PHVCITID.E—ALISPA. 27 



pulsating vessel forms the dorsal stripe ; ou each side and 

 upon each segment, between the dorsal stripe and the 

 spiracular region, is a large rust-coloured max'k — in some 

 specimens a double mark, it being divided transversely in 

 the middle — there is also a less conspicuous series of rust- 

 coloured marks in the spiracular region ; dorsal plate 

 polished, of the ground colour, with a smoky mark divided 

 by the dorsal stripe, in the middle, behind ; on each side of 

 this plate is a rather large, intensely black spot ; anal plate 

 darker than the ground colour; spiracles minute, black; 

 ventral surface pale green. (G. T. Porritt.) 



August to October, in the berries of spindle (Hi'Ojn/nivs 

 niropiii>i), hollowing them completely out, moving when 

 necessary to a fresh berry, sometimes uniting two or more 

 together, leaving a small round hole through which the frass 

 is extruded. 



Pupa apparently undescribed ; in a strong papery silken 

 cocoon in the earth or in rotten wood. Usuallj' the larva 

 remains unchanged through the winter in this cocoon, and 

 assumes the pupa state in the spring or early summer ; but 

 in hot seasons some individuals pnpate at once, and produce 

 the partial second generation. 



This moth is said to hide among its food-plant, and very 

 rarely to be captured in the day, but I have no personal 

 knowledge of it. In 1875 the late Mr. W. Machin recorded 

 it near Hampstead sitting on the trunks of chestnut-trees. 

 It doubtless flies at night, but even this seems scarcely to 

 have been observed. Almost all the specimens in our collec- 

 tions have been reared from gathered berries. Exceedingly 

 local and uncertain, but it has been found — sometimes in 

 plenty, in the larva state — in Middlesex, Surrey, Kent, 

 Herts, and recently by Mrs. Bazett in Oxfordshire ; and 

 is recorded also in Devon, Gloucestershire and Hereford- 

 shire. This apparently is the extent of its range in these
