AMARIN^E 241 



rounded; elytra similar in outline and relative size, but differing in 

 having all the striae rather fine and much more finely punctate, the 

 flat intervals becoming more noticeably convex at apex; lateral 

 series less broadly interrupted. Length (9) 9-O mm.; width 3.9 

 mm. New Mexico deceptus n. sp. 



5- Upper surface in both sexes highly polished, as though glazed, the 

 elytra in the female without trace of alutaceous lustre or minute 

 sculpture. Body oblong-suboval, convex, deep black above and 

 beneath, the extreme abdominal tip rufous; legs rufous throughout: 

 head moderate, barely over half as wide as the prothorax, the eyes 

 moderately prominent; strioles fine, very oblique; antennae slender, 

 ferruginous, not quite as long as the head and prothorax, the latter 

 widest at about the middle, short, three-fifths wider than long, the 

 apex very feebly sinuate, with rounded angles and barely three- 

 fourths as wide as the base, which is transverse; sides evenly rounded 

 from apex to base, the angles distinctly more than right, not rounded 

 and not at all prominent, the margins finely reflexed; surface im- 

 punctate, except finely and sparsely at base, the median stria very 

 fine and feeble; foveae shallow, the inner linear, the outer short and 

 suboblique; elytra slightly more than one-half longer than wide, 

 about three times as long as the prothorax and somewhat wider, 

 the parallel sides broadly, subevenly arcuate; striae extremely fine, 

 unimpressed, minutely punctate suturally, impunctate elsewhere, 

 the scutellar rather long, nearly free; lateral series more or less nar- 

 rowly interrupted; sinus small and shallow; under surface subim- 

 punctate throughout. Length (9) 7.5 mm.; width 3.35 mm. Ari- 

 zona (Tucson), Tucker specularis n. sp. 



Upper surface shining but less glazed, the elytra alutaceous and distinctly 

 micro-reticulate in the female 6 



6 Body oblong-suboval, convex, black, the abdomen rufescent apically, 

 the legs piceo-rufous; head slightly more than half as wide as the 

 prothorax, with prominent eyes and narrow oblique strioles; anten- 

 nae ferruginous, much shorter than the head and prothorax, the 

 latter large, widest at about the middle, barely two-fifths wider than 

 long, the apex deeply sinuate, with rather narrowly blunt angles, 

 much narrower than the base, which is rectilinear; sides finely but 

 abruptly reflexed, evenly arcuate from apex to base, the basal angles 

 distinctly more than right, not rounded and not prominent; surface 

 with obsolete impressions, sparsely punctate apically and basally, 

 the foveae shallow, more punctate, the inner sublinear, the outer 

 smaller and rounded, distant from the base as usual in this subsec- 

 tion; elytra widest at the middle, scarcely one-half longer than wide, 

 parallel, with rather strongly and evenly arcuate sides, almost a 

 fifth wider than the prothorax, the humeri not exposed, minutely 

 denticulate; striae rather fine but deep, not impressed, finely punctu- 

 late anteriorly, the scutellar moderate; lateral series moderately 

 interrupted; intervals flat, alutaceous (9 ). slightly less flat apically; 

 sides of the metasternum, met-episterna and latero-basal parts of 

 the abdomen finely, sparsely punctulate; anterior tibiae with five
