Adult: Fig. 31,Plate XX XIII. 
Head black, yellowish red between the eyes; pronotum black with 
lateral thirds yellowish red; elytra black; legs brownish red; entire 
beetle covered with hairs; length 2.5 mm.; width 1.7 mm. 
Egg: 
Same color and shape as foregoing species but much smaller. 
Larva: Fig. 32, Plate XX XIII. 
Pale brownish throughout, but covered with six large tufts of waxy 
secretion on each segment so as to render the larva quite conspicuous. 
In the pupa the larval skin is not pushed down as tightly as in the 
other Coccinellids studied, so that it gives the pupa a white cottony 
appearance and doubtless affords it considerable protection. 
This species has often been found doing valuable service in 
keeping <A. setariae in check on the plum. Professor Gillette 
has often found it abundant with Schiz. lanigera on the apple. 
GENERAL SUMMARY. 
In general appearance and color pattern these species of 
ladybeetles resembled each other most in the larval and pupal 
stages. Coccinella 5-notata, 9-notata, and monticola resemble’ 
each other so much as to form one group. They of course had 
some characteristic differences but they often intergraded and 
merged together so as to be indistinguishable until they matured. 
H. convergens, together with H. parenthesis and H. sinuata 
seemed pretty distinct in these stages but an occasional indi- 
vidual was found which seemed to show no distinguishing 
character. The Adalia beetles, O. abdominalis, and C. sanguinea 
seemed to form another group in color pattern of the larva and 
pupa. The forms of the Adalia seemed to be exactly identical 
in these early stages. Scymnus, of course, with its covering 
of waxy secretion, was entirely different. 
In life cycle periods from egg to adult, all the species thus 
studied, H. convergens, C. 5-notata, 9-notata, monticola and the 
genus Adalia seemed practically alike. From egg to adult 
in H. convergens took, as a rule, 21 days; in C. 5-notata, 20 
days; in C. monticola, 23 days; in 9-notata, 20-23 days; 
Adalia, 21-23 days. The age to which the adults lived seemed 
practically the same, two to three and perhaps four months for 
the summer generations. In C. monticola, however, it seemed 
that the first generation commonly hibernate so that these 
beetles would live to a greater age than even the hibernating.
