122 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



Jn discussing this paper Mr. Caudell spoke of the Mantid genus 

 Brunneria. This genus was described by Saussure in 1869 from a 

 species from Argentina and within the next two years he added two 

 more species, both from Brazil. A quarter of a century later Mr. 

 Scudder described B. borealis from Texas in the United States. 

 Representatives of this genus have never been found in the inter- 

 vening countries of Mexico and Central America, though future 

 collecting may yet show the genus to occur there. The northern 

 species, five speciments of which are in the National Museum Col- 

 lection, have been compared directly with the type species from 

 South America and appear to be perfectly congeneric with it. 



Accidental introduction was cited as a potent factor in discon- 

 tinuous geographical distribution. It was suggested that had the 

 recently introduced Asiatic mantis, Tenodera sinensis, been brought 

 over by some early explorer it might have become jWell distributed 

 over our northeastern states and have been described by some early 

 American entomologist as a new species, its relationship to the Old 

 World form not being suspected. Indeed, in a case like this, were 

 the known New World four thousand or more 3 r ears old instead of 

 four hundred, the species would very likely have been changed by 

 climate and environment into a distinct variety or species or even 

 genus. 



In reply to Mr. Caudell, Mr. Banks said it made no difference 



whether these genera were used in the present sense or divided; the 

 fact would still remain that one genus or several allied genera had a 

 certain distribution. He also said that though there were many 

 insects distributed by commerce, the distribution of the genera he 

 had considered was effected long before the existence of man.
