longer than wide. Thorax as long as wide, sides gradually narrowed and 

 nearly straight before the middle, subparallel and distinctly sinuate posteriorly, 

 posterior angles distinctly divaricate and unicarinate. Elytra not wider than 

 the thorax, about three times the length, sides subparallel, becoming gradually 

 attenuate behind the middle, striae deep, distinctly punctate, intervals rather 

 feebly convex, rather finely, sparsely and asperately punctured. Length 9.25 

 mm., width 2.5 mm. 

 Type 26 May. 



This species is related to E. nigriiiiis Hrbst. Aside from the 

 color differences it may be distinguished by the thorax gradually 

 narrowed before the middle and distinctly sinuate posteriorly and by 

 the longer elytra. 



NEW SPECIES OF SERICA (SCARAB^ID^). IV. 



By R. W. Dawson, 



Lincoln, Nebraska. 

 Serica lecontei new species. 



(^. Length 9.5 mm., width 5 mm. Color varying from pale to very dark 

 chestnut, surface polished and shining. 



Clypeus nearly level with the plane of the front, sometimes slightly de- 

 pressed, especially toward the sides ; lower median portion feebly tumid ; ante- 

 rior margin moderately but -suddenly reflexed, lateral margins less strongly and 

 suddenly elevated ; lateral incisure narrow and acute extending about two 

 thirds of the depth of the elevated margin. Clypeus rather strongly and closely 

 punctured, the punctures larger and separated by about their own diameters 

 near the suture, smaller and more closely placed on the slightly tumid area 

 just below the middle. Clypeal suture fine but distinct and unmodified. Front 

 less closely and regularly punctured than the clypeus. Antennal club rather 

 large, about equalling the total length of the antenna. Eyes of usvial size. 

 Measurements of head (in tenths of a millimeter) as follows : diameter of head 

 through eyes, 25 ; distance between inner eye margins, 14 ; length of head on 

 median line, 13; extreme width of clypeus in front of the incisure, 12; anten- 

 nal club, 10.5 ; dorso-ventral diameter of eye, 9.4. 



Pronotum moderately convex, the sides but little rounded, gradually con- 

 vergent from the posterior angles to the anterior third, then more strongly 

 rounded to the anterior angles ; posterior angles obtuse but prominent and well 

 marked, sides distinctly margined ; puncturation rather strong and evenly dis- 

 tributed, the punctures separated by one to two times their own diameters. 

 Measurements of pronotum as follows: width through posterior angles, 41;
