Doings of Societies. 
At the meeting of the Feldman Collecting Social held Sep- 
tember 17, 1908, at the residence of Mr. H. W. Wenzel, 1523 
South 13th Street, Philadelphia, seventeen members were pres- 
ent, also Mr. O. T. Elleder of Russia, Mr. W. S. Fisher of 
Highspire, Pa., and Mr. R. Pearce of Philadelphia, visitors. 
Prof. Smith spoke of the spread of Daremma catalpae Bois. 
throughout the State of New Jersey and its great abundance 
during several years. In 1906 it began to lessen in numbers in 
the regions that were first invaded, and parasitism became 
more obvious. In 1907 this tendency became even more mark- 
ed, and during the season of 1908, the larvae were really rare 
in most parts of the State, parasites seeming to have caught 
up with the species, and brought it under control. He also 
spoke of other natural controls of injurious species and ex- 
pressed his opinion that no one kind of check was controlling 
for all species, that diseases in one case did what parasites did 
in another, and that weather conditions were often as impor- 
tant as either, acting independently or with one or both the 
other factors. Some cases of hyper-parasitism were also re- 
ferred to as influencing the effect of the primary forms. Dis- 
cussed by Mr. Viereck, Prof. Calvert and Dr. Skinner. 
A letter from Mr. Roswell H. Johnson to Mr. H. W. Wenzel 
was read and specimens illustrating the color variation of Hip- 
podamia convergens-quinquisignata group were shown. 
Mr. H. W. Wenzel exhibited pieces of floor boards of second 
story of a club-house at Anglesea, N. J., which were infested 
with Hylotrupes bajalus. The work of the insect is invisible 
until the destruction is complete. Dr. Skinner spoke of a case 
of the same insect, where the damage done was not noticed 
until the piano had fallen into the cellar. 
Mr. Elleder spoke about his collecting of Coleoptera in this 
country. He has been collecting in and near Philadelphia for 
about one year, and finds that many of the families are com- 
paratively rare here. The Cicindela on the other hand are re- 
presented in all of Russia by only four species, while here they 
are very numerous, and he suggested that a Cicindela should 
be incorporated in the coat of arms of New Jersey. The gen-.
