542 INJURIOUS AND BENEFICIAL INSECTS. 
the preceding. We know but little of its habits. Harris says 
that it invariably appears with the beginning of the dog-days, and 
in the vicinity of Boston he has heard it for many years in suc- 
cession, with only one or two exceptions, on the 25th of July, for 
the first time in the season. According to Prof. A. E. Verrill, in 
our “Guide to the Study of Insects,” it lays its eggs in the stems 
of the solidago or golden rod. ‘It made a longitudinal incision 
with ragged edges into the pith of the plant, then with its ovi- 
positor forced its eggs a little distance down into the pith below 
the external opening: there were two rows of eggs succeeding 
Fig. 144, the first single one, each pair diverging out- 
wards, the lower ends of each pair nearly 
touching each other, and all placed very near 
together.” 
The pupa (fig. 144) is much the largest a en of the 
Pupa = — pru- three species, being nearly twice as bulky hat of the two 
thers. The head is very broad, short, pren: much 
shorter than in ae seventeen-year locust. There are no dark bands crossing the 
dy. Itis an inch in length and nearly one-half (45) an inch wide. 
smaller species, the least cicada (C. rimosa), expands & 
little less than two and a half inches, and has a narrow head, with 
bright red markings on the head and thorax. For several years 
in Brunswick, Maine, I have noticed that it began its song on the 
10th of June, and in this state it probably sings by the Ist of 
that month.
