 In addition to the insects feeding upon cacti, their 

 enemies or parasites are listed and also the scaven- 

 gers, flower visitors, and incidentally associated 

 species. This is a social community composed of 

 324 species of insects, and it forms an excellent 

 foundation for a study of their interrelations. This 

 is more ecological than is usually the case in eco- 

 nomic reports. 



MOLLER, L. 



1867. Die Abhangigkeit der Insecten von ihrer Umgebung. 



pp. 107. Leipzig. W. Englemann. 

 A very interesting and suggestive work. An excellent 

 local habitat study from the standpoint of insects. 

 Apparently not known to Dahl ('98, '03) in his brief 

 outline of the history of ecology. Moller discusses 

 the influence of climate, soil, plants, animal sub- 

 stances and man upon insects, and the influence of 

 insects in the economy of nature. 



LORENZ, J. R. 



1863. Physicalische Verhaltnisse und Vertheilung der Or- 

 ganismen im Quarnerischen Golfe. pp. 379. Wien. 

 An early and important study of the habitat and the 

 plants and animals associated in the marine habitats. 

 Apparently but little known. Also not mentioned 

 by Dahl ('98, '03).
