Seaphoideus sanctus Say. 



Seaphoideus picturatus Osborn Proc. la. 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 onl}' 

 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 forni to occur in Southern 

 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 valle}' 

 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 ver}' closely the fasciatus described from Haiti, but as 

 stiggested by Van Duzee 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 fonn. Say's statement " feet immaculate " applies 

 better here than to the other fomi though there are black points on 

 the tibia. The localities for this species will now stand as Indiana, 

 (Say), Iowa (Osborn), Missouri, (Riley), Kentucky, (Gannan), 

 Illinois, Metropolis, "River," C. A. Hart, 3 females, 3 males, in 

 111. State 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
