NEW AMERICAN SCOLYTOID BEETLES — BLACKMAN 389 



ly long, semierect, yellow setae, at sides directed caudad, setae finer 

 and directed mesad on disk. 



Elytra wider than pronotum and 1.82 times as long, 1.31 times as 

 long as wide; anterior margins arcuate, crenulate, with a secondary 

 row of lunate asperities behind and parallel to it, and a few addi- 

 tional, scattered asperities behind this; sides straight and subparallel 

 on anterior two-thirds, rather narrowly rounded behind, with pos- 

 terior margins serrate; surface somewhat shining; striae wide and 

 deep, with coarse, close punctures ; interspaces usually narrower than 

 striae, rugose, with low, wide, lunate, approximately uniseriate as- 

 perities; vestiture of rather stout, suberect setae, approximately uni- 

 seriate on disk and sides except in sutural interspaces. Declivity 

 arched, arising from well behind middle; striae deeper than on disk 

 and similarly punctured ; interspaces narrower, strongly convex, some 

 of asperities reduced to granules, others elevated to form sharp, coni- 

 cal teeth on interspaces 3, 5, 7, and 9; setae larger and more num- 

 erous than on disk. 



Male. — Similar to female, but with frons concave from above level 

 of eyes to epistomal margin, interantennal elevation incomplete in 

 median third; antenna similar to that of female but with longer, 

 more numerous hairs on scape. 



Type locality. — Aguaray and Tartegal, Argentina. 



Host. — Unknown. 



Type material. — Holotype, allotype, and 8 paratypes, U.S.N.M. No. 

 56566. 



The type series was collected by G. L. Harrington on October 19-21,

Plate 17, Figukes 35, 36 



Female. — Reddish brown, with head piceous-brown ; 2.53 mm. 

 long, 2.16 times as long as wide. 



Frontal rectangle 0.71 as long as wide, including epistomal lobe, 

 which is longer than wide ; frons (fig. 36) convex above, reddish, closely, 

 moderately coarsely punctured ; transversely impressed below ; elevated 

 between antennal bases, transversely flattened above, median line 

 with a carinal elevation which in turn has a median sulcus ; vestiture 

 short, fine, and sparse. Eye elongate elliptical. Antenna inserted at 

 side near eye; scape and funicle light reddish brown, club darker, 

 with segments less than twice as wide as long. 



Pronotum 1.17 times as wide as long, widest at base, posterior outline 

 scarcely sinuate, not at all extended posteriorly, posterior angle scarcely 

 rounded; sides convergently arcuate, with little evidence of anterior 

 constriction, anterior margin very broadly rounded, subsinuate in me-
