ence} 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 bromelicolous 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.

FELDMAN COLLECTING SOCIAL. 
Meeting of September 17th, 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, Culiseta inornatus 
Will., from Rockville, Pennsylvania, I1I-30-13. Also Brachyopa 
notata O. S. (Dip.), Harrisburg, Pa., [V-24-13, 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-20-13, and upon breaking it 
open found six specimens of this fly inside. The wasp had most

on the trees of the cerclos, or hedges, near Cartago, Costa Rica, we 
have seen them dry.
