Scaphoideus sanctus Say. 
Scaphoideus picturatus Osborn Proc. Ia. Acad. Sci. V, p. 243, (1898). 
The original description for this species was based on speci- 
mens from Indiana, but no type specimens exist. The only 
species which has been secured from this region in recent years, 
agreeing with Say’s description, is the one which I described under 
the name picturatus from material collected in Iowa and Kentucky. 
Recent collections have shown this form to occur in Sottthern 
Ohio and at other points in the Ohio valley, but it has not been 
taken on the Atlantic slope nor in the Gulf States. Since the 
form hitherto known under the name sanctus, following Van 
Duzee’s reference in 1894, has never been found in the Ohio valley 
nor outside of the Atlantic coast or Gulf States, there seems 
abundant reason to make the change suggested in my former 
paper and to recognize the Ohio valley form as sanctus. With 
this change the form occurring on the Gulf coast and which has 
the broad black band across the face remains undescribed. It 
resembles very closely the fasciatus described from Haiti, but as 
suggested by Van Duzec differs from that form in size and details 
of head, so that it seems best to recognize it as a distinct species. 
(See neglectus, poste.) 
The sanctus of Say has a somewhat more pointed vertex, and 
the front is entirely without the black band which is so conspic- 
uous in the other form. Say’s statement “ feet immaculate ” applies 
better here than to the other form though there are black points on 
the tibia. The localities for this species will now stand as Indiana, 
(Say), Iowa (Osborn), Missouri, (Riley), Kentucky, (Garman), 
Illinois, Metropolis, “River,” C. A. Hart, 3 females, 3 males, in 
111. vState Lab. Natural History, and Ohio, (Osborn), the localities 
in the latter state being Marietta and Portsmouth. Practically 
all of these records are based upon single specimens, which indi- 
cates a distinct rarity for the species. The specimen I took at 
Marietta was found on willows or vegetation close to them, but
