Athysanus plebejus, Kirschb., Athys. Art., 8, 6; Scott, 
Ent. Mo. Mag., xii., 98, 8. 
Pale brownish yellow; elytra sparingly speckled with black 
along the nerves; transverse nerve and the apices of the anal and 
axillary nerves milk-white. Crown in the male as long as half its 
basal width, one-half longer in the middle than at the sides; in 
the female a little shorter than half its basal width, twice as long 
in the middle as at the sides; the free margin in the male sub- 
parallel with the curve of the hind margin, in the female forming 
an obtuse but distinct angle. Pronotum about two-thirds longer 
than the crown. Markings on the crown precisely similar in form 
to those of A. obscwrellus, but in point of intensity only equal to 
the female of that species. Frons pale, with black transverse 
lines, its middle line pale at least below. Elytra as long as or a 
little shorter than the abdomen, widely rounded at the apex; 
nerves whitish. Abdomen above black, margins of the segments 
narrowly yellow, under side black, with a row of yellow spots 
down each side, or yellow, with a wide more or less interrupted 
black stripe down the middle. Legs striped and spotted with 
black; thighs only occasionally with a black band near the apex. 
Length, 4—5i mm. 
Common amongst grasses, especially in damp places. 
Very closely allied to A. obscurellus, but distinguishable 
by its larger size, wider and more obtuse form, paler 
colour, and the milk-white spots on the elytra.

Brownish yellow ; elytra closely and finely speckled with black. 
Crown subequal in length to half its basal width, nearly one-half 
longer in the middle than at the sides, its free sides gently arcuate, 
the angle obtuse; basal markings annular; the interocular line 
thickened and more or less widely interrupted in the middle; 
interocellar line broken up into four spots; infraocellar line 
biarcuate, well-defined. Frons black, the usual lines yellow.
