. British bee journal & bee-keepers adviser. Bees. Feb. 4, 1915.] THE 13IIITISH BEE JOURNAL. 33. REVIEWS. The Olfactory Sense of Insects, by N. E. Mclndoo, , published by the Smithsonian Institution, Washington, —Although a great many investigators have mentioned different parts of insects in this connection, no one has hitherto collected the views of the varioiTS writers on the sense of smell in insects. The author, therefore, in this work discusses briefly for the use of students the litera- ture that bears directly on the subject. After alluding to the sense of smell in general, he gives the opinions of a large number of writers who locate the olfactory organs in different parts of the body, such as the spiracles, glands of the head and thorax, oesophagus, folded skin beneath the antennte, rhinarium, month cavity, palpi, antennae, etc. Dr. Mclndoo carried out a number of experiments on different insects, but those relating to bees will interest bee-keepers most. After experi- menting on the antennse, which have been pretty generally considered to carry the organs of smell, he conchides that this is not correct. He agrees with Hicks, who first drew attention to them, that groups of what the author designates as olfactory pores are situated at the bases of the wings, and on the legs, while some lie on the sting of the worker and queen bee. The same organs are found on the mouth parts of all hymenopterous insects. In the discussion at the end of the work the author points out why the different structures, such as the pore plates, pegs or cones, and Forel's flasks, can be eliminated as olfactory organs, and gives several examples in connection with the honey bee of the manner in which the different bees respond to odours presented to them. Pore plates are entirely absent in the Lepidoptera. After giving reasons for eliminating the other structiires, be concludes that the organs which he calls the olfactory pores are the true olfactory apparatus in Hyme
