In this description and those following, where width is given with length, 

 length is always given first. Head 0.34 x 0.36 mm. through eyes; pronotum 

 0.36 X 0.48 mm.; elytra 0.56 along suture x 0.71 to 0.73; abdomen 0.69 x 0.72 

 to 0.74 mm.; tergite I, 0.268; tergite II + III, 0.281. Total length 1.95 to 1.97 

 mm.; greatest width 0.72 to 0.75 mm. (PI. XV.) 



General body color light red brown, with the antennae, palpi, and tarsi 

 paler; pubescence yellowish white, sparse, long, conspicuous. Average length 

 of body pubescence 0.067 to 0.107 mm. Integument shining, with setae arising 

 from subasperate punctures. 



Head rounded-triangular, broadest through eyes, tapering gradually to 

 the broadly rounded front. Eyes large, composed of about 40 coarse facets. 

 Eyes slightly hairy. Occiput sinuate posteriorly, with a median notch; vertex 

 evenly rounded, vertexal foveae large. Intra-foveal distance about equal to 

 distance between an eye and nearest fovea. These vertexal foveae located 

 in the center of the vertex, equidistant from the posterior margin of the oc- 

 ciput and from the anterior margin of the antennal insertions. A broad, well 

 defined sulcus from each fovea to a point above each antennal insertion ; mar- 

 gins of the sulcus rounded ; sulcus broadest near fovea, not deepening anteriorly, 

 forming as a whole an elongate-oval impression; foveae nude. Front simple, 

 unmodified, evenly declivous. Antennae inserted on front without formation 

 of antennal tubercle, distant at their bases; eleven-segmented. Segment I 

 and II equal in length and width; I regularly ovate; II truncate apically; 

 III, IV, V, VI of about same width; III a little longer than IV, ovate; IV and 

 V moniliform, about same length; V as long as VI; VI subtriangular, asym- 

 metrically slightly produced at anterior basal face; VII about as long as VI, 

 slightly wider, subtriangular, produced more strongly at anterior basal face; 

 VIII, IX, X and XI forming the club; VIII, IX and X of same shape — 

 that is, the basal half of each segment is drum-shaped and the apical half 

 consists of a slender, slightly eccentric, tapering, narrower spindle; VIII 

 slightly shorter and narrower than IX; IX slightly narrower than X; IX and 

 X of about same length; XI truncate at base, widest through middle third, 

 tapering to subacute apex, slightly wider than X, twice as long as X. Maxillary 

 palpi four-segmented; first segment very minute; second segment elongate, 

 slender basally, gradually inflated apically; third segment much shorter than 

 second, but elongate, roughly elongate-rounded triangular in outline with 

 the inner face much more convex than outer face; fourth segment longest.
