the Solidago, for he states that the food of the Caterpillar is 

 the Vaccinmm Vitis Idcsa (pi. 662.), but it may probably feed 

 on other plants ; however this may be, it is undoubtedly con- 

 fined to northern and mountainous countries, and the disco- 

 very of it in England has added a very distinct species to this 

 fine and extensive Order. Mr. F. Walker in his visit to 

 Norway last year, captured several specimens in the middle of 

 September; they had settled on a wall at Happar, near Torneo. 

 This induced me to search the Linnaean cabinet, where I de- 

 tected an unnamed specimen, apparently confounded with 

 'N. Polyodon. 



For the male figured I am indebted to Mr. S. Carter, of 

 Manchester, who informs me that " two specimens were taken 

 for the first time nine or ten years since at a place called the 

 Brushes, about two miles beyond Stayley Bridge ; they were 

 found on a rugged stone wall on the south side of a brook 

 that runs between two mountains : since that period only four 

 specimens had been taken until this year (1837), when they 

 made their appearance from the 20th of August to the 16th of 

 September ; they were principally taken about six o'clock in 

 the morning, and none later than ten o'clock." 



The angulated abdomen and the attitude of the wings in 

 repose, induce me to adopt Hiibner's generic name, and to 

 separate this moth from Xylina (fol. 256.), to which it is other- 

 wise nearly related, and I have the less hesitation in doing so 

 as it has never been described in any English work. I have 

 added a figure of the larva from Hiibner, and I take this op- 

 portunity of correcting an erroneous opinion that the moth 

 before us is a Ciicullia, with which name it was forwarded to 

 me, and as such it is also recorded in the Entomological Ma- 

 gazine. 



For specimens of the beautiful Purple Saxifrage, Saxifraga 

 oppositifolia., I am indebted to the Rev. T. Howson, who for- 

 warded them last May from the Upper Limestone of Penigent, 

 in Yorkshire.
