biipal band rufous, Avhifli boars sparse reddisli-yellow liairs. Head mod- 

 erately coarsely and densely punctate, pubescence cinereous and dense. 

 Antennae piceous ; thorax very convex anteriorly, anterior two-thirds of 

 lateral margin invisible from above, sides arcuate, basal fovea indistinct ; 

 finely and densely punctate, covered at sides, base and front with cine- 

 reous pubescence, leaving a large triangular spot at middle naked. Scu- 

 tellum black, sparsely pubescent. 



Elytra black, basal third rufous, bearing an irregular transverse band of 

 yellowish hairs ; pubescence black, with a transverse spot on each side of 

 suture, at middle, and some faint mottlings ; cinereous, under surface 

 clothed with dense, white hairs. Lateral spots on abdomen distinct ; last 

 segment white, legs sparsely pubescent, except the basal half of femora 

 which is covered witlj dense white hairs. Length .28 inch ; 7 mm. 



A number of specimens received by Dr. Horn from Texas, on compari- 

 son with the type in Dr. LeConte's cabinet, prove to be of this species. 

 The original description was of an immature form from an uncertain 

 locality. The characters to be relied upon are the convex, naked at 

 middle, thorax, with uniformly cinereous pubescence, faint basal puncture ; 

 the elytral rufous band ; and the femora white at base. 



D. pulcher Lee. Elongate, mod'erately convex, red, covered with 

 sparse, short, recumbent, golden pubescence. Elytra black, except a 

 narrow basal band, which is red. Head finely and moderately densely 

 punctate. Thorax only moderately convex, lateral margins entirely visible 

 from above, gently arcuate, base broadly lobed, two distinct basal foveteon 

 each side of lobe, hind angles prominent ; finely and densel)'- punctate. 

 Elytra densely, moderately coarsely punctate ; a few faint strite indicated 

 near apex, black, covered with very sparse, fine, black pubescence, ex- 

 cept the base which is red, clothed with golden liairs. Scutellum punc- 

 tate. Entire under surface (also antenn?e and legs) red, finely punctate, 

 pubescence fine. Length 25 inch ; 6.2 mm. (Fig. 16.) 



No trouble will be found in distinguishing this species ; the general red 

 color, with the almost entirely black elytra, the flattened thorax, with two 

 basal fovese ; the absence of abdominal spots and white rings on femora, 

 furnish conclusive characters. 



Occurs in the Southern, Middle and Western States. 



D. lardarius Linn. Elongate, moderately convex, black or piceous, 

 clothed with short black sparse recumbent pubescence. El^'tra marked at 

 base with a broad rufous space which is covered with cinereous yellow and 

 three spots of black pubescence. Under surface and legs black with yellow- 

 ish pubescence, without spots or rings. Head moderately coarsely but very 

 densely punctate, antennaj rufous. Thorax moderately convex, lateral 

 margins entirely visible from above, basal fovea not very deep ; finely, 

 but very densely punctate, pubescence black, scutellum covered with 

 black pubescence. Elytra finely, but very densely, punctate, indistinct 

 striic near apex, black with a space at base rufous which bears yellow
