lonjj, extending well on to the base of the front. Front wide at the apex, 

 contracted between the eyes, sides almost parallel in the male, in the female 

 widened to below the middle. Antennte short, reaching the base of the 

 clypeus. Pronotum rather deeply concave behind. Elytra reaching the 

 middle of the abdomen in the female, equalling the abdomen in the male, 

 fork of the first sector longer than that of the second. Length, male 2 m.m., 

 female 3 m. m. 



Male: Dull brownish yellow, obscured behind the eyes and on the face, 

 with a clearer dorsal vitta from the vertex to the tip of the abdomen. Ab- 

 domen black, connexivum, two apical segments mostly, and the dorsal vitta 

 yellow. Elytra shining black with a narrow pale margin ; thighs lineated 

 with brown, the pectoral pieces obscurely spotted with the same color. 

 Pygofers short, truncated, viewed from behind broad, subtriangular, dorsal 

 notch deep, rounded, reaching the ultimate dorsal segment, ventral notch 

 shallow; stiles narrow, pointed, widely divergent, adjoining the ventral 

 margin lying almost horizontal. 



The female differs from the male in being of a duller color with the 

 black markings paler and less extended The venter is somtimes entirely 

 pale or touched with brown on either side. Oviduct black. Apex of the 

 pygofers truncated, their inner angle slightly exceeded by the stout oviduct ; 

 plates rather short and broad. 



Macropterous form : Elytra reaching for one third of their length beyond 

 the abdomen ; first sector widely forked somewhat nearer the base than the 

 second ; apical areoles seven, very irregular ; nervures punctate. Wings 

 whitish hyaline, nervures fuscous, the second white at base. 



New York. Described from one male and six female examples taken 

 near Buffalo from June iSth to July 31st. In form and ornamentation this 

 insect recalls genus Dicranotropis to which it is further allied by the elon- 

 gated apical fova of the vertex which extends well on to the base of the 

 front, where, however it is very narrow, but it can hardly be placed in that 

 genus. 



In dedicating this neat little Delphacid to my friend Mr. A. H. Kilman

 ciation as well of his scientific zeal as of his generosity in placing at my dis- 

 posal the many valuable Hemiptera captured by him in Southern Ontario.

Brachypterous form. Male: Vertex nearly square, passage to the front 

 well rounded, carinas feeble, especially on the forehead, fovte sometimes 

 obscure; front rather broad, oblong, scarcely contracted between the eyes, 

 sides feebly conve.\, apical margin straight; antennae stout; apex of the 

 scutellum abruptly subacute. Elytra narrowed and rounded at the apex, 

 reaching to the ultimate dorsal segment, the sectors equally forked. Pygo- 

 fers viewed from behind broad, rounded below, truncated above, sides a 

 little produced on the middle, the depressed margins rather wide below the
