Cyrtomenus (Cyrtomenus) crassus Walker

Diagnosis. The very broadly rounded anteocular part of head beyond which the eyes project only slightly, added to the presence of a postmedian row of setigerous punctures on lateral third of sternites IV to VI, will separate this species. Body length 7.93 to 8.98 mm.

Head. Anterior margin very broadly rounded; eyes projecting beyond sides of head by not more than onethird their width; juga longer than tylus and nearly or quite contiguous in front of it; apices of juga and tylus broadly recurved; surface noticeably convex, shining, with prominent, coarse, irregular rugae radiating from base of tylus, minutely punctuate; jugum ventrally shining, in part obsoletely rugulose. Pronotum. Lateral margin straight to slightly concave on basal two-thirds, with submarginal row of 15 to 18 setigerous punctures; transverse impression distinct laterally, obsolete medially, interrupted medially by a irregular row of coarse punctures; anterior lobe impunctate except for moderate punctures laterally and in subapical band; posterior lobe with several coarse punctures anteriorly, these more numerous medially; propleuron shining, with few distinct punctures in depression; mesopleuron with lateral area polished, impunctate, with few oblique rugulae; metapleuron with lateral margin of evaporatorium more or less concave, lateral area polished and impunctate. Scutellum. Length subequal to, slightly longer or shorter than width; disc with few to several widely scattered, coarse, sunken punctures. Hemelytra. Clavus and corium shining; clavus with one submedian row of punctures; mesocorial punctuation forming two rows, elsewhere, except along radial vein, uniformly punctuate; exocorium more irregularly and less densely punctuate than mesocorium; costa with six to ten setigerous punctures. Legs. Posterior tibia strongly dilated toward apex; anterior tibia with nine or ten stout, flattened, blunt spines arising from blackened elevation on dorsal margin. Sternites shining, polished or faintly alutaceous, rugulose in spiracular area; setigerous punctures on segments III to VII prominent, with long setae.
