Pectinal teeth $ 16-17, $ 21-29. 



Length up to 35 mm. 



Locality. — Upper Scinde, Khelat Frontier {Types) and Kashmore 

 Bund (A. V. Kemball) ; also a single example from Haidarabad, Scinde 

 (G. M. By an). 



Resembling the Persian B. melanurus, Kessler, and the Transcaspian 

 B. conchini, Sim., in having the terga unicostate, but differing from 

 both in being entirely pale coloured, instead of deep green, and from 

 B. melanurus in having the lower surface of the fourth and fifth* seg- 

 ments granular, and from B. ccnchini, which it appears to resemble in 

 having the lower surface of the fourth and fifth segments rugose 

 (granular), in having the legs and upper side of the tail granular.

Very closely allied to B. pallidus, which it resembles in colour, 

 except that the tergal plates are infuscate, but differing in having the 

 tail much smoother. For example, the inferior keels on the first 

 segment are smooth and the fourth and fifth segments are scarcely 

 granular below, though very coarsely punctured. 



Pectinal teeth $ 20. . 



Length about 28 mm. 



Locality* — Karagora in Kathiawar (H. Bulkley). 



Genus Aechisometeus, Kraepelin. 

 (9.)— Archisometrus crassimanus, sp. n. 



Colour. — Blackish-brown without any very distinct yellow pattern, 

 tail paler ; vesicle and hands of the palpi and distal segments of legs 

 clear yellow ; basal segments of legs and palpi blackish. 



Carapace.— Somewhat finely granular; its anterior border somewhat 

 coarsely so. Terga conspicuously, though not very coarsely, granular 

 in the posterior half, the posterior border of the carapace and of 

 the first and second terga tri-emarginate ; the terga conspicuously 

 tricastate (the first obsoletely so) ; sterna smooth and punctured, the 

 last almost without crests and without granules, merely faint traces 

 of two of the crests. Tail of medium length and thickness, less than 

 four times the length of the carapace, the median lateral crest weak 

 on the first, but represented by a posterior series of granules on the 

 second and third ; the keels denticulate, the intercarinal spaces sparsely
