encef of water in the aquarium, its darkness, etc., lead to a number of 

 highly interesting differences in the animals which inhabit even the same 

 plant. The origin and dissemination of the brorhelicolous fauna is dis- 

 cussed and comparisons made with the biology and fauna of other 

 "Reservoir Plants." Chapter IV is more technical and is composed of 

 descriptions of larval and adult stages of a few Diptera, Hemiptera, 

 Coleoptera and an earth worm from Costa Rican Bromeliaceae. The 

 brief chapter V is a summary of twenty "Conclusions." There is a bibli- 

 ography of three pages, while an Appendix (pp. 333-360) lists all the 

 bromelicolous animals from Rotifers to Batrachians known to the au- 

 thor. Previous to his own researches about one hundred such species 

 were known; he has brought the total up to about 250, of which forty- 

 nine were new. The work is highly valuable and well worth reading, 

 even by those who have not the opportunity to work with these plants, 

 on account of its suggestiveness.

Doings of Societies. 



FELDMAN COLLECTING SOCIAL. 



Meeting of September i7th, 1913, at 1523 South Thirteenth 

 Street, Philadelphia. Ten members were present. J. C. Brad- 

 ley, of Ithaca, N. Y., visitor. President Haimbach in the chair. 



Dr. Castle said he had gotten a few good things in Maryland 

 and near Harrisburg, Pa., but on the whole collecting was very 

 poor. 



Mr. Daecke exhibited a rare mosquito, Cnliseta inornatus 

 Will., from Rockville, Pennsylvania, 111-30-13. Also Brachyopa 

 notata O. S. (Dip.), Harrisburg, Pa., IV-24-I3, which had been 

 recorded from Washington, Oregon, Quebec, Alaska and moun- 

 tains of New Hampshire, the latter being the most southern 

 locality. He said that Oncodes dispar Macq., a little yellow 

 fly, breeds on spiders ; Champlin had found a mud wasp nest 

 in a stump at Harrisburg, VIII-2O-I3, and upon breaking it 

 open found six specimens of this fly inside. The wasp had most 



fSenor Picado speaks (pp. 236, 255) of the epiphytic bromeliads con- 

 stantly retaining water, but in some situations, as on isolated trees or 

 on the trees of the cerclos, or hedges, near Cartago, Costa Rica, we 

 have seen them dry.
