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 paraZZe^a 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. 



6 APHROPHORA ANNULATA n. Sp. 



Light ochraceous-brown, irregularly maculated with chest- 

 nut, lighter colored and more heavily marked thsknsaratogensis, 

 with a shorter female ovipositor and narrower, divergent male 

 plates; length 10-llmm., 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 

 I'ounded 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.
