Dec, 1922.] Dawson : New Species of Serica. 155 



in the anterior third, with a distinct margin and 8 or 9 erect, brown setae ; 

 anterior margin of pronotum less distinct than the lateral margins and with 

 smaller setae which become obsolete toward the center ; surface of pronotum 

 finely and rather evenly punctured, the pu^ictures shining and separated by 

 one to three times their own diameters. 



Measurements of pronotum : width through posterior angles, 40 ; width 

 through anterior angles, 24 ; length on median line, 20. 



Elytra with moderately impressed, usually line-like sulci, each with one 

 to three confused rows of small shining punctures ; interspaces of elytra 

 evenly and moderately convex, sparsely and irregularly punctured, length 

 70, width 52. 



Metasternum and posterior coxal plates nearly bare, with relatively fine 

 punctures separated by about one to two diameters. Hind femora rather 

 finely and sparsely punctured, but with two regular and nearly parallel rows 

 of rather strong, setigerous punctures with about eight setae to the row. 

 Abdominal sternites finely and rather closely punctured and with well-de- 

 veloped rows of ambulatorial setae. Pygidium similarly punctured, usually 

 showing a slightly elevated, median, longitudinal line. 



The genital armature of the male (PI. XI) practically symmetrical; length 

 2.5 mm. 



$. Differs from the male in having the head, and pronotum rather 

 more coarsely punctured, shining, not opaque and velvety, and usually with- 

 out any iridescent luster. The antennal clubs are distinctly smaller than 

 in the male, measuring 8 instead of 11.5. 



The description and drawings are based upon a male and female labeled 

 "Bergen county, N. J.. May 19, 1918, Under leaves (E. D. Quirsfeld)." 

 On the assumption that Illiger's type (1802) is probably no longer in exist- 

 ence, these specimens are being labeled as neotypes.
