NEW AMERICAN SCOLYTOID BEETLES — BLACKMAN 391 



El3i^ra wider than pronotiim and 1.92 times as long, 1.31 times as 

 long as wide ; sides subparallel on anterior two-thirds, rather broadly 

 rounded behind; basal margins from suture to fifth interspace with 

 &-7 crenulations on ea^-h elytron, in a continuous line ; striae impressed, 

 much stronger behind, punctures moderately large, close ; interspaces 

 wider, moderately convex, with numerous fine punctures bearing small, 

 subcircular, appressed scales, with a median row of larger punctures 

 bearing larger, narrower, erect scales in each interspace; scales vary- 

 ing in color from nearly white to testaceous, but not forming a color 

 pattern. Declivity evenly arched, not modified, scales slightly longer 

 and more erect than on disk. 



The male is unknown. 



Type locality. — Ocho Kios, Jamaica.

Genus CHRAMESUS LeConte 



CHRAMESUS PANAMENSIS, new species 



Feinale. — Dark reddish brown to piceous, opaque, with yellow- 

 cinereous bristles and scales ; 1.43 mm. long, 1.70 times as long as wide ; 

 allied to hicoriae LeConte and asjyeratus Schaeffer, but smaller than 

 either of these. 



Frons convex above, flattened below, with epistomal lobe nearly 

 as long as wide arising from the liplike epistomal margin; frontal 

 rectangle (including lobe) 1.16 times as long as wide; surface opaque 

 to subopaque, reticulate, very finely granulate, with minute punctures 

 bearing short, moderately stout, dorsally directed hairs. Antenna 

 arising from side near eye, similar in general to that of hicoriae. Eye 

 rather large, facets moderately large, inner line entire. 



Pronotum 1.24 times as wide as long, posterior outline bisinuate, 

 moderately produced in median line; sides strongly arcuately con- 

 vergent, broadly rounded in front; feebly, transversely impressed 

 just behind front margin ; surface opaque, reticulate, finely granulate- 

 punctate in median area, lateral areas with low, broad asperities par- 

 allel to lateral outlines and extending to base; entire surface with 

 rather sparse, flattened, cinereous setae directed posteromesad on disk. 



Elytra wider than pronotum and 1.50 times as long, 1.12 times as 

 long as wide ; bases arcuate, elevated, and serrate ; sides feebly arcuate, 

 broadly rounded behind; dorsal contour obliquely arcuate from base 

 to apex ; surface opaque to subopaque ; striae impressed, with shallow, 

 moderate-sized punctures ; interspaces much wider than striae at base,
