606 Notes in 1887 upon lepidopterous larve, de. 
concealed in this case, although the red margin can be seen. The 
pouch is drawn downwards and inwards behind the fleshy lobes of 
the subspiracular line. The shagreen dots are distinctly shown, 
together with the different shades of green ground colour, above 
and below the subspiracular. The larva represented was a yel- 
lowish green variety. 
Fie. 7, x 4:5. The Ist and 2nd abdominal segments of the 
larva of Stawropus fagi, as seen from the right side. The details 
of structure are only shown in the posterior part of the 2nd 
abdominal segment. The two black marks which are exposed 
when the larva is irritated are distinctly indicated. They resemble 
the single mark of A. taw, being in the form of pouches, which can 
be opened and closed. The lower lip takes the form of a projecting 
flap, which conceals the pouch when it rises, and exposes it when it 
is depressed. The black marks are only exposed, as in the figure, 
after extreme irritation. These marks, doubtless, represent the 
black scars caused by ichneumon stings or wounds, and afford the 
larva protection from parasites by suggesting that it has been 
already attacked. 
Fic. 8, x 24°5. The young larva of Huclidia mi, after having 
crown for a few days in the Ist stage, as seen in the geometriform 
attitude from the left side. The chief bristles and tubercles are 
very distinct. The 9th abdominal segment is clearly marked off 
from the 8th and 10th. The 1st and 2nd claspers are absent, and 
the larva closely resembles a geometer in structure and move- 
ments. 
Fie. 9, x 9. The posterior part of the larva of Ephestia 
kiihmiella, as seen from the right side. The larva had been 
somewhat compressed, so that its dorso-ventral diameter is greater 
than in the normal state. The dark squarish body on the upper 
part of the 5th abdominal segment (the anterior segment figured) 
is the right testis; it is of a brown colour. The chief bristles and 
tubercles are plainly seen. The 9th and 10th abdominal segments 
are very sharply marked off and distinct. 
Fic. 10, x 9. The 5th and 6th abdominal segments of the same 
larva, as seen from above. The larva had been compressed so that 
the diameter from side to side is greater than normal, and the 
testes are separated by an unusual distance. These organs are 
distinctly seen beneath the skin of the 5th abdominal segment, 
just projecting beyond the posterior margin of this segment into 
the 6th abdominal. The dorsal vessel is faintly seen. The chief 
bristles are distinct.
