Khasis ; in May and June, twenty specimens. Closely allied to orthiodes, 
but the latter species is smaller and paler, and entirely without the dark fus- 
cous streak on palpi of @. Before recognising its distinctness I sent specimens 
of the present species under the name of orthiodes to some of my corre-
