the reservoir is smaller, the homologous 
tube is short, and ends in a knob-like ex- 
pansion in the interior of the reservoir.

Moreover, the tube does not simply pierce 
the wall of the reservoir, but pushes it in- 
wards, as it were, thus making for itself 
another envelope. The histology of the 
different parts is fully discussed, and many 
important general deductions are made. 
Besides the poison apparatus, Forel has 
discovered that the Dolichoderidae also 
possess anal glands and sacs, similar to 
those found in many insects, especially 
beetles. This anal sac lies above the di- 
gestive tract, and opens above the anus. Its 
secretion is probably mephitic, and recalls 
the secretion of Wolff’s mandibular glands 
in the bees. The author believes that 
Wolff is greatly in error in regard to his 
supposed organ of smell in the bees, which 
have indeed little development of this sense. 
From simple experiments on Polistes the 
antennae certainly seem the seat of the or- 
gan in question.
