280 THE ENTOMOLOGIST. 



pl. 1, figs. 4, 7, 9 represent the white ermine, 5 and 6, mendica ; 

 Reaumur first describes the former both sexes, and then says he 

 has also obtained from identical larvae those other forms, figs. 5 

 and 6. 



(ix) De Geer, 1, pp. 183-4, ff. 7, 8 (1752-1778). Knows both 

 species in each sex, but confuses them as one species. He 

 figures (pl. xi. fig. 7) a female lubricipeda, and (fig. 8) a male

(i) Geoffrey, Paris Hist. Ins. p. 118, No. 21. Describes men- 

 thastri, but confuses mendica with it as a variety, following the 

 lead of Reaumur. This Geoffrey was Etienne Louis, who pub- 

 lished ' Histoire Abregee des Insectes qui se trouvent aux Envi- 

 rons de Paris ' (1762). 



(ii) Fourcroy, ' Entomologia Parisiensis.' In this work of 

 Geoffrey, edited or published by Fourcroy after his death, ii. 

 p. 263, No. 21 (1785), there is a moth described, P. lubricipeda.
