 This species is easily distinguished from the preceding by its 

 larger size, paler color, more strongly furrowed elytra and much 

 stronger clypeal notch. However, its separation from some of the 

 other related species is a matter of some difficulty unless the genital 

 armature is examined. 



Serica elusa new species. 



3. Length, 10 mm.; width, 5.5 mm. Color chestnut-brown; upper sur- 

 face bare, polished and shining ; the only trace of a pruinose luster observ- 

 able on the entire body being on the anterior coxae, inferior portion of 

 anterior femora, sixth sternite and margins of pygidium. 



Clypeus but very slightly impressed, with elevated margins, the anterior 

 more strongly so, very slightly reflexed, and moderately sinuate at the middle ; 

 the lateral incisure acute, varying in depth from one-half to the entire 

 width of the elevated margin ; discal area very distinctly tumid at the middle 

 of the lower half; puncturation rather strong, finer and denser on the 

 tumidity, coarser and sparser above it, with the punctures rarely attaining 

 the clypeal suture ; the narrow, irregular, impunctate area thus formed rather 

 emphasizing the already well defined suture. Clypeus and sides of front with 

 a few stiff, erect, golden-brown hairs. Front a little less densely and regu- 

 larly punctured than the upper portion of the clypeus, the punctures con- 

 tiguous to separated by three times their own diameters. Occipital area 

 nearly impunctate. Antennal club rather long, about equalling the total length 

 of the antenna. Eyes moderate in size. Measurements of head as follows : 

 Diameter of head through eyes, 26.5 ; distance between inner eye margins, 

 16; length of head on median line, 18; extreme width of clypeus in front of 

 incisure, 12; antennal club, 10.5. Dorso-ventral diameter of eye, xo. 



Pronotum nearly twice as wide as long, moderately convex, sides but 

 little convergent through the posterior three-fifths of their length, then 

 broadly rounded to the anterior angles ; rather coarsely punctured, more
