March, 1919! DaWSOX : New SPECIES OF SERICA. 35 



strong, uniform and rather dense, the punctures separated by one half to two 

 thirds of their own diameters. Front much less densely punctured ; the punc- 

 tures irregularly placed, contiguous to separated by three or four times their 

 own diameters. Occipital area nearly impunctate. Antennal club rather long, 

 about equal to the total length of the antenna. The eyes are relatively large, 

 and the head narrow anteriorly, as is shown by the following measurements : 

 Diameter of head through eyes, 28; distance between inner eye margins, 16; 

 length of head on median line, 20.5 ; extreme width of clypeus in front of 

 incisure, 13; antennal club, 11.3; dorso-ventral diameter of eye, 11. 



Pronotum transverse and only moderately convex ; sides but little con- 

 vergent through the posterior two thirds of their length, then rather suddenly 

 rounded inwardly to the anterior angles; puncturation similar to that of the 

 front, becoming somewhat closer toward the sides. The pronotal measure- 

 ments are as follows: Width through the posterior angles, 44; width through 

 the anterior angles, 29; length on median line, 24.5. Scutellum closely punc- 

 tured at the sides, nearly impunctate through the center and at the apex; 

 though apparently longer than wide, the actual measurements are: Base, 11; 

 length, 12. 



Elytra strongly furrowed, the sulci densely and coarsely punctured, with 

 the punctures arranged in three irregular rows which show a tendency to 

 become laterally confluent. Elytral costae well rounded and with a few large 

 scattered punctures. Length of elytra, 81 ; greatest width, 55—60. Body be- 

 neath coarsely, not closely punctured, the punctures finer on the abdomen. 

 Fourth sternite often more or less impressed at the middle, sometimes show- 

 ing a fine, longitudinal line through the vaguely defined impression. The 

 single, submarginal rows of setae seen on the sternites of most of the species 

 are here nearly or quite wanting, although rows of slightly coarser punctures 

 are traceable. Metasternum similar to that of the preceding species. 



The genital armature of this species is unusually large, measuring 3.4 mm. 

 in length. Its general characteristics are sufficiently indicated by the figures 

 on Plate VII, but attention should be drawn to the nature and extent of the 

 variations observed. The sides of the stalk are often much less convergent 

 toward the tip than is shown in the figure, in a few examples nearly parallel, 

 also the recurved rims of the claspers are often much less angulate, in fact 

 the angulation nearly or quite disappears in a few specimens. A single speci- 

 men is at hand from Clayton, Georgia, with the stalk much shortened. 



$?. Differs from the male only in the usual secondary characters men- 

 tioned in the preceding description.
