Pundaloya {Green). 



A common Indian species. 



Fabricius places this species between Orthetrum caneellatum 

 and Sympetrum pede^nontanum. There is nothing in the descrip- 

 tion to fix the species positively; but if, as is moat probable, 

 Fabricius intended to. compare the insect with O. caneellatum, 

 then I think my identification is most probable. De Selys 

 identifies L. carnatica with Trithemis f estiva (antea, No. 16).
