Australian Scorpions of the Genus Urodacus, Pet. 59 



basin macula obliqua fusco-nitida notatis ; anteunis ( $ ) corporc 

 longitudine sequalibus. 

 Long. 10, lat. 3| millim. 



Hob. Samburu, Brit. E. Africa (G. 8. Betton). 



Reddish brown, clothed with fulvous pubescence and with 

 long erect setas. The pubescence on the prothorax, on the 

 sutural borders of the elytra from a little behind the base 

 almost up to the apex, and on a lateral plaga behind the 

 middle of each elytron is of an ashy-grey colour. Each elytron 

 has an oblique nude spot near the base, the derm of this spot, 

 as well as beneath the ashy-grey areas, being black in colour, 

 whereas on the remaining parts of the elytra it is reddish 

 brown. The elytra are strongly and somewhat thickly 

 punctured, the punctures being irregularly spread, except 

 along the middle, where two more or less regular rows may 

 be distinguished. 



Sophronica testacea, sp. n. 



Testacea, subnitida, dense profundeque punctata; antennis ultra 



medium infuscatis. 

 Loug. 9, lat. 3^ millim. 



Hah. Mpwapwa, E. Africa (Dr. Kirk). 



Head and pronotum reddish testaceous ; elytra, legs, and 

 underside yellowish testaceous. Head, pronotum, and elytra 

 thickly and deeply punctured, with the punctures of the 

 elytra rather larger towards the base, and gradually diminishing 

 in size towards the apex. 



This species agrees pretty closely in structural characters 

 with S. carbottaria, Pasc, but is relatively somewhat broader 

 in form ; the eyes arc larger, with the upper lobes more 

 approximate, and the scape of the antennas is a little shorter 

 and more thickened towards the apex. In colour it somewhat 

 resembles 8. calceata, Chevr., which is, however, a relatively 

 narrower and more elongated species, having longer and more 

 slender antennas. 



V1IJ. — The Australian Scorpions of the Genus Urodacus, Pet. 

 By K. I. Pocock. 



The genus Urodacus is the sole member of the family Scor- 

 pionidse which is confined to Australia. It may be readily 

 distinguished from the remaining members of the order that 

 occur in this area by the possession of the following features: —
