Scaphoideus intricatus Uhl. 
Additional records for this species have been secured for 
Columbus, Ohio, taken on clover in September, 1909; at Akron on 
Comus, September, 1909, and a record from Professor H. Garman 
for Lexington, Kv., September 20, 1909, on cultivated grape, also 
from Franconia, N. H., by Mrs. Slosson. The original description 
referred this species to Crataegus, but it has been taken on so 
many different plants and in some cases so remote from this tree 
that it is uncertain as to its normal food plant. So far as I know 
the larvae have not been seen, and consequently the food habit as 
determined by the larvae is uncertain. The species is now known 
to range from Kansas and Nebraska to New Hampshire and south 
to Virginia and Kentucky. 
Scaphoideus ochraceus Osb. 
Further records showing distribution of this species have 
been secured since the publication of my paper in 1900, for Dur- 
ham, N. H., Buffalo, N. Y., 1907, and Ohio Pyle, Pa., Aug. 10, 
1905. It must undoubtedly occur in Ohio, but so far has not 
appeared in collections. 
Scaphoideus productus Osb. 
This species has been recognized at various localities, espe- 
cially to the south. I have records for Balsam, N. C., at altitudes 
of 4500 to 5000 feet, from the Department of Agriculture of North 
Carolina, and have also seen specimens collected at Tryon, N. C., 
by Mr. Fiske. Mr. Barbour has sent me a specimen from Cold 
Spring Harbor, L. I., so the species is pretty well distributed from 
Onaga, Kansas, Sioux City, la., east through Kentucky into 
North Carolina, and north to New York. 
Scaphoideus carinatus Osb. 
This species has been recorded from Cold Spring Harbor, 
L. I., (Barbour) and Black Mt. (Beutenmueller) Tryon, N. C. 
(at light) from Fiske, Little Mt., Ohio, in addition to the previous 
records. So far no specimens have been obtained from western 
localities, so that it appears to belong to the Atlantic region from 
New Hampshire to North Carolina, and west to eastern Ohio at 
least. 
Scaphoideus nigricans n. sp. 
Closely related to immistus, but much darker and with the 
female genital segment longer, and with a polished produced 
hinder border. Length 5.5 mm. 
Vertex about twice as long at middle as next the eye, rounding to a 
distinct obtuse angle at the tip; front rather narrow, sloping uniformly to 
the clypeus which is distinctly widened apically; lorae large, touching the 
border of the cheek; pronotum distinctly emarginate behind; elytra trans-
