68 THE CANADIAN ENTOMOLOGIST. 



Head depressed next the hind border, elsewhere tumid, smooth, 

 shining, blackish castaneous ; the labrum, neighboring parts and palpi 

 luteous, the basal joints of the outer maxillary pair obscured a little with 

 fuscous; antennae 14-15 jointed, luteous, a little tinged with brown 

 beyond the base. 



Pronotum as broad as the head, scarcely longer than broad, the sides 

 and posterior border scarcely convex, posterior angles rounded, lateral 

 edges a little marginate ; surface of the color of the head, scarcely paler 

 at the sides, slightly wrinkled, but otherwise smooth, flat on posterior 

 half and sides, the rest a little tumid ; a sharp median impressed line. 

 Tegmina of the same color, nearly twice as long as the pronotum, 

 slightly and broadly emarginate at the tip, slightly produced next the 

 inner edge. Exposed part of wings nearly half as long as tegmina, 

 honey yellow, with a broad inner and apical belt of dark castaneous, 

 almost or quite as black as the tegmina ; the extreme edge dull luteous. 

 Legs uniform honey yellow. 



Abdomen with nearly parallel sides in the male, a little convex in the 

 female ; dark, rich castaneous or mahogany brown, much obscured with 

 black, especially on the sides, at the incisures and down the middle, and 

 excepting the clearly colored terminal segment, distinctly punctate, less 

 deeply on the terminal segment ; lateral plications of second and third 

 segments rather slight ; last segment quadrate, twice as broad as long, 

 with parallel sides, depressed in a triangular space next the posterior 

 border ( ^ ), or tapering a litUe, with a median longitudinal depression 

 ( $ ), at the bottom of which is a slight longitudinal depressed line. 

 Pygidium of female hardly extended, moderate in size, quadrate ; of male 

 large, triangular, with laterally produced angles, and a more or less broadly 

 truncate apex, often laterally and concavely excised, the whole broader 

 than long. 



Forceps of female about half as long as the abdomen, simple, straight, 

 horizontal, incurved at tip, pretty strongly depressed, bluntly pointed, the 

 superior inner edge with a quadrate, laminate, depressed, blackened basal 

 tooth, much broader than long, and followed, after a brief space, by a 

 series of minute tubercles nearly to the tip ; inferior edge blackened, 

 minutely tuberculato-denticulate, the base largely and obliquely excised. 

 Forceps of male slender, nearly two-thirds as long as the abdomen, 

 horizontal, scarcely incurved, excepting at the rather bluntly pointed
