SCARAB BEETLES CARTWRIGHT 523 



the annular punctures of the oblique geminate striae mostly sejjarated 

 by their diameter or less, those of the intervals about as close at the 

 sides but less so on the disc, coarse punctures finer and closer pos- 

 teriorly. Pygidium quite close!}', finely to veiy moderately punctate 

 throughout, the punctures separated generally b}' one to three times 

 their diameters, sometimes less closely at apex, laterally finer and 

 closer in tlie corners, at times almost scabriculate. Undersurface 

 quite hairy, the strong prosternal process behind the front coxae com- 

 pletely so. Anterior tibia closely, finely, confusedly punctate just 

 outside the longitudinal row of coarse setigerous punctures. Apex of 

 hind tibia moderately flaring, its width less than half the length of tlie 

 tibia measured along the inner edge. First segment of the posterior 

 tarsus usually very little produced laterally, its apical width less than 

 the length of the second segment. Aedeagus as in figure 56. 



Type: Probably lost. Through the kindness of Dr. Rene Malaise, 

 the specimen puiported to be the type of Scarabaevs gibbosus in the 

 DeGeer collection in the Riksmuseum, Stockiiolm, was loaned to me 

 for study. To my surprise I found it to be a specimen of Cyclocephala. 

 This specimen could not possibly have been the type of Scarabaeus 

 gibbosus DeGeer since it does not agree with the original description 

 or the plate showing a rather poor drawing of the species. It does 

 not liave the anterior pronotal depression or pit mentioned in the 

 original description and clearly indicated in the drawing. Further, 

 it does not agree in size, color, or morphological characters as given 

 in the original description. Dr. Malaise states there is no other 

 specimen remaining in the DeGeer collection which could liave been 

 the type. The type of Scarabaeus gibbosus DeGeer must therefore 

 be considered lost or destroyed. 



Type locality: Pennsylvania. 



Specimens examined: 2,700. 



Distribution: Typical gibbosus probably occurs in all States east 

 of the Rocky Mountains except Florida and possibly Vermont, New 

 Hampshire, and Maine. See map, figure 1.
