exceeded by the elytra; ultimate ventral segment of the male abdomen 
very short, nearly four times wider than long, convex, the posterior angles 
produced, style like; plates subquadrate, rounded behind. 
Habitat: Specimens are at hand from Ontario, New York, 
New Hampshire, District of Columbia, Maryland, and West 
Virginia, and it has been reported from Ontario, and Walker’s 
species were from Nova Scotia and Florida. 
Readily separated from 'parallela by its shorter vertex and 
smaller front, as well as its smaller size and lighter color;" 
from signoretii, which it more closely resembles, by the light 
stripe and the male genitalia. 
APHROPHORA ANNULATA n. Sp. 
Light ochraceous-brown, irregularly maculated with chest- 
nut, lighter colored and more heavily marked than saratogensis, 
with a shorter female ovipositor and narrower, divergent male 
plates; length 10-1 1mm., width 3.5-4mm. 
Vertex, flat, sloping, strongly angularly emarginate behind, roundingly 
angulate in front, scarcely longer in the middle than against eyes, anterior 
margin very thin either side tylus, tylus very broad and short; front 
moderately inflated, about equaling long diameter of eye, slightly anter- 
iorly produced, forming very nearly a right angle with the vertex; pro- 
notum strongly depressed on the anterior half, then suddenly elevated and 
rounded on the disc, the lateral margins short, sharp and oblique, scarcely 
as long as the distance between the ocelli, elytra moderately long, some- 
what inflated, the costal margin reflexed anteriorly. 
Color: Vertex, ochraceous, with a faint, median light line, bordered 
by two broad chestnut ones; pronotum pale, ochraceous, a chestnut stripe 
arising just before the middle on either side the carina and running back- 
ward, and then obliquely outward and broadening to the claval 
margin; disc of scutellum chestnut, the margins pale, elytra pale, ochra- 
ceous, an area at the base, an oblique band from the scutellum, broadening 
to just before the middle of the costa, another before the apex of the clavus 
and the nerve at the base of the apical cells, deep chestnut. 
Genitalia: Female pygofers convex, scarcely longer than wide, ovi- 
positor short and stout; ultimate ventral segment of the male abdomen 
nearly twice wider than long, subcylindrical; plates broad at the base, the 
outer margins flaring, inner margin cut off obliquely nearly to the base, 
slightly sinuate, leaving two widely divergent, black-tipped points. 
Described from sixteen examples labeled ‘^Wasatch, Utah, 
6-27-91, ” received through the kindness of Mr. Otto Heide- 
mann. Easily separated from permutata^ which occurs in the 
same region, by the lighter color and heavier marking, as well 
as by the very distinct genitalia.
