Genitalia: Female last ventral segment almost one-half longer 

 than penultimate. Posterior margin with narrowly rounded and prom- 

 inent lateral lobes ; broadly emarginate from these to a rather broad 

 central lobe which is distinctly sinuate at the middle. Ovipositor dark 

 in color. Male valve more than twice as long as preceding segment, 

 gradually narrowed either side from base to roundingly produced apex. 

 Plates longer than valve, half as broad as long. Outer margin undu- 

 lated, inner margins overlapping toward apex and convexly curved to 

 outer apical margins. 



Described from one female and two males from Clarksville, 

 Tenn., collected August 7th, and a single female from Ulster 

 County, N. Y. Kindly loaned by Dr. Herbert Osborn. Type, 

 male specimen in author's collection. 



This is different from any of the species described, so far as 

 I can determine from descriptions and authentically identified 

 specimens of most of the nearctic forms. 



Aligia modesta (O. & B.). 



Four specimens were taken during July, 1917, at Clarksville. 



Scaphoideus carinatus Osb. 



Three specimens from Clarksville, July 26, 28 and 29. 



Scaphoideus cinerosus Osb. 



Two specimens, Clarksville, July 13 and 16. 



Scaphoideus opalinus Osb. 



Five specimens swept from grasses in pasture land at 

 Clarksville, July 13 and 23. 



D Otocephalus alboneura n. sp. 



Resembling D. vinnulus Crumb in size and general appearance but 

 with more conically produced head, distinctive coloring and genitalia. 

 Length, 2 mm. 



Vertex conically produced, twice as long at middle as next the eye, 

 and slightly longer than width between the eyes. Pronotum longer than 

 vertex, twice as wide as long, rather strongly produced on anterior 

 margin. Elytra scarcely longer than abdomen, with reticulations on 

 the clavus and middle antiapical cell divided. 



Color: Face fuscous, marked with pale arcs and fading to dirty 

 yellow above. Vertex dirty yellow with dark median impressed line on 

 posterior two-thirds, a pair of spots at the apex, two either side along 

 margin between these and the eyes, the inner one lying close to the eye, 

 dark fuscous. A transverse fuscous band interrupted at the middle 

 crosses the disc of vertex between anterior margin of eyes and termi- 

 nates in a spot next either eye. Two oblique dashes either side of
