VAEJOVIS CAROUNIANUS Beanvois 

 SOUTHERN UNSTRIPED SCORPION 



Besides the common striped scorpion, Gentmroides vittatus (Say) 

 (pi. 2, fig. 5), there is another scorpion species somewhat smaller 

 that is found in many of the Southern States. This species, F. caro- 

 Unmnu^?, is unmarked, of a dark reddish brown, with a large post- 

 abdomen and rather slender pedipalps. A museum specimen meas- 

 ures slightly over 4 cm. in length. 



The species ranges from South Carolina to Texas. In the Na- 

 tional Museum collection there are specimens from Alabama, Georgia, 

 and Kentucky. Little is known about the habits of this species. 



VAEJOVIS SUBCRISTATUS Pocock 



This Mexican scorpion is of medium size (length 5.15 cm. male, 

 5.20 female, according to Pocock) and has the body mottled above 

 with reddish yellow and blackish brown. The first two segments of 

 the abdomen are broader than long. Pocock (1902) reports it from 

 San Andres and Jalapa, Mexico. The only United States record 

 that the writer has found for this species is by Borelli (1909), who 

 reports two young females from Tucson, Ariz., taken by Professor 

 Silvestri. 



VAEJOVIS SILVESTRII BoreUi 



Borelli (1909) described as new a scorpion taken by Silvestri in • 

 the Sierra Madre Mountains, Southern California. This appears 

 to be the only scorpion taken by this collector in a region rich in 

 described species. The species can not be satisfactorily placed, and 

 may be a synonym of one of the several species of Vaejovis known 

 from this region. 



Genus ANUROCTONUS Pocock 



In Anm'octonus the middle area of the pectines is broken up, 

 sometimes in an indistinct manner, into seven or less pieces ; and these 

 divisions are unequal. The sting is sometimes bulbous near the base. 

 But one species of the genus is known from the United States and 

 northern Mexico. 



ANUROCTONUS PHAIODACTYLUS (Wood) 

 SHINY-STINGED SCORPION 



Not only has this scorpion a shiny sting, but a most peculiarly 

 shaped one. Between the tip of the sting and the base, but nearer 

 the latter, there is an inflated, bulbous structure. Probably the term 

 " swollen-stinged scorpion " or " bladder-stinged scorpion " would be 

 equally appropriate with the one given at the heading of this para-
