OF THE LARVA OF PYGÆRA BUCEPHALA. 191 
DESCRIPTION OF THE PLATES. 
Tan. XXXIV. ann XXXV. 
In Tab. XX XIV. the insect is supposed to have been cut open down the side, the internal organs to 
have been removed, and then the skin to have been flattened. The muscles of one side only are 
represented. 
In the first figure of Tab. XXXV. the muscles figured in the former plate are supposed to have been 
cut away, 50 as to expose many others which would at first have been partly concealed. 
In the second figure of Tab. XX XV. the remainder of the cutaneous muscles are represented. 
Of course the muscles represented in the last two figures would have partly appeared between those 
figured in Tab. XXXIV., but I thought it would cause confusion if they were inserted more than once. 
All three figures refer to the three thoracic and first four abdominal segments, and are magnified 
about 8 times.
