EXPLANATION OF PLATE XXVIII. 
From Photograph by A. E. Tonge. 
Winter cocoons of Marasmarcha. 
1. Cocoons, showing contained larvee of Marasmarcha lunedactylus, 
x 26 diameters. The cocoons are between a dead leaf (background) 
and a thin glass (in front); the contained larve are consequently 
very easily seen, the silk against the glass being very thin. 
2. Same as No. 1, except that two empty egg-shells appear in the 
field, permitting a comparison of the size of the egg and of the 
hibernating larva (x 26). 
3. Three cocoons on glass (background), x 26. The silk on the 
free surface is dense enough to hide the larva; these give some 
measure of the amount of silk spun. 
4. A cocoon found in sand, all the grains of sand (except one) 
removed, mounted in Farrant’s medium, x 26, The medium renders 
much of the silk transparent, and invisible in the photograph. 
5. Cocoons of Marasmarcha tuttidactyla, between glass (in front) 
and paper (background), with three empty egg-shells on black 
background. N,B,—This is only magnified x 10 diameters.
