California. C. nigrescent, a variety of the more south- 

 ern C. gracilis, has been reported from Texas. Four 

 species occur in Florida, but of these C. gracilis and C. 

 margaritatus belong to a more southern fauna, the latter 

 being the most common scorpion of Mexico and Central 

 America. One species, C. iufamatus, has practically the 

 same distribution as Vejoris rarolinus, spreading north- 

 ward into South Carolina and southward into Texas and 



northern Mexico. C. iiifanwtus is the common scorpion 

 of the southeast and south. Several other species of Cen- 

 trums are characteristic of tropical North and South 

 America.
