fringe of black pubescence; first tergite laterally distinctly dentate 

 just anterior to the median line; second tergite with elongate, con- 

 tiguous punctures, the punctures larger laterally, the disk clothed 

 with sparse, recumbent, ferruginous pubescence, at the base medially 

 a few black hairs, laterally with sparse, black pubescence, and the 

 apical margin with a thick fringe of black pubescence; tergites 3-5 

 with moderate, shallow contiguous punctures throughout, sparsely 

 clothed with long, black pubescence; pygidial area, coarsely, longi- 

 tudinally striate, the striae not extending to the apical margin ; first 

 sternite produced anteriorly into a prominent tooth, VN'ith large con- 

 tiguous punctures, and sparsely clothed with long, black, erect pubes- 

 cence ; second sternite with distinct separated punctures, the punctures 

 larger laterally and caudally, very sparsely clothed with long, dark 

 ferruginous pubescence and with an apical fringe of blackish pubes- 

 cence ; sternites 3-5 with large, contiguous punctures throughout and 

 each with an apical fringe of black pubsecence ; ultimate sternite con- 

 fluently punctate and sparsely clothed with black pubsecence. 



Leg black, sparsely clothed with dark ferruginous pubescence. 



Holotype.— Male, Cat. No. 40725, U.S.N.M., Eosser, Tex., June 28, 

 1905 (C. K. Jones).

Paratypes.— Female, Colorado County, Tex., August 25, 1922 

 (Grace O. Wiley) ; female, Columbus, Tex. (Wickham) ; 5 males, 

 5 females, Rosser, Tex., June 28, 1905 (C. R. Jones) ; female, Rosser, 

 Tex., July 6, 1905 (C. R. Jones) ; female, Rosser, Tex., July 6, 1905 

 (F. C. Bishopp) ; female, Rosser, Tex., July 7, 1905 (C. R. Jones) ; 

 female, Rosser, Tex., September 23, 1905 (C. R. Jones) ; female, 

 Calvert, Tex., August 23, 1907 (R. A. Cushman) ; 2 females, Mineola, 

 Tex., July 19, 1906 (Bishopp and Jones) ; in collections of United 

 States National Museum, the University of Minnesota, and the 

 author. 



The large size of both the male and female, and the section of 

 the genus to which they belong, leads me to place these specimens 

 as male and female of the same species. The genitalia of the male 

 are like those of lepeletierii and are therefore not figured. The 

 antennal scrobes carinate above, the broad, glabrous and impunctate 

 base of the lateral lobes of the anterior division of the scutellum, 

 the carina defining the cephalic margin of the propleura not reach- 

 ing the humeral tubercle, the coarser puncturation of abdominal 

 tergites 3-6, and its large size distinguish the male from the male of 

 lepeletieHi. The male paratypes vary in length from 14 to 20 mm.
