Sept.-Dec, igji.] D.wvsox : Xew Stecies OF Serica. 107 



Clypcus with the discal area jiractically continuous with the slight, even 

 convexity of the front, its margins rather strongly elevated, scarcely less so 

 at the sides which are not separated from the apical portion by an incisure, 

 there being a scarcely discernible waver in the elevated margin at the juncture 

 of its apical and lateral parts ; viewed perpendicularly the anterior margin is 

 straight, viewed at an angle from above a slight median prominence is evident; 

 surface of clypeus finely, evenly, and closely punctured, the punctures sep- 

 arated by about half their own diameters. Clypeal suture very fine and indis- 

 tinct. Front a little less strongly, closely and evenly punctured than the 

 clypeus. Antennal club of moderate size about equal to the total length of the 

 antenna beyond the basal constriction of the first segment. Eyes relatively 

 small. Measurements of head in tenths of a milliiiKter: diameter of head 

 through eyes, 19; distance between inner eye margins, 13; length of head on 

 median line, 15: antennal club. 7.5; dorso-ventral diameter of eye, 6. 



Pronotum moderately and evenly convex, the surface finely, closely and 

 evenly punctured, the punctures separated by about their own diameters, 

 slightly more at the middle and less at the sides; posterior angles rather obtuse 

 and rounded, anterior angles distinct ; width of pronotum, viewed vertically, 

 carried forward to the middle, then distinctly decreasing to the anterior angles; 

 lateral margins, viewed from the side, rather strongly and evenly arcuate from 

 base to apex ; near the lateral margins and about three fifths of the way from 

 the base a small, slightly impressed area with a sniill, pigmented spot on its 

 posterior margin. Measurements of pronotum as follows: width through poste- 

 rior angles. 30 ; width through anterior angles, 20 ; length on median line, 18. 

 Scutellum finely and densely punctured except for a small median and basal 

 area ; l^-ngth. 7 ; width, S. 



Elytra with rather feebly impressed, line-like striae, each stria with a single 

 row of small punctures, separated by a little more than their own diameters, 

 the rows of punctures, however, somewhat confused or obscured by admixture 

 with the sparse, scattered punctures of the intervals. The intervals feebly 

 convex, the second, fourth, sixth and eighth very slightly wider than the others. 

 Length of elytra, 53 ; width. 37. 



Metasternum and posterior coxal plates, especially the latter, shining and 

 polished, elsewhere, except the femora, tibia; and tarsi, with the surface dulled 

 by a sericeous bloom. Beneath, except on the abdomen, thinly clothed with 

 erect, yellow hairs, the hairs on the metasternum comparatively short, about 

 half the length of those on the anterior and middle coxae and femora. Punc- 

 turation fine and close on the metasternum, distinctly stronger and a little less 

 dense on the posterior coxal plates, and very fine or minute on the abdomen, 

 where the punctures bear short, inconspicuous, recumbent hairs. The usual, 

 single rows of coarse setigerous punctures well developed on the abdominal 

 sternitcs. 



Length of genital annature of male, 2.7 mm. (PI. XI\). .\ttintion should 

 be drawn to an important structural feature not clearly shown in the figures.
