water. The corn suckers inhabited by the Diptera were also 

 very wet from the abundant juice of the wounded tissue. 



Chrysomyza demandata is a European species and there ap- 

 pears to be but a single reference to it in American literature. 

 This one item occurs in Entomological News, vol. xi, p. 609, 

 where a report of the entomological section of the Philadel- 

 phia Academy of Sciences contains the following paragraph: 



Mr. C. W. Johnson exhibited some flies he had found on the decay- 

 ed berries of a vine at the grounds of the Biological School of the 

 University of Pennsylvania. He also found one on decayed grapes at 

 Riverton, N. J. Mr. Coquillet determined it to be Chrysomyza de- 

 mandata, Fabr., a European species. Mr. Johnson did not know of 

 any previous record for American specimens. 



Mr. Ouaintance remarked on the large scope of the Bureau 

 of Entomology. Here was a paper based on an insect found in 

 a corn plot of an American Indian ! 



Mr. Webster said the Pima Indians are remarkable, having 

 raised corn and wheat from immemorial times, and that their 

 gardens show a peculiar insect fauna. The fly was described 

 from Sweden, but was here found in arid New Mexico. 



Mr. Walton told of collecting the fly rarely near Harris- 

 burg, Pennsylvania. 



Mr. Knab remarked that judging from the habits, the 

 species might enjoy a very extended range; it has been bred 

 in Europe from manure, and also from the contents of a silo. 

 -Under the heading Short Notes and Exhibition of Speci- 

 mens, Mr. Cushman described a peculiar spot of humid Texan 

 fauna in the midst of typical arid country. In June of 1908 

 he spent some time collecting insects along the Rio Grande 

 and in the Chisos Mountains in the extreme southern part of 

 Brevvster County, Texas. In a small area along the river, and 

 which was subirrigated from the river, the vegetation was of 

 much the same character as in the more humid portion of the 

 State along the Gulf coast and the insects collected were not 

 on the whole very different. But away from the river on the 

 high mesas and in the mountains the vegetation was almost 

 entirely xerophytic and the insect fauna, although abundant, 

 was entirely different from that of the subirrigated area. 



The Secretary read a letter from Mr. Schwarz describing 

 insect collecting in Panama.
