466 Memoirs on the Coleoptera 



Anacentrus oklahomae n. sp. — Oblong-oval, convex, black, the elytra 

 piceous, the legs and beak rufous; upper surface with fine, hair-like and 

 very sparse vestiture, slightly more evident toward the thoracic sides, 

 in a single very inconspicuous series on the strial intervals, but with a 

 denser spot of whitish squamules at the base of the third, and having 

 very coarse, loose punctures throughout the under surface, each enclosing 

 a very small and slender squamule; beak in the male slender, perfectly 

 cylindric, minutely, sparsely punctulate, feebly and evenly arcuate and 

 as long as the head and prothorax, the antennae at three-fifths; prothorax 

 fully a third wider than long, the sides parallel, evenly and moderately 

 arcuate, rapidly transversely rounding apically to the large and strongly 

 tubulate apex, which is much more than half as wide as the base: punc- 

 tures coarse, less so and well isolated medially but coarse and longitudi- 

 nally confluent laterally, forming anastomosing rugae; scutellum very 

 small, nude, black; elytra just visibly wider than the prothorax and twice 

 as long, elongate, ovulate, not very obtusely rounded at apex; humeral 

 swellings feeble, the mes-epimera distinct from above, the grooves rather 

 fine, somewhat deep; intervals twice as wide as the grooves to more, each 

 with a single series of moderate, well separated and distinct punctures; 

 abdomen of the male deeply impressed medio-basally. Length (cf ) 2.9 

 mm.; width 1.18 mm. Oklahoma (Atoka), — Wickham. 



This is another species allied to punctiger, but the elytra! strise 

 are finer, and the intervals — described as one-half wider than the 

 striae in punctiger — relatively much broader. The apex of the 

 prothorax, also, is more abruptly and strongly constricted and more 

 broadly tubulate. 



Anacentrus minuens n. sp. — Body very small, oblong-suboval, only 

 very moderately convex, scarcely shining, rufo-piceous in color, the 

 beak blackish; scales above yellowish-white and dense along the sides 

 of the prothorax and before the basal lobe, elsewhere fine, sparse, darker 

 and inconspicuous, on the elytra distinct on parts of the third and fifth 

 intervals, but otherwise darker and inconspicuous, though not much 

 smaller, rather sparse but distinct beneath; beak in the male slender, 

 distinctly punctulate, squamose at base, cylindric, very feebly but evenly 

 arcuate and not longer than the prothorax, the antennae near three- 

 fifths; prothorax a fourth wider than long, the sides parallel, evenly, 

 feebly arcuate, rounding and rapidly more convergent in less than apical 

 third, the tubulate apex four-sevenths as wide as the base; punctures 

 deep, even, moderately coarse and dense though clearly defined, the 

 median smooth line entire; elytra short, abruptly a good deal wider than 

 the prothorax, with rather prominent humeral swellings, three-fifths 

 longer, scarcely a fourth longer than wide, the sides subparallel in anterior, 

 ogivally rounded in posterior, half; grooves very moderate; intervals 

 two to three times as wide as the grooves, with moderate loose punctu- 

 ation; abdomen in the male narrowly and deeply impressed medio- 

 basally. Length (cf ) 2.2 mm.; width 0.9 mm. Arizona.
