Da^cription . — Grayish yellow, variegated with brown and tinged with rod 
on scutellum, iironotuin posteriorly, and disc of abdomen; antennae darker 
in apical half, the second and third segments narrowly pale at apex, the second 
broadly and indefinitely pale at middle; pronotnm except explanatc margins 
sometimes almost black; connexivnm with a dark marginal si)ot at l)ase of 
each segment; tergum with a series of dark spots, each shared by adjacent 
segments and situated mostly within connexival suture; disc of sixth abilomi- 
nal and dorsal genital segments dark, the latter with a narrow, median, i)ale 
strii)e; genital lobes with narrow dark margin in lateral halt; hemielytra 
dark Iirown, veins of corium paler; legs yellowish with irregular dark spots, 
tibiae i)ale at ajx'x. 
I lead longer than broad (40 to 34), longer than pronotnm (40 to oO), 
tylus large, slightly l)ulbous; imjiressions of vertex narrow, jiarallcl, close to 
eyes, between them two rows of pale granules diverging anteriorly; ])reocular 
tubercles very distinct; antenniferous spines slender, divergent, with distinct 
lateral tooth, suddenly broader at l)ase; antennae (fig. 25c) slender, almost 
as long as head and pronotnm together, the first segment not reaching middle 
of tylus, the second in length more than efpial to width of head including 
both eyes (30 to 31); rostrum extending slightly beyond middle of meso- 
sternum. Pronotnm (fig. 25d) distinctly convex before and behind trans- 
verse depression; lateral margins slightly reflexed, strongly ex])anded to 
anterior angles, with large teeth; carinae well elevated. Scutellum longer 
than lu-onotum (40 to 30), sides slightly curveil from I)ase to rounded apex 
and a little elevated; basal portion of disc somewhat elevated and bearing 
three longitudinal carinae. Hemielytra (cf) reaching genital lobes, corium 
to apex of fourth at connexival suture; ( 9 ) extending to middle of sixth 
abdominal segment, the corium to middle of fourth; connexivum broadly 
exposed; exocorium moderately ex])anded, the dilation elongate; meso- 
corium with one, endocorium without distinctly developed transverse veins. 
cf (fig. 25b). Sixth ventral segment longer than filth, angulately emargi- 
nate posteriorly; genital segment short, strongly convex, the lobes rather 
short; aljdomen oval, margins crenate at sutures. Lc'ugth, S.7 mm. 
9 (fig. 25a). Dorsal genital segmeitt truncate at ai)ex; abdomen elong- 
ate oval, margins slightly crenate at sutures. Length, 9.75 mm. 
Type specimen (\'anconver Island, British Colmnbia) in \ an 
Dnzee’s collection. 
This is a rather brightly marked species, related to (lebtlis, 
from which it is to be distinguished by the color of the antennae, 
shape of pronotnm, and genitalic structure.
