Cyrtorrhinus marginatns Uhler n sp. 
“Long and narrow, black, moderately flat abj-ve, pale pubescent, bordered with green 
on the abdomen and corium. Head black, highly polished, much wider than the front of 
pronotum, indented and grooved in front of the Carina of vertex, the carina sharp and 
high; face almost vertical, the tylus prominent; eyes large, brown, prominent, placed a 
little obliquely, the border of their inner side pale yellowish; tylus, bucculae, and 
rostrum greenish-testaceous, the latter reaching upon the middle coxae, blackish at tip; 
antennae moderately stout, as long as the head, pronotum and corium unit* d, the basal 
joint much longer than the head and stouter than the second, The second joint as long as 
the clavus, the third more slender and about half as long as the second, the fourth still 
more slender and much shorter. Pronotum shining black, sometimes with a yellow line, 
the sides gradually contracting, rather strongly sinuated, the callosities large and 
prominent, the surface transversely wrinkled, convex posteriorly, longitudinally 
impressed near the humeri, the margin sometimes broadly yellow. Legs pale greenish, 
the tibiae dark at tip, the anterior pair with stouc spines, tarsi piceous at tip. Scutellum 
black, moderately convex, transversely wrinkled, acute and pale at tip. Clavus dull 
black minutely pubescent, corium dull black as far as next to the cuneus, also pubescent, 
broadly margined with greenish yellow, the cuneus mostly yellowish, the surface of the 
hemelytra granulate throughout; membrane long, smoke brown, with the veins pale 
yellow at tip. Middle line of the sternum and disk of venter pale greenish-yellow, finely 
pubescent. 
Length to tip of abdomen 4 mm Width of pronotum 1.25 mm. Only males of this 
insect have been brought to my notice. Should the female prove to be of the inflated 
type, with the spherical head, this insect will have to be transferred to the genus Globi- 
ceps Fiebr. This species is common in the province of Quebec, and it occurs as far north 
as Great Slave Lake, in British America.”

Diaphnidia Uhler n. gen. 
“Near Actorhinus Fab., elongate subelliptical, tender, opaque. Head gently sloping and 
curved anteriorly, the face almost vertical, a little longer than the width between the eyes; 
tylus projecting beyond the line of the face, curving bmeath, the upper bounding line placed 
nearly on the level of the lower end of eyes; eyes prominent, sub-rcniform, nearly vertical, with 
somewhat swollen neck behind their line; occiput with a carina sometimes arched in the 
middle, and with the surface flattened in front of it, cheeks diagonal, acutely narrowed at tip; 
gula almost horizontal, swollen at base; bucculae narrow and short, followed behind by a 
waved surface, basal joint of rostrum much shorter than the under side of head; antennae 
longer than the head, pronotum and corium united. Legs long. Pronotum trapeziform, with 
the lateral margins moderately oblique, the anterior margin forming a narrow, flat, sinuated 
colium; the transverse impressed line behind the callosities shallow. Hemelytra long and 
wide, contractingly curving towards the base, semi-diaphanous, with a sharply reflesed costal 
margin ; cuneus large and long, with the outer border reflexed. Abdomen very narrow.” 
Diaphnidia debilis Lhler n sp. 
“Delicate green, or greenish-white, indistinctly and very minutely pubescent around the 
sides of head, pronotum and beneath. Head a little grooved on the middle line, and a little 
callous each side between the eyes; antennae yellowish, the basal joint much longer than the 
head, thicker than the second joint and contracted at base, the second of uniform thick¬ 
ness throughout, as long as the outer margin of the corium; rostrum yellowish, black at tip, 
reaching between the anterior coxae. Pronotum wider than long, almost flat on the disk, 
gently sloping, with the surface a little wrinkled, the lateral margins a little sinuated in front 
of the prominent humeri; the anterior submargin occupied by the transverse ridge of the almost 
contiguous callosities. Legs pale green, more yellow upon the tibiae, upon which the spines are 
dark, and the base and apex of the tarsi piceous. Clavus, corium and cuneus minutely, 
remotely and obsoletely scabrous. Abdomen silvery greenish. 
Length to end of abdomen 3 33 mm. To tip of membrane 5.5 mm. Width of pronotum 
1.5 mm. Two males from Colorado are the only specimens 1 have seen.”
