iJIi^LIOGRAPHY. 183 



made great use of the work of Ochsenheimer and Treltschke, 

 but was obliged to depend almost entirely on the synonyms 

 and the Latin diagnoses for the identification of their species, 

 and complained bitterly that the book was not written 

 entirely in Latin. Consequently it is not surprising that some 

 species described by Stephens were wrongly identified by him 

 as belonging to others which are not found in Britain. 



Simultaneously with Stephens' work, appeared Curtis' ''British 

 Entomology" (16 vols. 1823-1840), in which representatives 

 of the principal genera of British Lcpidoptera were figured. 

 Stephens' work, likewise, was not issued without plates, 

 but the first work in which an attempt was made to figure all 

 the known species of British Lcpidoptera was W. Wood's 

 "Index Entomologicus '^ (1833-1839), of which a second 

 edition, with supplement, was edited by Westwood in 1852- 

 1854. This book consists of a series of coloured plates, 

 in which all the larger species are reduced to a uniform 

 size ; and a systematic catalogue of species, including 

 localities, &c., is added. 



About 1840, and in the following years, appeared several 

 editions of Westwood and Humphreys' "British Butterflies and 

 their Transformations," and " British Moths and their Trans- 

 formations." Most of the accidentally-introduced and reputed 

 British species were figured in these works, especially in the 

 former, which was subsequently republished by Westwood in a 

 smaller form, with the practical omission of the reputed species 

 (which were relegated to an Appendix), under the title of " The 

 Butterflies of Great Britain" (1855). 



We have passed over several popular books on British Lcpi- 

 doptera^ but the first serious attempt to describe the whole of 

 the British L.epidoptera with scientific accuracy in a cheap and 

 popular form was made by H. T. Stainton in his " Manual 

 of British Butterflies and Moths" (2 vols.), which was published
