EUPITHECIA JASIONEATA. 27 



the great resemblance in the pattern or design on 

 the back of these larvae to that of E. campanulata, 

 which seemed to correspond in every particular but 

 that of size, these being so much smaller. Mr. 

 Harpur-Crewe thought the moth was a nigrescent 

 variety of E. castigata, but I soon saw that though all 

 the lines were present as in that species, yet the paler 

 spot at the anal angle of the superior wings was not 

 present, and that there appeared to be a difference in 

 the cut of the wings, E. castigata having a more pro- 

 duced tip and more convex hind-border than in this 

 moth, which is of a cold grey colour, quite different 

 from the brownish-grey of E. castigata. 



The larva is about or nearly half an inch long, of 

 moderate stoutness, and very rugose, tapering a little 

 anteriorly from the sixth or seventh segment, and pos- 

 teriorly from the tenth. The head is dark brown, 

 marked with darker ; the ground colour of the body 

 varies in different examples from pale whity-brown to 

 brown, lighter or darker, warmer or colder ; beyond 

 the thoracic segments to the ninth inclusive there is 

 on each segment somewhat of a barrel-shaped mark 

 of brown, thickly and strongly marked on each side of 

 the shape with dark brown, or this may be described 

 as a bulbous flask shape, the sides of the bulb thickly 

 defined with dark brown, and a darkish brown dorsal 

 stripe running continuously through all to the anal 

 tip ; on the tenth, eleventh, and twelfth segments the 

 shapes are rudimentary ; a fine dark brown subdorsal 

 line runs close by either side of the dorsal shapes, and 

 bears a dark brown thick mark or blotch close to the 

 widest dark part of the flask shape, sometimes uniting 

 with it, but these do not occur after the ninth seg- 

 ment ; on the side of each segment is an oblique dark 

 [word evidently missing in the MS.] downwards from 

 the front towards the spiracular region ; the belly is 

 whitish cream-colour, with a central dark grey-brown 

 ventral line ; the tubercular warts bear each a fine 

 dark brown central dot on their paler tint, and a short
