rufous; anterior til)ia' evliiulrical at basal tliinl, then rather suddenly broadened 

 on inner niarfjhi in 'J) . on outer in 9 • ^"'1 continiiin.i; nearly parallel to apex ; 

 apex truncate, exterior angle acute, produced ; femora with a small, sharp tooth, 

 the punctures (6 "^,7 9) being rather large and deep. Length 9.5 — 10 mm.; 

 breadth 5.5-6 mm. 



Hah. — -Texas. Described from two males and two females. 



Resembling closely caroliniis, but quite distinct on account of the 

 sutural angles of the elytra being evidently produced, and the dif- 

 ferences in the male genitalia. 



D. serruIaluK Lee. Pis. 5, 6, figs. 9, 9a and 9i. — Size moderate to small, 

 very convex, strongly narrowed in front; surface polished black with purplish 

 reflection, shining, not bronzed, punctures and strise obliterated ; lateral margins 

 of elytra slightly sinuate at exterior apical angles, apices truucate, sutural angles 

 evident, depressions moderate, apices distinctly serrate ; under surface chestnut- 

 brown, shining; anterior tibite cylindrical at basal third, then rather suddenly 

 broadened on inner margin in %, on outer in 9i ^'id continuing nearly parallel 

 to apex: apex truncate; exterior angle obtuse, rounded : femoi-a with a distinct, 

 acute tooth, punctures (9 %, , 10 9 ) moderately deep and closely placed. Length 

 9 12 mm. ; breadth .5-7 mm. 



Hab. — All the specimens I have seen, about one hundred, are 

 from Florida. 



A very distinct species and readily recognized. While the varia- 

 tion in size is great, it keeps remarkably true to form. 



D. aiialis Eeg. Pis. 5, 6, figs. 10, 10a and 106. — Size moderate, broadly oval, 

 narrowed in front; surface shining, not strongly bronzed, stria; faint; % lateral 

 margins of the elytra slightly sinuate at exterior apical angle, apices feebly sinuate 

 and dehiscent at suture, sutural angles evident ; 9 margins more sinuate, apices 

 more dehiscent at suture and sutural angles somewhat produced : depressions not 

 deep, apices finely serrate : under surface dark brown, last segment and middle 

 and posterior femora rufous, tibise and tarsi testaceous ; anterior tibise cylindrical 

 at basal third, then rather suddenly broadened on inner margin in %, , on outer 

 in 9 . Jiud continuing nearly ])arall el to apex ; apex truncate, exterior apical angle 

 obtuse, rounded ; femoi-a with a moderate tooth, setigerous punctui-es (8 "J, , 9 9 ) 

 dee]) and closely placed. Length 11-11.5 mm. ; breadth 6-6.5 mm. 



Hab.— Texas. 



Dr. Regimbart compares this sjjecies with emargmafus and " aineri- 

 caniis" {assimilis?), but to me it seems more closely related to serru- 

 latus. It is, however, not so sti'ongly convex as that species, the 

 surfiice is bronzed, not polished black, the apices of elytra are sinuate 

 and dehiscent at suture, while this is not the case with serrulatns; 

 the femoral tooth is weaker, the punctures not so numerous, and the 

 serration of the elytra is finer. Dr. Regimbart overlooked this .ser- 

 ration, and, while I have not seen his types, his description leaves no
