Biological Series, Vol. 15, No. 3 New Neotropical Scolytidae 39 posterior angles broadly rounded, anterior angles arcuately converging toward broadly rounded anterior margin; dorsal profile arcuate from base, a little more strongly declivous on anterior third; surface shining, with few points, punc- tures rather coarse, deep, separated by distances equal to width of a punctiire, lateral margin of each puncture very finely asperate, tubercles becoming larger laterally. Vestiture hairlike, inconspicuous except laterally and in asperate area. Elvtra times as long as wde, times as long as pronotuni; sides straight and parallel on slightly more than basal two-thirds, broadly rounded behind; striae not impressed, punctures large, deep; interstriae slightly wider than striae, almost smooth, shining, punctures two- thirds as large as those of striae, spaced one to two times diameter of a puncture. DecHvity steep, distinctly convex; posterolateral margin acutely elevated from apex to interstriae 7; striae weakly impressed; interstriae weakly convex, punctures reduced and feebly granulate. Wstiture consisting of erect, interstrial bristles. Fem.\le.—Similar to male except frons bear- ing a rather dense fringe of long yellow hair to well above eyes, except central area glabrous. Type LocALiTi'.—Rio Damitas in the Dota Mountains, San Jose Prov., Costa Rica. Type Material.—Tlie male holotype, female allotype, and 19 paratypes were collected at the tv'pe locality on 18 February 1964, at an ele- vation of 250 m, by S. L. Wood, from stems of an unidentified vine; 22 paratypes were taken at Playon, Puntarenas Prov., 22 February 1964, at 50 m elevation, by S. L. Wood, from a wild cucurbit vine. Xyleborus ebenus, n. sp. This species is very closely related to san- guinicollis Blandford; it is readily distinguished from that species by the black pronotum, by the shining elytral declivity, with strial pun
