LEPIDOPTERA. 



Notes on some of the Genus Eupithecia. 

 By the Rev. H. H. Crewe, M.A. 



Occurrence of a Eupithecia new to Science in Great 



Britain. Eup. fraxinata, Crewe. 

 Since I took up the study of habits, larvae and food plants, 

 &c. of the genus Eupithecia, I have strongly suspected that 

 the typical Continental Eup. innotata, Hb., was entirely 

 distinct from our British species bearing the same name ; 

 though the perfect insects so closely resemble each other 

 that they are as difficult to distinguish as Acronycta psi 

 and tridens, the larvae are so totally dissimilar in habits, ap- 

 pearance, colour and food plant, that I could never beheve 

 they belonged to the same species, and I determined, if pos- 

 sible, to set the matter at rest during the past season. I am 

 happy to say that I have succeeded in doing so, and have 

 much pleasure in announcing to the Entomological world, 

 that our British species is not only entirely distinct from the 

 true Continental Eup. innotata, Hb., but apparently an un- 

 described species entirely new to science. In July last I 

 was able to forward to Professor Zeller, at Meseritz, two full- 

 fed larvas of our British o.s7i-feeding species : these were 

 reared from four eggs, kindly sent me by my friend Mr. ' 

 Greene, who, after much trouble, succeeded in getting two 

 moths to pair in confinement. These moths were reared
