12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 63 



Sulzer (1776) contends that insects have an acute sense of smell 

 and spoke of bees coming for honey when it is placed in a spoon 

 under a window. He believes that the olfactory apparatus is located 

 in the antennas. 



Fabricius (1778) infers that the seat of smell belongs to the 

 antenna?. 



Bonnet ( 1781) asserts that diverse insects have the sense of smell 

 exquisitely developed, but that we do not know where the seat of 

 this sense lies. He suggests the antenna; as a possible location. 



In discussing the probable uses of the antennae, Olivier (1789) re- 

 garded them as olfactory in function. 



Latreille ( 1804) regards the fact that many male insects have the 

 antennae better developed than the females of the same species as 

 evidence that these appendages are the seat of olfaction. The greater 

 number of insects that live in animal matter, in decayed vegetables, 

 or in stagnant water generally have the antennae better developed than 

 those that live elsewhere. A more perfect olfaction would be neces- 

 sary to these insects, and the organization of the antennae seems to 

 be adapted for this purpose. 



After discussing Marsham's account of ichneumon flies, Samouelle 

 (1819) states, "From these remarks may we not infer that the 

 antennae may be the organ of smelling? " . 



De Blainville (1822) and Robineau-Desvoidy (1828), cited from 

 Perris (1850), state that the antennae are olfactory organs. 



After briefly discussing the various views concerning the seat of 

 olfaction, Carus (1838) confesses that the opinion of Rosenthal, 

 combined with that of Reaumur, appears to him to be the best. 

 Hence he believes that the seat of olfaction lies in the folded skin 

 beneath the antennae as well as on the surface of the antennae. 



Since the antennae of the male are often better developed than 

 those of the female, Percheron (1841) states that the antennae of 

 the male aid the eyes in searching for the female. He infers that 

 the antennae are used for smelling. 



Goureau (1841) thinks that the antennae may be organs of olfac- 

 tion besides being organs of touch and hearing. 



Pierret (1841) also favors the view that the seat of olfaction lies 

 ill the antennae. 



Robineau-Desvoidy (1842) speaks of an olfactory apparatus as 

 nothing less than an ordinary organ of touch which is capable of 

 receiving invisible stimuli. By analogy he thinks that the antennae 

 must be the organs of smell.
