Prof. Roland Thaxter has sent me a specimen of what may be E. electilis, Morrison, and says: “The Eutolype is, as I suppose, electilis, and is subject to very great variation as to the depth and disposition of the darker shades and the clearness of the maculation, some being more or less obliterate and others on the plan of Coelodasys biguttatus, var. cinereofrons.” This is the first specimen I have had, and I can only say it represents a species distinct from Rolandi or depilis. Unfortunately, the abdomen is missing, and I cannot say if it is tufted. The black dash described by Morrison is incomplete. I saw the type in the Tepper collection, but had no opportunity of comparing it with the others. It reminded me, on a very cursory examination, of muralis, but as all the species have the peculiar facies of the group, this comparison goes for nothing.
