 TOMOLOGICAL CLUB. AMERICAN ASSOCIATION FOR THE 

 ADVANCEMENT OF SCIENCE. 



AUGUST 17-19. IS'92. 



Seven sessions of tlie Club were liekl in tlit^ Eocliester Cniversity, 

 Eocliester. X. Y,. ^vitli an attendance of 25 members and an average 

 attendance at each meeting of 15. Tlie follomng brief abstract of tlie 

 pa]3ers read at tlie different sessions lias been prepared for Ijs'SECT Life 

 "by tlie Secretary upon tlie resolution of the Chib. 



Tlie first meeting. Angiist 17. was opened by tlie President. Xr. E. 

 A. Schwarz. of WasMngton. with his annual address. ]\lr. Schwarz 

 took 11X3 Prof. Osborn's suggestion proposed at the Washington meeting 

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

 American insects. He reviewed the work hitherto done on Xortli 

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

 is concerned, a manual of Coleoptera giving synopses of genera and 

 species can now be prepared which, in usefulness and scientific value, 

 would comi>are favorably with Eedtenbacher's well known work on 

 European Coleoptera. Proceeding to the biologic branches of Coleop- 

 terology he showed that, mainly owing to the many difiiculties wliicli 

 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 Coleoptera. 



Mr. D. S. Kellico'n: presented a paper on the preparatory stages of 

 CaJotJn/sanis amo.turaria, showing that the larviiE' of this species are very 

 abundant during July and August at Columbus. Ohio, upon Fojy- 

 gonum dirmetorum. 



Air. F. 31. AVebster gave some notes on the insects reared n^im a gaU 

 on ^luhlenhergia mexicana, showing that six species have been reared, 

 as follows: An Oscinid. aPteromalid. a Eiuwtomid. great numbers of 

 Lasiopteia. seveial Polygnotus. and several Eupelmus. 



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

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

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



Prof. C. V. Eiley read a i^aiier showing that GaJervea xontlwmel^en 

 is polygoneutic at Washington, normally two and sometimes thre^ 

 broods occurring there. The greater pait of the second brood hiber- 

 nates, though a few lay eggs for a third generati- m. 



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

 neutic at 2s ew Brunswick. X. J. This one brood goes into winter quar- 

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