than the basal width or the length of the pronotum. Face in profile 
straight, deeper than in mollipes , clypeus larger and more strongly 
angled. Pronotum broad, side margins long. Elytra strong, vena- 
tion as in mollipes . 
Color; as in mollipes. Pronotum and elytra deeper green, the 
nervures paler. Lines on vertex broad and distinct, black lined, 
extending back of the eye and margining the reflexed 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, 
rfche 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, Ohio 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, Pig, 5. 
Form of novaeboracensis nearly, with a longer head, as 
long as in 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 flit 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. 
Pronotum small, elytra and venation as in mollipes. 
Color; deep green as in angulifera ; vertex washed with green. 
Female with a light band around the broad margin of fhe vertex; 
inside of this on either side are five concentric lines, the rest of the 
markings as in angulifera. 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
