Genus SCAPHIOSTREPTUS Brolemann 



Scaphiostreptus Brolemann, 1902, Rev. Mus. Paulista, vol. 5, p. 152 (as 

 subgenus of Spirostreptus) . 



Scaphiostreptus Attems, 1914, Zoologica, vol. 25, Heft 65-66, p. 75; 1950, 

 Ann. Naturh. Mus. Wien, vol. 57, p. 225. 



Generotype : Spirostreptus fuscipes Porat, by present designation. 



Range: Tropical America, from southern Brasil north to Texas. 



Species: About 40, only one of which is known with certainty to occur 

 in the United States. One or more other species, among the several based 

 upon females and here placed under Orthoporus, may belong to 

 Scaphiostreptus. 



Scaphiostreptus Jexicolens (Chamberlin) 



Orthoporus texicolens Chamberlin, 1938, Proc. Biol. Soc. Washington, 



vol. 51, p. 207. 

 Type: Collection of R. V. Chamberlin. 

 Type Locality: Edinburg, Hidalgo County, Texas. 

 Range: Southern Texas. 



Spirostreptidae of uncertain systematic position 



Spirobolus miles Chamberlin 



Spirobolus miles Chamberlin, 1918, Pomona Coll. Joum. Ent. and Zool., 

 vol. 10, p. 11, 



Type: Mus. Comp. Zool. 



Type Locality: Fort Boutelle, Arizona. 



Range : Known only from type locality. This species is clearly a spiro- 

 streptoid, but its correct generic position cannot be determined in the ab- 

 sence of males. 



Julus multiannulatus McNeill 



Inlus (sic) multiannulatus McNeill, 1887, Proc. U. S. Nat. Mus., vol. 10, 

 p. 331. 



Type: Location unknown. 



Type Locality: Fort Madison, Lee County, Iowa. 



Range: Known only from the type locality. This is rather considerably 

 out of the known range of spirostreptids in this country, and since none 

 have subsequently been found near Iowa, there is some doubt about the 

 provenance of the type specimen.
