KASHMIR, 6000-7000 ft, r.Ol (CoL Nurse); BENGAL: Pusa ; 

 CENTRAL PROVINCES : Xagpnr (Pusa coll.) ; BOMBAY: Surat, i. 04 

 (Pusa coll.), Poona, viii.86 (It. C. WrougJiton, type). 



Type, in the British Museum. 



It is closely allied to B. orientalis. and the divergences are little 

 more than omissions in Cameron's description ; the abdomen is 

 more broadly flavons and the fourth segment in particular, the 

 hind tibiae are basally black and centrally white, and the rnetanotal 

 areola is entire and very distinct. From B. tricinctus, Grav., it 

 differs in its stouter and more compact form, the greater convexity 

 of tbe abdomen, and the much broader segmental fascia;. 



The species is probably not uncommon in Bengal, where Mr. 

 Maxwell Lefroy has bred it (as he believes) from the sawfly, 

 Athalia proxima, Klug, on 8th December, 1906, and both sexes 

 from (more correctly, doubtless) SyiyJnis ceyyptius, Wied., at 

 Surat.

GENOTYPE, Bassus tarsatorius, Panz. 



This genus is instantly distinguished from Bassns, as here 

 restricted, by the lack of transverse impressions on the basal 

 segments, its more slender conformation, and more nitidulous 

 tegument. From the other genera of the BASSIDES it will easily 

 be recognised by Ihe small and immaculate metathoracic spiracles,, 

 simple scutellar fovea, punctate and more or less dull face, which 

 is not distinctly impressed longitudinally, the obsolete notauli, 

 not deeply excised scape, and by the hind tibiae having no sharply 

 denned white central cincture. 



Range. Palaearctic and Nearctic Regions. 



At least thirty-five Palfearctic species of this genus are now 

 known ; but only three from America have elsewhere been described. 

 Our present knowledge is limited to a single Asian species, which 

 has been erroneously described as new by Cameron, and three 

 others that I have seen in collections.
