TWO NEW SPECIES OF NORTH AMERICAN BRACHYS(GOLEOPTERA: BUPRESTIDAE)JOSEF N. KNULLDepartment of Zoology and Entomology, The Ohio State University, Columbus 10In working over genus Brachys the two following new species have been found.Type material in collection of author.Brachys querci n. sp.Figures 1, 2Male.—Form, size, color and markings similar to B. barberi Fisher (1924). Dorsal surfacecupreous, elytra more brilliant than head and pronotum; ventral surface dark bronze; threerather irregular transverse bands of recumbent white pubescence on elytra.Head convex, with deep median depression extending down front; clypeus deeply emarginate;surface irregularly minutely punctate, white recumbent pubescence scattered, more dense nearepistoma.FIGURE 1. Dorsal view of o" genitalia of Brachys querci n. sp.FIGURE 2. Ventral view of number 1.Pronotum wider than long, widest at base, constricted at apex; anterior margin nearlytruncate; basal margin sinuate, median lobe slightly emarginate in front of scutellum; diskconvex, with basal transverse depression which continues down each side, prehumerai carinaobtuse; surface with round glabrous area each side of median line in middle, punctures irregular,minute, recumbent white pubescence scattered. Scutellum triangular, wider than long, glabrous.THE OHIO JOURNAL OF SCIENCE 52(6): 358, November, 1952.No. 6 NEW SPECIES OF BRACHYS 359Elytra wider than base of pronotum, sides strongly constricted back of base, expanded backof middle, then convergent to rounded, minutely serrulate apices; disk convex, with deep basaldepression each side at middle of each elytron, umbone prominent, lateral carina extending frombase to near apex; surface rather coarsely punctate near base, punctures of rest of area minute,scattered, each bearing a short white hair, forming three rather irregular transverse bands, areasbetween bands smooth.Abdomen sparsely, finely punctate and pubescent; apex of last ventral abdominal segmentbroadly rounded, minutely serrate, suture rounded.Length 3.6 mm; width 1.7 mm.Female.—Similar to male, last abdominal segment truncate; apical margin strongly dentate,suture truncate.Variation.—Sizes vary from 3.3 to 3.6 mm in length and 1.5 to 2.1 mm in width.Holotype o71 and allotype taken from oak foliage in the Davis Mountains, Texas, May 9,1941. Paratypes in same locality May 9 to July 17 and in the Chisos Mountains, Texas, July 17,1946. All material collected by D. J. & J. N. Knull.This species should stand next to B. barberi Fisher, which it resembles very closely. It wascollected with barberi in both localities at the same time. The basal transverse depression onquerci will separate it from the above species. The last ventral abdominal segment is morebroadly rounded in the males of barberi and the genitalia are quite different as figured by Cazier(1951). The last ventral segment of 9 barberi is more broadly rounded and the suture is sinuate.The o71 genitalia will separate it from B. marialicae Caz.Brachys apachei n. sp.Female.—Size and form of B. cephalicus Schaeffer (1909), longer than broad, cuneate poste-riorly, dorsal surface cupreous, with two bluish spots on each elytron; beneath dark bronze; headand pronotum with white and golden recumbent pubescence; elytra with three irregular transversebands of white and golden pubescence.Head convex, with deep median depression extending down front, a transverse depressionabout middle of front; clypeal emargination deep; surface irregularly minutely punctate, pubes-cence white below, golden above, sparse.Pronotum wider than long, widest at base, constricted at apex; anterior margin nearlytruncate; basal margin sinuate, median lobe emarginate in front of scutellum; disk convex, withstrong lateral depression each side, prehumeral carinae obtuse; surface with round glabrous areaeach side of median line, punctures on rest of area minute, white and golden pubescence sparse.Scutellum triangular, wider than long, glabrous.Elytra wider than base of pronotum; sides strongly constricted back of base, expanded backof middle, then strongly converging to broadly rounded, minutely serrulate apices; disk convex,with deep basal depression each side at middle of each elytron, umbone prominent, a lateralcarina extending from base to near apex; surface sparsely, irregularly, lightly punctate withthree transverse patches of white and golden pubescence separated by glabrous areas.Abdomen sparsely, finely punctate, pubescence short, sparse; apex of last ventral abdominalsegment truncate, margin strongly dentate, suture truncate, with a row of longer hairs alongfront margin.Length 4 mm; width 1.9 mm.Holotype 9 and paratype labeled Chiricahua Mountains, Ariz., June 17, 1939, collectedfrom oak foliage by D. J. & J. N. Knull.This species should stand next to B. cephalicus Schaeffer. It can be separated by lack ofstiongly convex tubercles above eyes. The markings are similar to those of B. aeruginosusGory, from which it can be separated by the retracted front and elongate form.REFERENCESCazier, M. A. 1951.
