instar: Same as third except for the addition of pale orange spots on 
the 6th and 7th segments on dorso-lateral portion, not extending later- 
ally. Some larve show quite a bluish frosted appearance over the black, 
more especially toward the later stages. Length about 9.5 mm. for a 
full grown larva. 
Pupa: Fig. 4, Plate XXXII. 
Ground color brownish yellow throughout; pronotum with black 
lateral margin and an anterior and a posterior pair of black spots; 
wing pads black along posterior margin and over apical half; each 
segment with sublateral and medio-lateral spots. Spiracles black. 
Sometimes much lighter in general color and only a dot found on wing 
pad at basal third. Legs black. Length 5 mm. 
Life cycle records* were made as follows: 
Egg stage (22 records*) 3-7 days, mostly 3 days; 
Larva stage (22 records) 10-28 days, mostly 14 days; 
Pupa stage (22 records) 4-9 days, mostly 4-5 days; 
Egg to adult, mostly 21 days. 
Adult stage (13 records) 3-4 months for the summer generations. 
A hibernating female lived 8 months and 12 days, dying May 
25th, having laid eggs from April 27th to May 19th. This female 
would doubtless have lived longer under natural conditions. 
The weather was wet and unfavorable and the female was evi- 
dently in a weak or unhealthy condition as evidenced by the 
poor hatching of all the eggs. Another hibernating female 
lived until July 6th. All the females which had laid eggs before 
going into hibernation died either during the winter or in the 
spring before laying any eggs. A male which had hibernated 
lived 9 months and 8 days, dying June 13th. 
The earliest egg record obtained was April 27th, the latest 
record in 1908 was September 3rd, and in 1907, was October 
30th. The earliest beetles reared emerged June 22nd and the 
last one lived until September 22nd. Under natural conditions 
and in early spring, doubtless the first generation emerges as 
soon as the latter part of May or even earlier, according to the 
season. There were at least three generations obtained in a 
season. 
The females would usually begin to lay within five days 
after emerging and the longest egg-laying record obtained was 
1 month and 18 days. Several egg counts were made. They 
are as follows: 130 eggs (in 20 days), 199 eggs, 296 eggs, 312 
eggs (in 1 month and 15 days), and 399 eggs, by different 
*The term, record, in this sense shall be understood to mean, not notes made 
on a single individual, but on an egg patch and the beetles resulting therefrom.
