ABSTRACT OF PROCEEDINGS, ROCHESTER MEETING OF THE EN- 

 TOMOLOGICAL CLUB, AMERICAN ASSOCIATION FOR THE 

 ADVANCEMENT OF SCIENCE. 



AUGUST 17-19, 1892. 



Seveu sessious of the Club were held in the Eochester University, 

 Eochester. IsT. Y,, with an attendance of 25 members and an average 

 attendance at each meeting of 15. The following brief abstract of the 

 papers read at the different sessions has been prepared for Insect Life 

 by the Secretary upon the resolution of the Club, 



The first meeting, August 17, was opened by the President, Mr. E. 

 A. Schwarz, of Washington, with his annual address. Mr. Schwarz 

 took up Prof. Osborn's suggestion proposed at the Washington meeting 

 of the club, to prepare, by cooperation, a scientific manual on North 

 American insects. He reviewed the work hitherto done on North 

 American Coleopterology, and pointed out that, so far as classification 

 is concerned, a manual of Coleoi)tera giving synopses of genera and 

 species can now be i)rei)ared which, in usefulness and scientific value, 

 would compare favorably with Eedtenbachcr's well known work on 

 European Colcoptera. Proceeding to the biologic branches of Coleop- 

 terology he showed that, mainly owing to the many difficulties which 

 surround the subject, the work hitherto done is very fragmentary and 

 in part also unsatisfactory. He concluded his address with an appeal 

 for more work and more workers in the biology of the Colcoptera. 



Mr. D. S. Kellicott presented a pai)er on the preparatory stages of 

 Galothysams amaturaria., showing that the larvae of this species are very 

 abundant during July and August at Columbus, Ohio, upon Poly- 

 gonum dumetorum. 



Mr. F. M. Webster gave some notes on the insects reared from a gall 

 on Muhlenber</ia me.ricana, showing that six species have been reared, 

 as follows: An Oscinid, a Pteromalid, a Eiirytomid, great numbers of 

 Lasioptera, several Polygnotus, and several Eupelmus. 



Dr. C. W. Stiles discussed a cutaneous disease of cattle, in which 

 slight lumps are to be seen along the back and fianks. Upon examina- 

 tion these were found to be caused by an Arachnoid, Demodex sp. 



Prof. C. Y. Eiley read a paper showing that Galeruca xanthomela'na 

 is polygoneutic at Washington, normally two and sometimes three 

 broods occurring there. The greater ])art of the second brood hiber- 

 nates, though a few lay eggs for a tliird generation. 



The same insect was shown by Prof. John B. Smith to be monogo- 

 neutic at New Brunswick, N. J. This one brood goes into winter quar- 

 ters at about the same time as the second brood at Washington.
