margins black beyoiul the apical angle of the eyes; sides of the head to 

 the lower line of the eyes and the clypeus black; antennal base soiled 

 yellowish white like the vertex. Pronotum rather obtnsely angnlarly 

 einarginate behind, strongly produced before, the narrow apex trun- 

 cated before between the eyes; carinae strong, the lateral straight and 

 almost reaching the hind margin; color black, a little piceous between 

 the carina?, the dcflexcd sides edged with white below. ]\Iesonotum 

 black, opaque, the carinae distinct at base, becoming obsolete, the 

 lateral at the middle, the median beyond the middle; metanotum 

 apparently rufous. Elytra narrow, but little expanded at base, 

 appendix broad ; color black, nervures mostly pale, areoles except along 

 the costa and on the appendix dotted with pale, mostly in a single row 

 in each areole; stigma concolorous. Wings deep smoky brown with 

 fuscous nervures. Sternum black anteriorly, pale posteriorly and 

 about the coxae; propleurac edged with white above. Anterior and 

 intermediate legs black, posterior brown. Abdomen sanguineous, 

 perhaps somewhat fuscous above; apical pieces paler edged with black. 

 Sides of the genital segment of the female feebly arcuated, not at all 

 sinuated. Length 8 mm. ; width across the elytra scant 3 mm. 



Described from one female example swept by me from bushes on a 

 wooded hillside at Gowanda, New York, August 7, 1907. This is a beau- 

 tiful addition to our Fulgorid fauna. Its strongly produced head, white 

 front, sanguineous abdomen and narrower and blacker elytra, wanting 

 the stigmatal spots, will at once distinguish this from opaca. The 

 elongated head seems to ally this species with genus Pseudohelicoptera 

 Fowler, but by itself does not seem to warrant the establishment of a 

 separate genus. Fowler's species probably is not congeneric with this. 



Heliooptera pallida Say. 



Mrs. Slosson has sent me specimens of this species and septcntrionalis 

 Prov. from the White Mountains that show them to be sufHciently 

 distinct. Pallida is proportionately broader than any of our other 

 described species; the vertex is about as long as broad, being longer 

 than in variegata; the elytra are very pale brown, closely irrorated and 

 reticulated with pale, these colors being about evenly divided; there 

 are a few larger brown spots, about two on the disk of the corium and 

 three toward the apex, the latter somewhat broken by the pale nervures. 

 The front is pale with its base abruptly, and the clypeus brown. This 

 pale color is extended along the sides of the pleurae and is bounded 

 above with black. Abdomen mostly fuscous; metanotum rufous.
