PRELIMINARY LIST 
narrow, prominent, black; rostrum slender, testaf^eous, piceous at tip, reaching to the 
posterior coxae; antennae dull black, of medium length, the second joint nearly as long 
as the line from the tip of scutellum to the apex of clavus, the third joint a little shorter 
and slightly more slender, tapering, the fourth scarcely more than one-third the length 
of the third, still more slender. Pronotum transverse, polished, minutely pubescent, with 
a few sparse punctures on a line in front of the low callosities, lateral margins short, 
oblique, with the edge a little turned down, the collum confined to the middle of the 
margin, and fading into the raised surface before reaching the line of the eyes; humeral 
angles prominent, almost acutely callous; the posterior margin almost straight. Scutel¬ 
lum short, almost flat, clothed with pale pubescence, the base usually exposed, sometimes 
dis'slosing the yellowish spot at each basal angle. Legs dull yellow, the posterior pair 
having the femora black, all the tibiae with black spines and dots at base of spines; tarsi 
piceous at tip. Hemelytra covered with short yellowish pubesence, the clavus wide 
smoky fuscous; corium with a large fuscous, wedge-shaped spot, closed on the middle,^ 
the outer and inner borders and base and tip dull testaceous; the cuneus dusky, bordered 
all around with dull testaceous; membrane dusky, with the veins, base and sometimes 
the outer border pale. Abdomen black, polished, with a large greenish spot near the base, 
and some greenish spots on the pleura. 
Length to end of abdomen 2.25-2.5 mm. Width of pronotum 1-1.26 mm. This species 
inhabits both Colorado and Kansas, It is no doubt quite common, but hitherto only a few 
less mature specimens have been sent to me for examination. It closely resembles A. 
apicalis Uhler, of the Atlantic States, but is a more robust and clumsy style of insect.”
