organs; the former being a single sense cell whose peripheral end pierces 

 the integument, and the latter being a group of sense cells whose 

 peripheral ends pierce a common plate; the compound organs are 

 found only on the antennae of a certain coleopterous larva. (3) The 

 antennal organs discussed are the pore plates, pegs, pit pegs, and end 

 pegs; each of these organs is innervated, but the nerve does not come 

 in direct contact with the external air as it does in the lyriform organs 

 and olfactorj^ pores. 



Bees recognize one another chiefly by the odors they emit; in a colony 

 there are a queen odor, drone odor, family odor, individual odor, and a 

 hive odor. The hive odor is the most miportant one, because without 

 it a colony of bees could not exist. These odors are produced by a 

 special scent-producing organ. 



The tactile sense of bees is very acute, and these insects can dis- 

 criminate between certain foods better than people, although they have 

 no sense of taste; this is accomphshed by means of the highly devel- 

 oped olfactory sense after the bees have eaten a little of the foods. 



The paper was discussed by Dr. L. 0. Howard and Alex. Wetmore. 



Eleanor C. Allex: Wax models of fleshy fungi, with an exhibit of 

 several models. ]Miss Allen said she had been engaged for the past 

 four years in making models of this sort for the Milwaukee Public 

 Museum. She illustrated her talk bj' models of four species of mush- 

 rooms, each being represented bj- a group of several individuals ar- 

 ranged as in their living condition. She described the processes inci- 

 dent to the making of the finished groups. Living specimens growing 

 in woods or fields are found and before picking sketches of the group 

 and complete notes in regard to color and habitat are made. Then 

 plaster models of the various individuals are made. In the laboratory, 

 using these models, wax mushrooms are cast and the details of these 

 are worked out by careful modeling, coloring, and the addition of 

 various materials to give a natural appearance of texture. Habitat 

 material such as grass, moss, stumps, etc., are gathered and chemically 

 treated. Backgrounds, natural to individual species, are prepared from 

 these materials and upon these the wax facsimiles are arranged. 

 Miss Allen showed photographs of the numerous groups which she 

 has made and which are now installed in the Milwaukee Public Museum. 



Miss Allen not being a member of the Society was introduced by 

 President Rose. Her communication was discussed by the chair, and 

 by Alessrs. F. V. Colville and A. S. Hitchcock. 



C. B. Doyle: Some agricultural and botanical features of Haiti, illus- 

 trated b}^ lantern slides. In Haiti there is very little left to repre- 

 sent the original forest covering. The primitive milpa system of 

 agriculture is used and the natives live in scattered families or small 

 groups. ^lost of the food plants are of American origin, butit is the 

 introduced species that have become of the greatest importance to the 

 natives. There are only a few large plantations on the island, the bulk 

 of the crops of the three principal exports (coffee, cacao, and cotton) 

 being produced on the small native farms. Many different kinds of
