Beetles that had hibernated, died in the insectary July 5, 9, and 
26, after having been kept there with proper food, etc., since winter. 
By July 5 most of the beetles are gone from the fields ; only a few 
stragglers continue to live, there being a conspicuous break between 
the last of the wintered beetles and the first beetles of the new gen- 
eration. Larvae, nearly or quite grown, and pupse are common in 
old clover stems July 28 to August 7. About July 30 the larvae are 
three times as numerous as the pupae ; but after the first week in Au- 
gust the latter exceed the former in number. The new beetles emerge 
mostly thruout August and during the first half of September. In 
the insectary they issued almost every day from August 3 to Sep- 
tember 14, and one emerged September 20. Most of them have is- 
sued by August 26, however. At that date the burrows are almost all 
vacant, and the beetles are abroad in the field, feeding a little, seeking 
shelter at every cold spell, becoming more and more sluggish, and 
finally dormant. Not until spring does the reproductive instinct 
awaken. 
Habits. — Oviposition occurs to some extent late in May and early 
in July, but for the most part in June, and has been witnessed in the 
daytime. The female gnaws a small pit on the stem of a plant, as 
Chittenden and others have observed. On clover stems these pits can 
be found easily. Unless freshly made, the pit is brown, in contrast to 
the green of the stem ; a pit that is green is less than twenty-four hours 
old, and indicates, as a rule, the presence of an egg. The egg-pit is 
shallow, oval or round in outline, and not more than one sixteenth of 
an inch in length. In the center of the pit a minute linear or elliptic- 
al slit opens into the pith. Upon cutting open the stem, the egg is 
seen on the inner wall of the stem, often opposite the pit, but sometimes 
as far from it as four to six millimeters. The female makes the pit 
with her mandibles, then pushes the end of the abdomen thru the bot- 
tom of the pit and into the pith, these operations taking eight minutes 
in one instance axid sixteen in another, as observed by E. O. G. Kelly. 
.Sometimes a female gnaws out a pit without laying the egg. In red 
clover the eggs are laid singly, almost invariably, in my experience, 
rarely two being found together. In another plant {Lencanthenutui) . 
however, Mr. Girault saw at least fifteen eggs deposited in the same 
nidus (Ent. News, Vol. XVIII., pp. 366, 367). 
The egg-pits occur on the main stem of a red clover plant any- 
where from three to twenty inches from the ground, averaging ten 
inches, the old pits having been carried up more or less by the growth 
of the stem. Fresh pits, especially those on small stems, are usually 
not far from the ground. 
The larva, feeding on the pith (Fig. 27), tunnels out the main stem 
for sometimes two feet. If two larvae occupy the same stem their 
combined efforts may produce a burrow as long as thirty-two inches, 
extending from the main stem out into one of the larger branches. 
The largest larvae and the pupae (Fig. 28) are found usually at the 
lower end of the burrow, an inch or two from the ground, the pupa
