78 XANTHIA FERRUGINEA. 



Xanthia FERRUGINEA. 

 Plate LXXXV, fig. 2. 



Though a trifle larger, yet in form and structure 

 this larva closely resembles that of X. gilvago, but 

 with the following exceptions : 



The general colouring is of a browner tint, some- 

 times of an ochreous-brown. 



The series of dark central marks on the back, with 

 their dark wedges, assume together more compact 

 forms of an urn shape, being attenuated behind, so 

 that a constant character appears in the hinder pair of 

 tubercular dots being outside the dark urn shapes. 

 On referring to figures of this species of 1861 and 

 1865, the same characters are apparent, though two 

 of them found under common ash varied much in 

 colour, one being a grey variety, and the other a 

 brighter and more distinctly marked example than any 

 of those on wych-elm. (W. B., E.M.M., IV, 180, 

 January, 1868.)

In April, 1866, the Rev. Joseph Greene kindly sent 

 me a larva he had found concealed in a chink of an 

 ash-trunk ; but as the imago did not appear, its 

 identity was not established till the present season. 



On the 22nd of May, 1867, I had the pleasure to 

 receive another similar larva, detected in a like situa- 

 tion near Leominster by Mr. Thomas Hutchinson, who 

 also generously consigned it to me, enabling me to 

 secure two figures of it in mature growth. 



When full-fed, it spun a rather small cocoon, covered 

 with grains of earth to which a few particles of moss 

 adhered ; and the perfect insect came forth on the 5th 

 of September.
