A large majority of these moths and butterflies 

 had two or three pairs of pollinia attached to them, 

 and invariably to the proboscis. The Acontia had 

 seven pair (fig. 4), and the Fig. 4.

 latter moth presented an ex- 

 traordinary arborescent ap- 

 pearance. The saddle-formed 

 discs, each bearing a pair of 

 pollinia, adhered to the pro-

 owing to the presence of the guiding plates on the

erroneously thought to belong to 

 Ophrys apifera. The pollen had 

 changed from its natural green 

 colour to yellow : on wasliing it, 

 however, and drying it, the green 

 tint returned.
