LA RENTID.L^.—EMMELESIA. 243 



Mr. Buckler that, the lar\'a having been previously much 

 more plain, it is at this time that the brilliant adult colour 

 and markings are as.sumed, and that this so admirably 

 assimilates to the leaves and stems of the little plant that, 

 even when a larva is known to be on a shoot, its detection is 

 difficult. 



Pt'PA of ordinary form, bright yellowish-green, having a 

 broad stripe of crimson down the middle of the back of the 

 abdomen, sucfsrestive of the larval design ; surface rather 

 glossy. In a compact little cocoon in light soil. 



The winter is passed in this state. 



The moth hides usually, during the earlier portion of the 

 day, among heather; in the late afternoon it flies gently 

 about and continues on the wing till dusk. It is a very local 

 species, usually occurring in mountain districts. One or 

 two reported captures in the South of England proved to be 

 erroneous, but it is found in several localities in Cumberland, 

 and probably in other hill districts of the Noi'th of England. 

 Mr. Robson reports its occurrence, many years ago, in 

 Durham. In Wales two specimens were taken in the j^ear 

 1873by Mr. Jenner-Fust, at Dolgelly, Merionethshire; it has 

 been taken at Llantrissant, in Glamorganshire by Mr. Evan 

 John ; and it is reasonable to conclude that, if investigated, 

 that country of mountains would furnish many othei' locali- 

 ties. In Scotland it is widely distributed, and in mountain 

 districts often abundant, as in Perthshire and Inverness, 

 Moray, Dumbartonshire, Argyleshire, and elsewhere in the 

 Clyde district : also in the Hebrides, Orkneys, and Shetland 

 Isles. In Ireland it is reported from Kerry and Cork, J 

 have myself taken it in Galway, in a limestone district which 

 was iwl mountainous, and Mr. D. C. Campbell took examples, 

 which I have seen, in Derry. 



Abroad it is found in Central Europe, the greater portion 

 of Northern Europe, and the North of Italy.
