10 THE FLORIDA ENTOMOLOGIST 
A LADY-BEETLE NEW TO FLORIDA 
Mr. Geo. F. Merrill adds to the list of Florida Coleoptera the 
white lady-beetle Olla abdominalis Say. It was sent in from 
Tampa. Its range has hitherto been given as Indiana to Texas 
and west.

-star, they do not overlap. In the first two instars the head is 
black, in the last two it is strikingly banded with white in the 
form of a narrow white band completely encircling the face on 
the margin and an inverted white V on each side of the face. 
In the last instar the vertex becomes reddish-brown. The third 
instar, however, presents both black heads and those striped 
with white as described for the fourth and fifth. This variation 
may be due to sex though this was not proven. Two larvae 
taken near together and having exactly the same head widths 
showed this difference. 
As the larva prepares to molt the new head is formed within 
the body just caudad of the old one and shortly before the skin 
breaks there appear to be two distinct heads, even the mark- 
ings of the new one showing through the epidermis. All the 
head casts are discarded unbroken except the last one which 
ruptures along the frontal suture. The pellicles of all except 
the last molt are very delicate and difficult to find. The larva 
is pale gray when freshly molted. 
A day or two before pupation the larva becomes covered with 
a distinct while pulverulence. We have observed its first ap- 
pearance as much as four days before pupation as two powdery 
white areas on the ventro-lateral margin of the body just caudad 
of the caudal pair of legs. From this point it spreads until the 
whole body is covered. It is all carried away with the last 
exuvium which remains attached to the head cast and is much 
more bulky than any of the preceding. 
Twenty larvae were reared, nine of them completely through 
from egg to adult. The following table shows in days the length 
of the different instars and the total larval life.
