Color: Vertex, grayish-brown, anterior margin of tylus black-lined, 

 rest of margin light, except against the dark eyes; ocelli red; median 

 carina light: pronotum grayish, the carina and a spot on either side before 

 the middle pale: elytra with the claval areas pale, grayish, corium darker, 

 an oblique hyaline band before the middle, extending from the costal 

 margin to the inner sector, sharply margined behind, fading out in front, 

 behind the middle is an elongate hyaline spot: between these spots is an 

 irregular, dark-brown area, and in well marked specimens another 

 appears in front of the band and a third behind the spot. 



Genitalia: Female pygofers about one-third longer than wide, slightly 

 exceeded by the ovipositor; two last segments of the male abdomen 

 elongate narrowed; plates small, twice longer than wide, separated at the 

 base by their own width, their inner margins parallel, outer rounding. 



This is the most abundant of the eastern species and is 

 readily recognized by its small size and white markings. A 

 series of several hundred examples show little variation in 

 size or color. 



Habitat: Examples have been examined from Ontario, 

 New York, New Hampshire, District of Columbia, Maryland, 

 West Virginia, Georgia, Florida, Iowa and Nebraska, and it 

 has been reported from Ontario, Maine, Massachusetts, Ohio, 

 Illinois, and North Dakota. 



O APHROPHORA ANGULATA n. sp. 



A. angulata Uhl. Mss. 



Pale, nearly uniform grayish-brown, two obscure hyaline 

 spots along the costa; larger and more obscurely marked than 

 o ^-notata; length 10mm., width -Imm. 



Vertex flat, scarcely longer on middle than next to eye, anterior margin 

 sharp as far as the tylus, which is slightly produced upon the front: 

 median carina weak on the tylus, becoming strong on the posterior margin 

 of the vertex; front weakly inflated, forming an acute angle with the 

 vertex as in Jf-notata; pronotum, anterior third depressed, finely punctate, 

 with a sti'ong median carina, behind this, elevated and coarsely pitted, 

 with the carina weak; elytra very broad in the center, roundingly angulate 

 behind; the costal area attaining the center of the corium at the angle of 

 the first sector. 



Color: Grayish-brown; vertex and anterior third of pronotum brown, 

 with the fine punctures black, median carina light, rest of pronotum light, 

 with dark pitting: scutellum light-gray; elytra, ground color light, 

 coarsely pitted with brown, becoming darker on the middle of the costa, 

 either side of which there is a large subhyaline area, nervures mostly 

 dark margined and distinct. 



Genitalia: Female pygofers scarcely half longer than wide, moderately 

 exceeded by the short ovipositor.
