Class INSECTA. 



Order ORTHOPTERA (continued). 

 Fam. ACRIDIIDJE*. 



The family Acridiidse among the Orthoptera is one of the most extensive and 

 important groups of insects belonging to the order. Although considerable attention 

 has already been devoted to them by entomologists, they remain little known when 

 compared with the other related families. This is perhaps largely due to the fact that 

 Dr. H. de Saussure, our most active worker in Orthoptera during recent years, has 

 devoted bis energies to the Blattidae, Mantidse, Gryllidae, and Locustidae. It is also 

 quite probable that the material difference in haunts and habits among the various 

 species of locusts, as compared with the insects belonging to the families just named, 

 renders them less conspicuous. This being the case, the general collector passes many 

 forms by when otherwise he might have observed and taken them. 



Although the material submitted to the writer by the Editors is less complete than 

 could be desired, this deficiency has been in a measure made good by the study of 

 a number of public and private collections. Especially deserving mention are those 

 of the United States National Museum, the California Academy of Sciences, the 

 American Museum of Natural History in New York, and the Museo Nacional, 

 Tacubaya, Mexico. Of the private collections, those furnished by Dr. Henri de 

 Saussure, of Geneva, Switzerland; Samuel H. Scudder, Cambridge, Massachusetts;
