PLATE 6 
Larva of the honeybee 
A. —Longitudinal section through the junction of mid-intestine and hind 
intestine of mature larva just prior to capping of the cell. The section passes 
through the central blind ends of two Malpighian tubules ( Mal) } one on each 
side. X 92. 
B. —Longitudinal section through the junction of mid-intestine and hind 
intestine of a larva 12 hours after capping, showing the establishment of commu¬ 
nication between the mid-intestine, hind intestine, and Malpighian tubules. 
The opening of one of the latter into the hind intestine is to be seen on the left 
side. X 92. 
C. —Head of larva, left side, showing musculature. From a stained and 
cleared preparation. X 26. 
D. —Coronal section of head of mature larva, intersecting the posterior arms 
of tentorium (2 Ten). X 60. 
E. —Tangential section of wall of heart, showing cells of wall ( HtCls ) and 
connective tissue ( ConCls ). From the region of the fourth abdominal segment.
