? 
Elongate ovate; upper surface yellowish or grayish, thickly, irregularly 
punctured with reddish or fuscous. Head long, closely punctured with 
fuscous, especially the juga; sides nearly parallel, almost truncate in 
front; sometimes tylus a little longer than juga and the inner angles of 
the latter acute. Ocelli red, near posterior margin of head. Rostrum pale 
clay yellow, moderately stout, reaching posterior coxae, the apical segment 
reddish brown. Antennae slender, the basal segment very short, pale 
brown on outer surface; rest of segments rufous, the fourth and fifth 
sometimes tinged with brown. Pronotum with antero-lateral margins 
denticulate and narrowly bordered with yellow; humeral angles produced 
into long slender spines which are often tipped with fuscous or black; 
upper surface of pronotum irregularly punctured, the punctures more 
crowded along the antero-lateral margins and at outer ends of callosities. 
Scutellum similarly colored and punctured except towards apex which is 
less densely punctured and barely surpasses the base of the membrane. A 
more or less well defined, calloused, impunctate line extends from the anter- 
ior margin of the pronotum to tip of scutellum. Coriaceous portion of heme- 
lytra colored like scutellum but more finely and sparsely punctate and 
usually tinged with red in the cuneal and embolial regions; membrane 
translucent, tinged with brownish and with a dusky longitudinal vitta at 
tip. Venter pale yellow, finely, rather sparsely punctate with red and 
brown; a row of small black spots on each margin at the angles of the 
segments; stigmata, a row of small spots on either side within these and a 
large oval spot on the apical segment black; anterior to this large oval 
spot some specimens show as many as three much smaller spots, one on 
each of the segments; some show two, some one, while others have only 
the large apical one; ventral spine long, slender, reaching between hind 
coxae. Connexivum pale orange with large greenish black marks at the 
incisures. Pleurae colored like venter, punctured with brown and with 
some small black spots one of which is always found at the tip of the 
ostiolar canal. Legs pale yellow to orange, finely punctate; femora usually 
with two black spots on under side near tip. Length, 10.0-14.0 mm. 
Width across pronotum, 6.0-8.0 mm.
