appear as large glossy intensely black spots, four 

 round ones on the dorsal area of each segment, and a 

 row of triangular ones above the spiracular stripe. 



The ventral surface and prolegs are of the same 

 colour as the dorsal area ; the legs highly polished and 

 black; below the spiracular stripe, but adjoining it, is 

 a series of oval black spots, one on each segment ; yet 

 lower is a similar series of spots, but each placed a 

 little further behind than the one above it; and still 

 below these again, indeed, just at the top of each leg 

 and proleg, is another similar but smaller spot ; whilst 

 those segments which have no legs nor prolegs (the 

 fifth, sixth, eleventh and twelfth) have each three 

 similar transverse spots. 



Shortly before spinning up the ground colour 

 changes to a straw-colour ; then, in the two leaves 

 spun together in which the larva seems to live when 

 not feeding, a loose cocoon is formed. 



The pupa is about five-eighths of an inch long, 

 rather slender, and attenuated towards the point; the 

 wing-cases are long, and, as are also the eye-sheaths, 

 well defined ; there is a sharply defined ridge along the 

 thorax. The colour of the thorax, wing-cases, and 

 eye-sheaths is dark chocolate-brown, the under-side 

 of the abdomen paler brown, the divisions yellow. 



The imagos emerged at the end of June and in 

 July. (George T. Porritt, 7th February, 1880; 

 E.M.M., March, 1880, XVI, 228.) 



SCOPULA PRUNALIS.

During October, 1876, Mr. William R. Jeffrey 

 drew my attention to some very juvenile larvse, such 

 as he had before found at that time of year on 

 Galeobdolon, Lamium, and a few other plants, but 

 I was unable to name the larvee then, or to find any 

 description giving a clue to their identity, or to rear
