than the basal width or the length of the pronotum. Face in profile 

 straight, deeper than in jno/Zipes, clypeus larger and more strongly 

 angled. Pronotum broad, side margins long. Elytra strong, vena- 

 tion as xnmollipes. 



Color; as xvyvtollipes. Pronotum and elytra deeper green, the 

 nervures paler. Lines on vertex broad and distinct, black lined, 

 extending back of the eye and margining the rettexed portion of 

 front half way to the apex, a line along the margin from the suture 

 to the eye, curving in to form a spot on the disc inside the eye. 

 Face pale yellow, about nine short arcs on the sides of front, a spot 

 on genae and a dot on the outside the lorae, black. Below usually 

 pale, a line running back from under the eye black, sometimes all 

 below this line clouded with fuscous. 



Genitalia; female segment with the posterior margin rounding, 

 the apex slightly, angularly produced, pygofers long and narrow. 



Male, ultimate segment longer than wide, cylindrical, from the 

 open end of which appears a semi-circular valve and a pair of long, 

 strong, slightly, divergent, pincer-like plates, longer than the long 

 ultimate segment, their tips curving upwards and inwards. 



Specimens have been examined from New York, Penn- 

 sylvania, Otiio and Iowa and Walker described it from 

 New Foundland, and it has been reported from Canada 

 and*Kansas. The strikingly large size, especially of the 

 female, will at once separate this species. The male 

 genitalia is also very distinct. 



Draeculacephala manitobiana n. sp. Plate VII, Fig. 5. 



Form of novaehoracensis nearly, with a longer head, as 

 long as i^angulifera, but much narrower. Color as in the 

 latter species, the males often with a black wedge and a 

 pair of ovals on disc of vertex. Length, 9 8-9 mm., <? 7-8 

 mm.; width, 2 mm. 



Vertex one-fourth longer than the pronotum, as long as its basal 

 width, disc flat the margins thick, slightly but distinctly rounding. 

 Face moderately deep, profile convex or slightly angled before the 

 clypeus, which is gibbous and gives a second angle to the profile. 

 Pronotnm small, elytra and venation as in niollipes. 



Color; deep green as \xi^angulifera\ vertex washed with green. 

 Female with a light band around the broad margin of the vertex; 

 inside of this on either side are five concentric lines, the rest of the 

 markings as in'^ngulifera. Spots at the apex rather large, sepa- 

 rated by an elongate ivory white mark. Front with ten pairs of 

 rather long arcs and a median line fuscous, a black mark above the 

 antennae and a dot outside the lorae. The male has a large tri- 

 angular spot behind the apex of vertex and the broadened lines on 

 the disc, black, the lines often becoming confluent and forming an
