STAUKOPUS FAGI. 65 



traversed to their summits by a similar brownish- 

 ochreous indication of a subdorsal stripe ; the side of 

 the humps as far as the spiracular region was a deep 

 crimson-brown ; this was bounded below by a black 

 wavy line, beginning on the seventh segment and con- 

 tinuing along just above each spiracle as far as that 

 on the tenth segment, whence it slants down the side 

 of the ventral proleg. This black line was well-con- 

 trasted immediately beneath by a paler brownish- 

 ochreous colour, but this was soon obscured a little 

 below by darkish brown freckles closely aggregated. 

 The last three segments, which were generally more or 

 less elevated, were of a dark crimson-brown colour, 

 showing but a faint trace of the dorsal stripe or of 

 the subdorsal ; these could, however, just be traced 

 from the darker lines of freckles which mapped out 

 the details. The dilated margin was pale ochreous, 

 and spotted with a row of small, raised, black dots at 

 the very edge. The spiracles were oval, greyish- 

 ochreous outlined with black ; the anterior legs were 

 dark brownish-red, shining and delicately pubescent ; 

 the anal filaments dark purplish-brown, growing 

 darker brown towards the tips ; the belly was slightly 

 paler than the back, and of similar colouring ; the tips 

 of the ventral prolegs dark crimson-brown. (W. B., 

 Note Book III, 158.) 



On the 28th June, 1877, I received from the Rev. 

 Bernard Smith, of Marlow, two eggs of Stauropus fagi 

 laid on a piece of canvas by a dark variety of the 

 female. 



The egg was of a good size, circular, flattened a little 

 beneath, and with a slight central depression above, 

 the surface glistening as a pearl. Viewed through a 

 strong lens it was seen to be most minutely pitted ; 

 it was cream-coloured, with a brown central spot in 

 the depression above. On the morning of the 30th 

 they were of a mottled appearance, reminding me of a 

 full-ripe greengage plum, some parts like a pinkish 

 bloom, another part at the side like an internal blotch
