A large majority of these moths and butterflies 

 had two or three pairs of poUinia attached to them, 

 and invariably to the proboscis. The Acontia had 

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



Caradrina no less than eleven 

 pair ! The proboscis of this 

 latter moth presented an ex- 

 traordinary arborescent ap- 

 pearance. The saddle-formed 

 discs, each bearing a pair of 

 poUinia, adhered to the pro- 

 boscis, one before the other, 



witn perfect symmetry ; and Head and proboscis of Acmtia luc-

 proboscis into the nectary in exactly the same manner, 

 owing to the presence of the guiding plates on the 

 labellum. The unfortunate Caradrina, with its pro- 

 boscis thus encumbered, could hardly have reached 

 the extremity of the nectary, and would soon have 



* I am indebted to Mr. Parfitt 

 for an examination of this moth, 

 which is mentioned in the ' En- 

 tomologist's "Weekly Intelligencer,' 

 vol. ii. p. 182, and vol. iii. p. 3, 

 Oct. 3, 1857. The poUinia were 



erroneously thought to belong to 

 Ophrys api/era. The pollen had 

 changed from its natural green 

 colour to yellow ; on washing it, 

 however, and drying it, the green 

 tint returned.
