14 — Antenna; thick, moderate in length, the club unusually broad, with its first two 

 joints distinctly transverse ; body very elongate and moderately convex ; prothorax 

 moderately transverse, less than one-half wider than long, the sides distinctly 

 converging and almost evenly, moderately arcuate from base to apex, the latter 

 distinctly narrower than the base ; disk feebly but almost evenly convex, finely 

 but strongly, rather closely punctured, with a more or less distinct impunctate 

 median line ; elytra oblong, parallel, elongate, fully three-fourths longer than wide, 

 only slightly wider than the prothorax, rather obtusely rounded in apical third, 

 finely but distinctly, rather closely punctured. Length 1.7-1.8 mm.; width 0.62- 

 0.65 mm. New Mexico (Coolidge) and Colorado forticornis, sp. nov. 



Antennse slender, the club narrow, with its first two joints but little wider than long, 

 moderate in length ; body smaller and less elongate but similar in coloration and 

 general characters \.o forticornis ; prothorax rather strongly transverse, fully one- 

 half wider than long, otherwise similar to forticornis but still more closely and 

 more finely punctured ; elytra three-fifths to two-thirds longer than wide, scarcely 

 wider than the prothorax ( <? ) or distinctly so ( 9 ) > ^^ punctures fine but strong 

 and very close-set, the pubescence very short but coarse. Length 1.5 mm.; width 

 0.55 mm. Arizona (Williams) — Mr. Wickham macer, sp. nov. 



15 — Pronotum distinctly impressed at base, the impression abruptly limited to about 

 median half of the width, the surface before the impression never tumid at the 

 middle 16 



Pronotum distinctly impressed but more broadly and indefinitely, the impression ex- 

 tending from side to side 17 



Pronotum not impressed at base, other than the fine line rendered apparent by the fine 

 basal bead 24 



16 — Body very elongate-oval, narrow, rather convex, polished, pale flavo-testaceous 

 throughout, the pubescence very short, sparse and inconspicuous ; antennae rather 

 short and thick, the club broader than usual, short, with its first two joints strongly 

 transverse ; prothorax not quite one half wider than long, the sides prominent 

 near basal third, strongly convergent thence to the base, and, feebly, nearly to 

 the apex, where they are rounded ; punctures fine, but strong and rather sparse ; 

 elytra parallel, elongate, moderately obtuse at apex, slightly wider than the pro- 

 thorax, very finely and quite sparsely punctate, the punctures strongly tending to 

 serial arrangement. Length 1.75 mm.; width 0.7 mm. California (Sonoma 

 Co. ) ochronitens, sp. nov. 



Body much smaller, elongate-oval and narrow, less shining and rather less convex, 

 dark rufo-testaceous throughout ; antennae moderately developed, more slender, 

 the club narrow, with its two basal joints but feebly transverse ; pubescence very 

 short, moderately sparse ; prothorax moderately transverse, the sides distinctly 

 sinuate just behind the middle, but not very prominent behind the sinus, thence 

 converging strongly to the base, converging and rounded at apex, the latter but 

 little narrower than the base ; disk rather depressed, quite strongly and closely 

 punctate, the basal impression strong ; elytra rather less elongate, about two- 

 thirds longer than wide, slightly wider than the prothorax, gradually rather ob- 

 tusely I'ounded behind, the punctures strong and moderately close-set, not tend- 

 ing to linear arrangement. Length 1. 5 mm.; width 0.65 mm. California 

 (Siskiyou Co.) undulata, sp. nov.
