Serica aspera new species. 



Like the preceding species aspera bears a remarkable resemblance to 

 parallela. It averages slightly smaller, and the antennal clubs are distinctly 

 longer, measuring 12 instead of 10 as in parallela. By the characters shown 

 in the male genital armature (PI. XV) the species can be readily separated 

 from mystaca and parallela, but without the aid of these characters its 

 certain identification must be considered open to question.

Serica delicata new species. 



(^. Length. 7.5 mm. ; width, 4 mm. Color amber brown, surface opaque 

 and only slightly iridescent. 



Clypeus broadly and very feebly convex in the apical two thirds, apical 

 and lateral margins suddenly, moderately elevated, clypeal notch obsolete, 

 but its position indicated by a slight angulation of the elevated rim at 

 the point of juncture of its apical and lateral parts, apical margin viewed 

 perpendicularly, evenly and moderately curved or bent, viewed at an angle 

 from above, feebly arcuate ; surface of clypeus evenly and closely covered 

 with small punctures, separated by a little less than their own diameters. 

 Front a little less closely punctured. Eyes and antennal clubs relatively 

 large. Measurements of head : diameter through eyes, 22 ; distance between 

 inner eye margins, 11; length of head on median line, 15; extreme width 

 of anterior reflexed margin, 9; antennal club, 12; dorso-ventral diameter 

 of eye, 9. 



Pronotum only feebly convex, sides nearly straight and but slightly con- 

 vergent anteriorly, and showing, as is usual with the pallid species, a small, 

 mid-lateral, piceous spot; punctures small, evenly and closely placed, separated 

 on the average by about their own diameters. Measurements of pronotum : 

 width through posterior angles. 32 ; width through anterior angles, 23 ; length 

 on median line, 19. 



Elytra with distinct line-like striae, each stria with a regular row of small.
