Pupa. The pupa, when freshly transformed, is creamy white in 
color. As development proceeds, the darker colors of the adult insect 
are assumed. Pupation occurs during late May, June and early July, 
having been noted as early as May 30, and as late as July 11. The 
length of the pupal stage varies from eight to 20 days. In all, 212 
pupas were observed for the length of this stage. Among grubs reared 
from eggs, the pupal stage averaged 10 days for 16 pupae. Grubs 
collected in the field averaged 12.5 days in 1922 for 153 instances, and in 
1923, 43 pupae had an average period of 9.9 days. These data are 
summarized in Table IV.

Summary 
This new species of the genus Anomala , because of its widely varying 
feeding habits and rather general occurrence in the region in which it is 
found, bids fair to become of considerable economic importance. The 
beetles feed at dusk and fly to lights. Eggs are laid in the soil in June 
and July and require an average of 12.2 days for hatching. The larvae 
live in the soil over winter. Molting occurs twice. The first molt occurs 
on the average 20.5 days after hatching and the second molt, an average 
of 16.8 days after the first molt. The total larval stage varied from 322 to 
345 days, with an average of 336.3 days. From this should be sub¬ 
tracted an average of 4.06 days for the prepupal stage. The pupal con¬ 
dition lasts from 8 to 20 days. Pupation occurs in late May, June and 
early July. After transforming to the adult stage, the beetles soon 
appear above soil to feed and reproduce. 
THE CORRECT NAMES OF THE LEAFHOPPERS INFESTING 
THE APPLE AND POTATO 
By E. D. Ball 
Abstract 
There has been much confusion and misunderstanding with respect to the scientific 
and common names to be applied to the three species of leafhopper infesting the apple,
