less, sleeping apparently for fourteen minutes, and 

 then vibrated the front legs a little, slowly turning the 

 head round, threw out the longest pair of arm-like 

 legs beyond the head, one bent partly over the other 

 like a tired-out athlete enjoying repose in perfect 

 abandonment, for there seemed something very human 

 in the expressively weary attitudes assumed while it 

 again stretched itself with a slight change of position 

 and slept for four minutes more; it then awoke and 

 shook the tail segments, which yet remained compara- 

 tively narrow, when suddenly the exuviae fell away, 

 disclosing the two perfect filaments ; thus at 12.50 

 a.m. was this moult completed, having, from the rup- 

 ture of the skin to this final riddance, occupied one 

 hour and a quarter. ("W.B., 5, 5, 80 ; B.M.M. XVII,

NOTODONTA TRITOPHUS. 



Plate XXXIII, fig. 3. 



On the 27th of July, 1882, I received from Herr 

 Heinrich Disque fifteen eggs of Notodonta tritophus, 

 all laid loose and sent to me in a quill. 



The egg was circular, convexly rounded above and

 smooth without gloss ; its colour was a bluish-greenish- 

 whitish with a central faintly darker spot. Unfortu- 

 nately they all proved infertile. 



However, from the same entomologist I received on 

 the 6th of September two larvae of this species feeding 

 on poplar. On the 8th I noticed that the oldest was 

 laid up on a footing of silken threads crossing each 

 other in all directions waiting to moult, which it did 

 successfully in the evening. On the 11th it was much 

 grown and the smaller larva was laid up to moult. 

 On the 13th the largest larva was one inch six lines 

 long, with a small humplet on the fifth, a hump on 

 each of the sixth, seventh, and eighth segments, and
