92 Mr. Clark's Appendix to a Treatise 



The first of these was originally found in Germany, and subsequently in 

 our own country, having been taken June 12th, 1823, in the New Forest in 

 Hampshire, a spot remarkable for its rare treasures in natural history. My 

 esteemed friend Mr. Samouelle, who took it, very kindly lent it to me to 

 draw and describe. Megerle has thought proper to give to it the specific 

 name pictus, " painted." This I somewhat regret, as pictus, " painted," gene- 

 rally has an allusion to gay colours, and this is of a darkish blue. The spe- 

 cific name cwruleus would have been much preferable, as, for an (Estrus, this 

 colour is quite unusual. The name of pictus, when the animal it infests is 

 known, and its place of residence in the larva state ascertained, will probably 

 be changed for a more useful and significant one, and so indeed of the remain- 

 ing species, obliterating my own name likewise.
