A NEW SPECIES OF DINEUTES. 



By Charles W. Leng, 

 West New Brighton, New York, 



Dineutes robertsi, new species. 



Very large, entirely bronzed above, testaceous beneath. Regularly oval, 

 feebly convex ; upper surface entirely bronzed, very shining, very minutely 

 punctulate, with larger shallow punctures intermingled, which become more 

 abundant towards apex of elytra ; striae of elytra very faint even at sides ; lat- 

 eral margins of elytra not sinuate, depressions feeble, sutural angles broadly 

 rounded in both sexes ; under surface, including legs, entirely pale testaceous ; 

 anterior tibiae sinuate, apex truncate ; femur without tooth, its upper surface 

 with punctures (six J, eight J'), from which proceed stout hairs. A row of 

 ■stouter hairs proceed also from groove of femur. Length, 13 to 16 mm. 



West Branch War Woman Creek, Rabun Co., Ga., in the moun- 

 tains, at an elevation of about 2,000 feet. 



This species closely resembles vittatus in form and structure, but 

 is a little larger and therefore the largest species we have. It differs 

 •especially in color, being entirely bronzed above instead of vittate 

 as in vittatus, and entirely pale testaceous beneath instead of dark 

 brown with middle and posterior tibiae pale as in vittatus. The punc- 

 tuation is also different and the elytral striae are not more evident 

 at sides. 



This species was first observed by Mr. Davis and myself in June, 

 1909, at a ford where the road from Clayton, Ga., to Bleckley's Store 

 •crosses the west branch of War Woman Creek. A few specimens 

 were taken at that time, and in July, 1910, Mr. Davis obtained a 

 good series by wading some distance up the stream in which unfor- 

 tunately no very large schools were seen. Later what appeared to 

 be the same species was seen in Tuckaluge Creek, near by, but none 

 was captured. It is, however, probable that this species occurs else- 

 where in the mountains. 



I take great pleasure in dedicating this fine species to the friend 

 of many years, Mr. Chris. H. Roberts, whose paper, " On the Species 

 of Dineutes," has made their determination possible and certain.
