M a Fellow of the Linntean Society." This use-* 

 ful little pamphlet was the forerunner of his 

 " Lepidoptera Rritannica," a new treatise on 

 British Lepidoptera, or Butterflies and Moths, in 

 Latin, with occasional observations in English ; 

 the first part of this treatise was published in 

 1803: a second part appeared in 1809; a third 

 in 1811 ; and a fourth, completing the work, in 

 1828.* It contains 609 closely-printed octavo 

 pages, and 36 of preface ; to which are appended 

 above 200 similar pages, entitled " Miscellanea 

 " Naturalia." The treatise describes above 1450 

 Lepidoptera, and concludes with a complete 

 index of all their genera and species.f About 

 the year 1806, Mr. Haworth took a leading part 

 in the formation of the Entomological Society 

 of London, of which he became the President. 

 The operations of the Society, after a few years, 

 were discontinued for want of funds, but not 



* An Article on this concluding part, furnished anonymously by the 

 Rev. W. T. Bree, to London's Magazine of Natural History, (vol. 1, 

 p. 348) explains the cause of the extraordinary delay which took place in 

 its publication, after an interval of twenty-five years from the period of 

 the first commencement of the work. 



f This refers to the genera of LepidopteroUs insects, as at that time 

 established, viz. in 1803. It reflects no discredit on Mr. Haworth as a 

 naturalist, that he did not construct and publish many more genera in the 

 first instance j he would have done so, but for the urgent solicitations of 

 his friends to the contrary ; and even in those which he did publish, he 

 gave great offence to many Entomologists, who deemed these innovations 

 in the nomenclature, unnecessary incumbrances to the science. Time 

 has, however, proved that Mr. Haworth was right in his original design, 

 but the Entomological world was not then prepared to admit his doctrine.
