HawortEs Lepidoptera Britannica, 349 



ago. In doing this, he has judged, we think, wisely; for, 

 otherwise, the work would not have been all of a piece, and 

 would, perhaps, have brought to our recollection the opening 

 lines of Horace's Art of Poetry^ — 



" Humano capiti cervicem pictor equinam 

 Jungere si velit," &c. 



We rejoice, however, to learn, by the postscript, that Mr. 

 Haworth contemplates a new edition and entire revision of 

 the whole. The science of entomology has undergone great 

 alterations as to its nomenclature, divisions of genera, &c., 

 since the earlier parts were printed. It has become much 

 more popular, and more extensively studied. The original 

 work, too, though not free from errors and omissions (as the 

 author candidly acknowledges), is yet invaluable to the British 

 lepidopterist, and has become exceedingly scarce. The im- 

 pression was a small one, and the earlier parts have long been 

 out of print. The new discoveries also made in this depart- 

 ment of natural history, since the year 1803, are numerous, 

 and highly interesting. In short, a revised edition of the 

 work, or a new work on a similar plan, is required by the 

 present more advanced state of the science. No one (we 

 speak advisedly in saying this) is better qualified for such 

 an undertaking than Mr. Haworth, who, in addition to long 

 practical experience, possesses an extensive and profound 

 knowledge of entomology, a most accurate and discriminating 

 eye, and a dexterous facility in describing that most beautiful, 

 order of insects of which he treats. We sincerely hope he 

 will put his intended plan in execution, and without delay. 

 There can be little doubt but that such a work as he contem- 

 plates would meet with more encouragement from the public 

 of the present day, than fell to the lot of Lepidoptera Britan- 

 nica in 1803. It is almost unnecessary to add that, as vast 

 alterations in the nomenclature have taken place since that 

 period, there should be in the new work a constant reference 

 to the old. The glossary, also, of entomological terms, 

 together with a set of explanatory figures, which, though 

 never executed, formed a part of the original design, should 

 by no means be omitted. 



The present part contains a description of ten genera of 

 minute moths, viz. Erminea, Capillaria, Dasycerus, Chelaria, 

 Gracillaria, Porrectaria, Ypsolophus, Recurvaria, Incurvaria, 

 and Tinea; the whole comprehending about 247 species. It 

 is unnecessary to say more on this concluding part, as no 

 doubt it will be in the hands of every entomologist who pos- 

 sesses or can procure the preceding volumes.
