“At first sight a little similar to A pudicus Stal. as to size and color, 
but proportionately a little less narrow; less narrowed behind; the small 
brownish spots a little more merked on the head and the pronot™m, 
which is not punctate on the margins, and without devressions or wrinkles 
on the middle of the anterior border of the pronotum. The pronotum 
very little enlarged behind, the leteral margins a'most paratel noste- 
riorly. With almost no transverse fvrrew; very feebly marked on the 
margins. The posterior part behind the furrow paie, quite smooth, but 
covered by a few inconspicuous. very tiny black points. The head very 
notably punctate on each side near the eyes. these much lareer nronor- 
tionately than in A. pudicus Stal, as wide with the eyes as half the width 
of the pronotum. Scutellum and elvtra of a uniformly deep brown 
without spots or clear areas except the embolium, which is yellowish on 
the basal % for its entire width. the apical 14 brownish. Margin of 
elytra is very slightly sinvate behind the embolium. Commissure of the 
clavus a little less than half the length of the scutellum. Connexivum 
yellowish with a slight amber band coverine the tins and the bases of 
the segments. Pecsterior angles of the segments not prominent. Length, 
8 mm.; width, 4.8 mm. Texas.”
