The white scales on the median portion of tlu> dorsum of the pronotum are restricted to a prom- inent basal patch (Fig. 2) instead of fonning a median vitta the length of the pronotum. In most specimens the rostrum is slightly expanded in the extreme distal portion, scales on the ros- trum are elongate-oval and pointed ratlier than parallel sided, scales on tlu- pronotum are nar- row and dark in color. o\al scales on the femur are white, and the long, narrow scales are dark in color. Description. Male: ieiigtli '15 mm; in- tegument black to piceous appendages iiglit to dark reddish brown. \'estiturc of white to dark reddish brown scales. Rostrum slightJN' shorter or al)out same length as prodiorax, length 20 to 2S percent of total body length, antennal insertion on apical fourth; evenlv, prominenth' arcuate from base to apex in dorsal pioiile. In dorsal aspect prominently, esenlv tapered from base to apex, frons times wider between dorsal margin of eyes than rostrum at extreme apex; distad of antennal in- sertion oblong in cross section, not finely acu- minate; smooth, shining, lateral pits shallow; often slightly expanded at antennal insertion and at extrem(> apex. Vestiture of elongate-oyal, apically pointed, white, recumbent scales, and long, narrow, strigose, suberect scales; no fine erect setae, some round, nonstrigose scales on lower portion of sides. .\ntennal funicle seven-segmented; pedicel as long or longer than next three segments com- bined. Pronotum wider than long, base about times wider than apex at apical constiiction; sides evenly, prominently rounded; punctures large, evenly spaced, broadly visible on disc. Vestiture comp
