In 1770, the following year, John Eeinhold Forstei, published at Warring- 

 ton, a "Catalogue of British Insects." This was a mere catalogue of Latin 

 names, but the most extensive yet made, amounting to a thousand species. 



In 1772, "The Naturalist and Traveller's Companion," by Dr. Lettsom, 

 was published at London, giving directions how to collect and preserve all 

 sorts of natural productions, and is a very useful book especially to beginners. 



We now come to a year fertile in the produce of entomological works, for 

 in 1773, Yeats, published at London, his "Institutions of Entomology, 

 being a translation of 1^^336^' ' Ordines et Genera Insectorum : " or 

 systematic arrangement of insects, collated with the different systems of 

 Geoffroy, Schaffer, and Scopoli." This is an excellent publication for its 

 time. In it, Yeats writes : The division of the butterflies into families, from 

 the circumstances chosen by Linnaeus, seems liable to many objections : the 

 family of the Plebeii, in particular, is very inaccurate, and contains insects 

 very different from one another. Scopoli and Geoffroy have divided this 

 genus into different families from the number of their feet ; a method which 

 cannot easily be pursued in cabinets where exotic butterflies are admitted, 

 these parts being generally destroyed before such insects reach Europe. The 

 other circumstances from which Geoffroy has taken his divisions into families, 

 viz., the form of the caterpillars, is totally impracticable, except where the 

 collector admits no other butterflies into his cabinet, but such as he himself 

 possessed in the caterpillar state. Geoffroy has, besides changing the orders 

 of the Linnaean system, formed from the different families of Linnsean genera 

 many new genera, some of them very judiciously, others perhaps without 

 sufficient grounds. Schseffer, in his f Elementa Entomologiae/ printed at 

 Ratisbon, in 1776, has followed Geoffrey with very few and inconsiderable 

 variations. I should have been glad to have given some account of the 

 system of Poda, a Jesuit, a work much praised by Scopoli, but have not
