9. Cyrea viola Canepari and Gordon , new species

Description. Male holotype. Length 3.7 mm, width 2.8 mm; body elongate oval, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except head with clypeus black and triangular macula at base of eye black; pronotum black with large, diamond shaped yellow spot medially, anterolateral angle deeply emarginate by yellow spot; elytron black with 3 yellow vittae, sutural vitta widened at base, slender posteriorly to apical 1/10, connected to median and lateral vittae at apex, median vitta slightly enlarged basally, extended posteriorly to apical 1/10, vitta on lateral margin of elytron narrow throughout, extended from humeral angle posteriorly to connection with other elytral vittae ( Fig. 43 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen dark brown except slightly paler laterally and apically. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures smaller than on elytron, separated by about a diameter medially, larger, denser in lateral 1/3. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin curved, smooth, sponda not extended beyond oblique angle. Carinae on prosternal process widely separated at apex, slightly convergent medially, apex rounded and joined at basal 1/6 of prosternum, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex. Ventrites 1-2 with sparse, long pubescence and coarse punctures medially becoming smaller and denser laterally; ventrites 3-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate, nearly truncate; 6th ventrite medially depressed, apex weakly emarginate. Apical tergite finely, densely punctured, apex deeply, widely emarginate, lateral angle broadly produced, rounded. Genitalia with basal lobe 3/4 as long as paramere, wide, asymmetrical, sides parallel to bifid apex; paramere Unm, wide throughout, widened from base to rounded apex ( Fig. 44, 45 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, narrow, apex slightly rounded, outer arm curved, longer and wider than inner arm, with accessory piece, basal border shallowly, widely emarginate ( Fig. 46, 47 ).

Female. Similar to male except head entirely black with median, apically bifid yellow macula at base of frons. Genitalia elongate, about same width throughout, apex of cornu rounded; bursal cap oval with 2 sclerotized arms, apical strut long, apical 1/3 abruptly widened to racket shape ( Fig. 48 ).

Variation. None observed.

Type material. Holotype male; Colombia, Boy (Boyaca), 2520, Santa Rosa, Dec.18.1941, Murillo No 5427. ( USNM) . Paratype; 1, Colombia, Boy , Santa Rosa, Alt. 1520m., 18-XII-47, Murillo No 5427 ( USNM) .

Remarks. This handsome species is readily recognized by the large size, vittate elytron, and Colombian type locality.
