on the abdomen and corium. Head black, highly polished, much wider than the front of 
nronotum, indented and grooved in front of the Carina of vertex, the carina sharp and 
hi"h- 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 united, the basal 
ioint much longer than the head and stouter than the second, ihe second .]oint 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 shi dng black, sometimes with a yellow line, 
tlie 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 stout spines, tarsi piceous at tip. Scutellum 
black moderately convex, transversely wrinkled, acute and pale at tip. Llavus duU 
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

^""^Le^^th 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 wiU have to be transferred to the genus Olobi- 
ceps Fiebr. Tliis species is common in the province of Quebec, and it occurs as far nort i 
as Great Slave Lake, in British America.”
