Oblong, slightly rounded at the sides; female much narrowed 
behind ; elytra slightly (#) or one-third or more (2?) shorter than 
the abdomen; nerves whitish. Crown a little longer than half its 
basal width, twice as long in the middle as at the sides, a trifle 
shorter than the pronotum, its free sides nearly straight, the angle 
pointed; interocular line generally widely interrupted in the 
middle,; interocellar line feeble; infraocellar line biarcuate. A 
very variable species in point of colour. The normal form is pale 
yellowish grey, with the lines on the head and some markings on 
the pronotum and scutellum black, and the areas of the elytra 
more or less filled up with fuscous. The dark form of the male 
has the elytra black with pale nerves, but a very pale immaculate 
form of both sexes is perhaps the most frequent. Of the dark 
markings on the elytra, a spot next the transverse nerve is the last 
to disappear. Hind margin of the last ventral segment in the 
female subangularly concave, with a strong black triangular tooth 
in the middle. Length, 33—4} mm. 
Common and generally distributed. The macropterous 
form, which is rare, has the elytra a little longer than 
the abdomen, and slightly overlapping at the apex.
