(Fraxinus orcgona and dipetala) in Washington, according 

 to Prof. O. B. Johnson, while it breeds in California Laurel in 

 this State. Mr. J. F. Killeen said that it also breeds in maple 

 (Acer macrophylliim). Mr. Nunenmacher stated that the spe- 

 cies is very abundant at Irvington, Alameda Co., California, 

 and that it comes to the light. 



Dr. Creighton Wellman stated that he had been working 

 regularly, since the last meeting of the Society, on the Meloidae 

 of East India, and that he had received the material from 

 museums and private collections. Mention was also made of 

 the faunal regions covered by his studies. 



Dr. Van Dyke stated apropos of Dr. Wellman's remarks, 

 that from some observations which he had made upon various 

 species from the Sonoran, the Mediterranean and Aral-Caspian 

 basin, and the Australian regions, he had come to the con- 

 clusion that the more typical part of the fauna of these three 

 dry regions had a common origin, and the faunae therefore 

 were not secondary to their adjacent tropical regions, but 

 were of equal standing with them, and to a very great extent 

 independent. 



Dr. Wellman then stated that Zonitis and Lytta are the 

 most primitive genera of the Meloidae. 



Mr. J. F. Killeen made remarks on Coccinella trifasciata 

 and Adalia bipuiictata. He further stated that he had been 

 experimenting on ants. These pests were trapped with bouillon 

 poisoned with arsenic or strychnine. 



Prof. W. B. Herms, of the Entomological Department of 

 the University of California, being called upon, stated that he 

 was interested in the sensory reactions of organisms to stim- 

 uli ; and that he was working in Medical Entomology, study- 

 ing the distribution of Anopheles, and their reactions. 



Mr. J. C. Bridwell, recently from Oregon, and a Hymenop- 

 terist, being called upon, said that what little collecting 

 lie had done in California showed that there was a great var- 

 iation in the species, and he considered that there was great 

 need of rearing insects, in order to study variations, as we 

 have too many species listed. He believed that we should rear
