170 U. S. NATIONAL MUSEUM BULLETIN 212 



Range : Tropical America, ? Africa. 



Species: About 50, of which 10 occur in our area. In addition to the 

 forms recorded below, BoUman listed Spirostreptus montezumae Saussure 

 (now referable to Orthoporus) as occurring in Texas at El Paso. As the 

 evidence makes it reasonably certain that the El Paso species is not the 

 same as Saussure's, O. montezumae is not cataloged herein.
