 description qf every British Butterfly, Caterpillar, and Chrysa- 

 lis, has, from theextreme difficulty itf obtaining that desideratum, 

 occasioned unavoidable delay : in this department, however, she 

 has been most materially assisted by the kindness of the IU:o. 

 ffilliam Kirby, whose knowleilge of Entomology is equalled only 

 by his liberality in imparting it. From Ochsenheimcr's elaborate 

 work (Schmettcrlinge vou Europa) he has added the descriptions 

 of many Caterpillars and Chrysulies to those in Haworlh, To 

 him also she is particularly indebted for the descriptions of many 

 of the rarer Butterflies, which his superior informatimi and a 

 r^erencc to the works of foreign authors in his valuable lil/rary, 

 enabled him to supjity. For all his Judicious corrections and for 

 his superintendence of this little work, she begs to offer her 

 grateful and sincere ucknmvlcdgments.
