Male and female beetles. Fig. 2. — The chestnut telephone-pole 
borer: Young larvae, dorsal and lateral views. Fig. 3. — Damage 
to an untreated chestnut telegraph pole near surface of ground by

II. Work of the chestnut telephone-pole borer. Fig. 1. — Gallery of the 
chestnut telephone-pole borer showing pupal chamber with the 
entrance plugged with excelsior-like wood fibers; work near base 
of pole below ground. Fig. 2. — Mines of the chestnut telephone- 
pole borer near surface of ground 4 
III. All castes of Leucotermes virginicus in heartwood of a maple tree 
infested by Parandra brunnea 22 
IV. Book destroyed by termites 22 
V. Pine barn sill cut into ribbons by termites 22 
VI. Living, stag-headed chestnut tree infested for entire length by ter- 
mites; the insects entered the tree at the base through a lightning 
scar and honeycombed the heartwood 22 
VII. Views of sheds constructed by Leucotermes virginicus to cover up 
galleries exposed on cross sections of logs sawn from an infested 
maple tree 26 
VIII. Lateral views of fully developed nymphs of the first and second 
forms, and lateral and dorsal views of neoteinic kings of Leuco- 
termes flavipes 30 
IX. The evolution of the soldiers of Leucotermes virginicus and L. flavipes 
from the large-headed worker-like larvae, showing the changes at 
the molts 34 
X. Quiescent stages during the final molt of nymphs of the first form of 
Leucotermes flavipes and the active molted nymph with wings 
unfolding, lateral and dorsal views 38 
XI. Quiescent stages during the final molt of nymphs of the second form 
of Leucotermes flavipes and the pigmented neoteinic king, lateral 
and dorsal views „ . 38 
XII. Fig. 1. — "Royal cells," in which true queens of Leucotermes flavipes 
were found. Fig. 2. — Royal chamber excavated in solid chestnut 
wood, in which 40 neoteinic reproductive forms of Leucotermes 
flavipes were found 46 
XIII. Comparison of true and neoteinic or supplementary queens of Leuco- 
termes flavipes 58 
XIV. Neoteinic reproductive forms of Leucotermes virginicus 58 
XV. Dorsal, lateral, and ventral views of neoteinic nymphal or supple- 
mentary queens of Leucotermes flavipes 62 
XVI. Comparison of abdomens of young, fertilized, true queen and young 
and old mature kings of the same type of Leucotermes flavipes 62
