This species is somewhat near Rev. O. P. Cambridge's E. benevola from 

 Yarkand (Yarkand 2nd Mission, Pt. viii., Arach p. 95). He does not mention 

 the size of his specimen, but this would appear to differ from it in the darker 

 colour of the whole of the pars cephalica, the lighter median area not passing 

 thereto, the clypeus not so broad as twice the front median eyes, paler lip and 

 darker sternum. There are no cretaceous white spots on the abdomen, the 

 median longitudinal marking only reaches half way, and there is no 

 longitudinal band or other marking on the underside. 



I have named it after Capt. Douglas, V.C., D.S.O., R.A.M.C., the 

 collector of all the specimens brought home.
