scriptions, a principal object will be to render the work generally 

 useful and interesting to the British naturalist. 



The parts will follow each other with every degree of expedition 

 consistent with the preservation of the style of publication in which 

 the work has been commenced. Those preparatory arrangements 

 which are inseparable from every undertaking of this nature have 

 in some measure retarded the first part, but the publishers are en- 

 abled to engage, with every prospect of success, a regular conti- 

 nuation of the work : accordingly they announce the appearance of 

 the second part early in July next, of the third, at the commence- 

 ment of the ensuing year, and of the remaining parts at intervals 

 of six months. According to this plan, the whole will be completed 

 within three years from the commencement. 



Lepidoptera Britannica ; sistens Digestionem novam Insectorum Le- 

 pidopterorum quce in Magna Britannia reperiuntur, larvarum pa- 

 bulo, temporeque pascendi ; expansione alarum ; mensibusque vo- 

 landi ; synonymis atque locis observationibusque variis. Autore 

 A. H. Haworth, Linn. Soc. Lond. Soc, fyc. fyc. 



We congratulate the admirers of British Entomology on the long 

 expected appearance of Part IV. of Mr. Haworth's Lepidoptera 

 Britannica, which is at last completed. 



This comprehensive and valuable work consists of 609 closely 

 printed octavo pages, and 36 of Preface, and has been divided into 

 four parts ; to the first of which was appended above 200 similar 

 pages, called Miscellanea Naturalia. 



Complete new-wrought descriptions and synonymies of all the 

 known British Lepidoptera are given throughout in Latin ; together 

 with occasional observations in English, respecting their pecu- 

 liarities, size, food, times and places of appearance, &c. 



The First Part, which was published by the author in 1803, con- 

 tains the Papilionidce, Sphingidce, and Bombycidcc. After this, the 

 work languished for want of encouragement, till the beginning of 

 1809, when the Second Part was published. It contains the He- 

 piali, Lithosice, Palcarice, Noctuadce, Phalcenadce, &c. 



The Third Part appeared in 1811. It contains the Pyralid<z, 

 Tortricidce, &c. And the Fourth Part, which has just been pub- 

 lished, completes the arduous and useful undertaking of its inde- 

 fatigable author. It contains the Tineadce, &c. ; and concludes the 

 work with a complete Index of all the genera and species of Lepi- 

 doptera described ; about 1450 in number.
