Redescription. Male: Length, 26–36 mm. Form large, broad, parallel sided; integument orange or yellow-orange, the lower part of head, antennae, sterna at sides, femora at apex, base, and trochanters, tibiae and tarsi black, pronotum spotted with black, elytra black with 2 transverse orange bands, connected along lateral margin, posterior band not reaching suture. Head with vertex coarsely, confluently punctate; palpi short, apical segment of labial and maxillary pair truncate at apices, impressed dorsally; antennal tubercles broad, slightly elevated, apices obtusely angulate; antennae exceeding elytral apices by about 3 segments, scape with apical 2/3 of dorsum impressed, dorsal surface of 3rd impressed (longitudinally canaliculate) at apical 2/3, 3rd segment longer than 1st, 4th shorter than 3rd, 5th longer than 4th, each segment from 6th–10th longer than 5th, 11th much longer than 10th, scarcely appendiculate. Pronotum dull, broader than long (1.7 x as broad as long), sides with prominent, recurved lateral spines, base shallowly impressed, surface coarsely, contiguously punctate, very sparsely obscurely pubescent, disc with an elevated black tubercle at middle and pair of black, obliquely connected tubercles on each side; prosternum shallowly and less coarsely punctate than pronotum, sides and around coxae densely clothed with golden suberect hair, prosternal process large, prominent, wide and arcuate; mesosternum with intercoxal process flat, not obviously projected below base of coxae, sides densely clothed with golden, erect pubescence; metasternum shining, densely pubescent with erect, golden hair, metepisternum broad, black. Scutellum triangular, as long as wide, yellow-orange, and acutely pointed apically. Elytra about 2.2 times longer than broad, sides slightly tapering, distinctly margined laterally; surface very coarsely, deeply, confluently punctate in front of basal band, densely but a little less coarsely punctate behind; apices broadly rounded to suture, sutural angle rounded. Legs with hind femora elongate but not attaining elytral apices. Abdomen shining, finely, densely pubescent, and densely punctate; 5th sternite subangularly emarginate at apex.

Female: Length, 25–38 mm. Form large, broad, slightly explanate posteriorly. Antennae reaching to apical ¼ of elytra, outer segments compressed, dorsal surface of 3rd without longitudinal impression found in male, 3rd segment subequal to 1st, 4th shorter than 1st, each segment from 5th–7th subequal to 1st, 8th–10th gradually shorter than 7th, 11th longer than 10th and subequal to 4th, appendiculate; pronotum with structures similar to male; prosternum as in male, except intercoxal process longitudinally depressed in middle. Elytra 2.2 times longer than broad (humerus width vs. length). Abdomen with 5th sternite broadly and shallowly emarginate at apex.

Distribution. United States (Arizona), northern Mexico (Chihuahua).

Materials examined. USA: Arizona: Cochise Co., Dragoon Mtns, Texas Pass, 14 July 1980, Cicero (4 males, 1 female); 14-15 July 1980, Cicero (4 females); 15 July 1980, F.T. Hovore (1 male); Texas Pass, 19 July 1917, J.C. Bradley (1 male); I-10, Texas Canyon, 20 July 1980, oak, 17 July 1983, P. Meyer (3 males); Texas Canyon, 16 July 1977, E. Giesbert (5 males, 5 females), 17 July 1977, E. Giesbert (7 males, 7 females); Miller Canyon, 18 July 1973 (1 male). Materials examined were from: BKEC, CASC, EMEC, and FSCA.

Note. Megapurpuricenus magnificus can easily be distinguished from other large and robust non-metallic genera by the color and texture of the integument, which is coarsely, confluently punctate. Unlike Crioprosopus Audinet-Serville the vertex is also coarsely, confluently punctate. The lateral spines on the pronotum are acute and recurved. The disc of the pronotum has elevated black tubercles at the middle, and a pair of black obliquely connected tubercles on each side. The elytra are without long erect hairs as in Pilostenaspis gen. nov. or obscurely clothed with very short hairs as in some species of Purpuricenus Dejean. Femora and tibia are finely punctate, and are not covered with long erect hairs as in Pilostenaspis . The prosternal intercoxal process is large, wide and prominent, especially in males.
