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.
