Larva: Fig. 14, Plate XXXII. 
Indistinguishable from that of H. convergens until it reaches the third 
or fourth instar when the head becomes pale, except on the posterior 
and lateral margins, which remain black. Also, the yellow spots on the 
abdomen are usually a stronger orange color and the dorso-lateral spots 
on the 6th and 7th segments are lacking. The light blue frosted appear- 
ance is sometimes more pronounced than in H. convergens. Length 
about 12 mm., for a full grown larva. 
Pupa: Fig. 15, Plate XXXII. 
Ground color pale brownish yellow, tinged in places with pinkish, 
paler, as a rule, than in the case of H. convergens. Pronotum with nar- 
row black margin all around, except on median posterior portion; wing 
pads black on posterior and apical two-thirds of anterior margin, also 
two spots, one at basal third, and the other at apical third. These 
spots often coalesce, darkening the whole apical two-thirds of the wing 
pad. On the metathorax is a pair of black spots on the posterior 
margin, medio-laterally placed; spots similarly placed on 2nd to 7th 
segments inclusive, which segments also show another spot just within 
the spiracles which often runs into the first mentioned spots along the 
posterior margin. On the 3rd segment, the black often covers the entire 
surface clear to the lateral edge, leaving only a pale line on the median. 
Seventh segment often pale or nearly so. The amount of black varies 
somewhat and is often less extensive, but the pupa can usually be dis- 
tinguished from that of H. convergens by the more extensive black 
markings, and by the paler ground color, but this does not always hold. 
Legs black. Length, 6 mm. 
Life cycle records were made as follows: 
Egg stage (15 records) 3-5 days, mostly 3 days; 
Larva stage (13 records) 11-19 days, mostly 13 days; 
Pupa stage (12 records) 3-8 days, mostly 4 days; 
Egg to adult, mostly 20 days. 
Adult stage (4 records) 2-3 months for the summer generations. 
The efforts to carry this species through hibernation all 
resulted in failure, but seven beetles were captured before May, 
19, 1908, which, in all probability, had hibernated, as no 
larvae had been observed before that time or for some time 
afterwards. The last of these beetles lived until August 14th, 
and must have lived for nearly a year, as the beetles in the 
cages which went into hibernation began to emerge August 
6th. In the cage of these seven captured beetles, eggs were 
found from May 19th to August 7th, a period of two months 
and eighteen days. 
Egg records were made as follows: 368 eggs (in 2 months 
and 9 days); 469 eggs (in 1 month and 11 days), 532 eggs (in 1 
month and 8 days), 539 eggs (in 1 month and 2 days) respective- 
ly. Single egg batches often contain as many as 60 eggs; the
