In Ann. & Mag. Nat. Hist. May 1888, pp. 335-338, I pointed 

 ont the occurrence o^ Scolopendra valida, a Canary Island species, 

 in Socotra and Bushire. The British Museum has subsequently 

 received examples from S. Arabia, and I think the following 

 subspecies may be recognized. 



Subspecies deseeticola, nov. 



Head, antennae, first tergite, and maxillipedes deep green ; 

 trunk olivaceo-castaneous, with the posterior border of the terga 

 banded with green. Legs entirely flavous. 



Log. Shehu. A single specimen, measuring 125 mm. in length. 



The Museum has received specimens of the same subspecies 

 from Aden (^S*. B. Shopland) and Muscat {A. G-. JayaJcar). It 

 seems to extend, therefore, over the whole of S. Arabia. 



On the other side of the Persian Grulf, i. e. at Bushire and 

 Jask, there appears to be another type of this Centipede, which, 

 may be called Scolopendra valida subspecies persica, nov., and be 

 diagnosed as follows : — Head and antennae deep green; distal ends 

 of th.e anal legs also deep green ; terga flavous (Bushire ; 

 3 examples, 113 mm.). Two examples from Jask, 118 mm. in 

 length, resemble those from Bushire, but four others have the 

 anal legs quite green and some of the anterior terga bordered 

 with green. Specimens of this subspecies from .Ta>^k have been 

 received from Mr. B. T. Ffinch and Mr. Butcher. 



A third subspecies may be recognized as S. valida subsp. 

 Balfouri, nov. The young are entirely pale, but in adult speci- 

 mens, which may reach a length of 190 mm., the head, antennae, 

 and all the legs are green, or even black, and although the 

 posterior halt of the trunk is paler, the anterior half is distinctly 

 olivaceous or olivaceo-castaneous.
