The material studied seems to indicate a definite correlation be- 

 tween the intensity of certain characters and the geographical dis- 

 tribution of the species. Northern specimens average larger, some- 

 limes reaching ten millimeters in length, while southern specimens 

 are smaller, usually measuring less than nine millimeters, and some- 

 times down to seven. Southern specimens also seem to average 

 lighter in color, frequently being pale chestnut or testaceous. Accom- 

 panying the reduction in size and color intensity occurs some modi- 

 fication of the male genital armature. The characteristic sudden and 

 strong inflation of the stalk of the armature seems to become pro- 

 gressively less well marked, until in the Alabama specimens the stalk 

 is but little modified. The specimens from Southern Pines, North 

 Carolina and Gainesville, Georgia, show a moderate ainount of ex- 

 pansion or widening of the terminal portion of the claspers. 



Among the previously described species lecontei is most closely re- 

 lated to georgiana Leng, but the latter species may be recognized at 

 once by its very str.ongly tumid clypeus. The genital armatures of 

 the two species are very similar, but the stalk of the armature in 

 georgiana is never so strongly and suddenly enlarged as in typical 

 Iccontei. 



Serica spicula new species. 



(^. Length 7.5 mm., width 4.5 mm. Color claret brown to chestnut, sur- 

 face bare, polished and shining. 



Clypeus not, or but very slightly, depressed, the discal area below the 

 center with a distinct median tumidity, nearly as prominent, when viewed from 

 the side, as the reflexed anterior margin. Anterior margin abruptly, mod- 

 erately elevated, divided from the less strongly and suddenly elevated lateral 

 margins by deep and acute incisures. Viewed perpendicularly the anterior, 

 reflexed margin broadly and feebly emarginate medially, viewed at an angle 

 from above, evenly but very slightly arcuate. Clypeal suture nearly arcuate,
