I have of actually finding the beetle is June 19. This may have been — 
and probably was — one of the new brood, the adults of which are not 
uncommon in the last week of June and become common by the middle 
of July. They emerge over a considerable period, as our records 
show, our dates of emergence being July 10 and 16, and August 20 and 
25. The pupal period is two to three weeks. Thru July, Au- 
gust, and September the beetles are common in the field, where we 
have found them as late as October 8, 14, and 31, and November 25; 
and indoors, they may be kept alive far into the winter and doubtless 
until spring. Like the clover leaf-weevil, these other curculios feed 
for a long time before mating and laying eggs. Dates of coition are 
July 1 (exceptionally early) ; August 26, 30, and 31 ; September 1, 8, 
10, 15, and 27; October 10, 18, and 25; and November 14. All these 
records except those of September 8 and 10 were made in the insec- 
tary (unheated but yet aflrording some protection from frost), and out- 
of-doors mating and oviposition would not occur for quite so long a 
time. Two to ten days elapse between coition and egg-laying. In 
the field most of the eggs are laid in September. Indoors we have 
found them to have been laid September 12, 14, 15, 19, 20, 22, 25, 26, 
27, and 29; October 23 and 27; and November 1, 2, 3, 4, 5, 10, 14, 16, 
17, and 23. For several years we have kept the beetles in abundance 
under daily observation thruout their long lifetime, without getting 
other dates of oviposition than these. A single female lays her eggs 
at irregular intervals ejitending over several weeks. Thus a female 
which copulated October 25 laid eggs October 27, November 2, 10, 17, 
and 24. The egg period varies, even under conditions apparently the 
same, and ranges from 13 to 32 days. Hatching occurred in the in- 
sectary from October 17 to November 29, mostly in November, and 
most of it before winter. Not a few eggs, however, failed to hatch in 
autumn, and did not hatch the following spring, when they were 
evidently dead. There remains, nevertheless, the possibility that some 
eggs survive the winter. 
The species winters chiefly as a young larva, but occasionally sur- 
vives as a beetle in this region. 
Webster dug up frozen clover sod on December 9, at Lafayette, 
Ind., and found therein, after thawing it out, Sitones larv?e, some of 
them 1 mm. long, most of them under 2.5 mm. in length, and two 
full grown and in earthen cells. He found also two beetles, but no 
pupae. One of the adults was still alive February IS. April 13 he 
found in the field, larvae (less numerous than in December, and in 
about the same stage of growth), no pupse, and two beetles, which died 
soon afterward. May 25 he obtained larvae (less numerous than in 
April, but now nearly or quite full-grown) and pup?e, and a single 
adult, which died May 30. These beetles laid no eggs. June 14 he 
found several adults. I 'regard these as belonging to the new brood. 
Webster's account serves almost exactly for the species as it oc- 
curs here in Urbana. He found, however, that eggs laid October 17 
and 25 hatched in about 48 hours at a temperature of 65° F. — a much
