NORTH AMERICAN GEOTRUPINAE — HOWDEN 285 



and beginning^of margin'^much'^moro^obtuse than'm^^ro/wnc?us (pi, 2, 

 fig. 4a). Much of ventral surface covered with long reddish setae. 

 Median portions of the last three or four abdominal segments shiny, 

 setae generally sparse medially. Tibia with many long spinelike 

 setae lining outer edges and carinae. In the holotype the apical tooth 

 of the outer margin of the foretibia is greatly modified, elongate, bent 

 rectangularly inwards, slightly recurved with inner edge sinuate. In 

 addition, the foretibia has a row of four elongate conical teeth on inner 

 surface. The hind femur is also modified by having a small tubercle 

 present near the posterior .^margin of the coxa. 



Genitalia and genital capsule large and heavily sclerotized. Capsule 

 with dorsal and ventral plates)^ fringed with a few^ short setae. Geni- 

 talia quite complex, with two dorsal parameres and a bilobed ventral 

 phallobase (pi. 3, fig. 7). The short complex right dorsal paramere 

 with the posterior edge of bulbular basal portion usually forming a 

 wide kregular V, slightly less oblique than in profundus (pi. 2, fig. 5a). 



Allotype: Female. Length 19 mm., greatest width 13 mm. 



Color of dorsum black with bluish green iridescence lacking except 

 along elytral margins, where it is most pronounced near the elytral 

 apices. The allotype differs from the holotype in several other 

 respects. In the allotype the punctures of the clypeus are pronounced 

 and numerous, the fine secondary punctures of the pronotum are 

 almost absent, the elytral striae are obsolete, and the rows of elytral 

 punctures are slightly less pronounced than in the holotype. The 

 hind femur of the allotype lacks the tubercle present in the male, and 

 the foretibia has the unmodified apical tooth similar in shape to the 

 penultimate tooth. Tarsal claws are identical in size and shape to 

 those of the holotype, as are other major characteristics.
