and plan of my work." In what 

 do the copy and correction consist ? It must be in the ar- 

 rangement, for it is the professed object of each work to include 

 all the species named up to the time of publishing it. Let 

 any one compare the arrangement of the first 20 genera of 

 the first order, Coleoptera. In both editions of Stephens's 

 Nomenclature it is exactly the same ; except that Oncoderus 

 (Leiochiton Curt.) is removed, and placed as genus 50, instead 

 of 15, which is its number in the first edition, and which is 

 also the situation, though not the number, which it holds in 

 Curtis's Guide. The following comparison will show that the 

 arrangement of the genera is totally different. The genera, 

 marked by their numbers, stand in the following order in the 

 respective books : — 



* I must inform your readers, that, Mr. Curtis having introduced the 

 Thysanura and Anoplura into his Guide, his genus 10 corresponds with 

 genus 1 in Stephens's Nomenclature.
