310 Memoirs on the Coleoptera 



rufous; prothorax about a sixth longer than wide, the sides parallel and straight, 

 rapidly becoming oblique and straight in apical third, the truncate apex almost 

 three-fourths as wide as the base; punctures coarse, deep and dense, though not 

 quite in actual contact, each puncture with an infinitesimal squamule, the median 

 line anteriad irregularly smooth; surface with clustered white scales at the hind 

 angles and also a few along the base medially; elytra slightly more than one-half 

 longer than wide, as wide as the prothorax and three-fifths longer, the humeri 

 slightly tumid; sides parallel and straight, arcuate and oblique posteriorly to 

 the narrowly obtuse apex, with feebly reentrant sutural angle; intervals less 

 than twice as wide as the striae, each with a single series of moderate punctures, 

 bearing long and distinct white squamules; under surface with coarse punctures, 

 bearing slender white squamules, closer on the met-episterna, the abdomen smooth 

 and minutely, remotely and feebly punctulate. Length 2.2 mm.; width 0.65 

 mm. Brazil (Santarem). A single female specimen. 



Easily identifiable by the elongate non-tubulate prothorax, rather 

 large eyes, strong sculpture and evenly cylindric form of body. 



Anatorcus n. gen. 



This genus is also necessitated by a small cylindric and closely 

 sculptured species, having isolated structural characters. The beak, 

 probably in the male, although there are no abdominal modifica- 

 tions, is short and notably thick, not separated by a distinct im- 

 pression, the antennae at apical third, the scape about as long as 

 the funicle and almost attaining the eye, the funicle rather thick, 

 the outer joints compact and gradually wider, the first thick and 

 nearly as long as the next three, which are short, wider than long 

 and compact, the outer joints pallidly setulose, the club relatively 

 large, elongate-oval, slightly abrupt, truncate at base, as long as 

 the five preceding joints and with its subcylindric basal segment 

 distinctly more than half the mass. The eyes are moderate and 

 widely separated as usual. The prosternum is flat, separating the 

 rather small coxae by three-fourths their width; the legs are short 

 but of the usual structure. Prothorax with obsolete basal lobe, 

 the scutellum small, free, subquadrate, narrowed at base and sinuate 

 at apex, flat and glabrous, and the elytra are strongly striate. The 

 type is the following: 



Anatorcus densus n. sp. — Cylindric, moderately convex, deep black throughout, 

 the legs obscure rufous; squamules white, slender and sparse, evenly distributed 

 above and in single interstitial series, slender and sparse beneath, rather denser 

 and coarser on the prosternum, also dense on the narrow met-episterna; beak 

 four times as long as thick, two-thirds as long as the prothorax, strongly, some- 

 what closely punctate and loosely squamulose, the antennae piceous; prothorax 

 evidently longer than wide, very briefly and feebly subtubulate at apex; sides 

 parallel and very feebly, evenly arcuate, only a little more so toward the tubula- 

 tion, which is truncate and two-thirds as wide as the base; punctures strong and 

 rather close, though separated, the smooth median line broad, narrow apically 

 and not quite attaining the base; elytra fully three-fourths longer than wide, 

 just visibly wider than the prothorax and four-fifths longer, the humeri feebly
