502 Memoirs on the Coleoptera 



subquadrate, not tubulate, with truncate base and obsolete lobe 

 and fine, remote punctuation, except at the sides, the scutellum 

 small, free, subquadrate and feebly impressed, the elytra coarsely 

 striate, with flatter and non-rugulose intervals, the pygidium longer 

 and semicircular. Legs moderate, the tarsi even more dilated than 

 in Strongylotes . There are two known species as follows : 



Form parallel, rather broad and only moderately convex, black throughout, the 

 legs and tarsi also black; surface polished; beak not very slender, deep 

 black, polished, glabrous, finely, sparsely punctate throughout, with a small 

 fringe of squamules along the edge of the eyes and about two-thirds as long 

 as the prothorax; antennae obscure rufous, the scape almost attaining the 

 eye, the first funicular joint not quite as long as the next three, the second and 

 third more or less longer than wide, the outer joints not much inflated, setose, 

 the club small, oval and barely longer than the three preceding joints; 

 prothorax very nearly as long as wide, widest near apical third, where the 

 sides are strongly rounded to the apex, feebly converging and nearly straight 

 thence to a minute basal arcuation; apex half as wide as the base; punctures 

 in somewhat more than lateral sixth rather strong and deep but well sepa- 

 rated, this part clothed closely with slender yellowish squamules, the entire 

 remainder glabrous and with very fine, remote punctures, the median line 

 not prominent, smooth for a short distance medially; elytra two and two- 

 fifths times as long as wide, as wide as the prothorax and two and one-half 

 times as long, the sides parallel and straight, evenly, circularly rounding at 

 apex, the humeral swellings feeble, polished; striae strong, even, only slightly 

 coarser at apex, their close punctures bearing distinct pale squamules; 

 intervals nearly smooth, with irregular series of moderate deep loose punc- 

 tures, bearing squamules similar to those of the striae; under surface un- 

 equally squamulose, more closely toward the sides. Length 8.5-8.7 mm.; 

 width 2.35-2.55 mm. Brazil (Chapada). March and January. Two 

 specimens amplitarsis n. sp. 



Form nearly similar but smaller, rather more convex, black throughout, but with 

 obscure rufous elytra; vestiture nearly as in the preceding; beak similar, 

 three-fourths as long as the prothorax, minutely and remotely punctulate; 

 antennae blackish-piceous, the first funicular joint very nearly as long as the 

 next three, the second slightly, the third not at all, longer than wide, the 

 club almost similar, abrupt, its basal segment nearly half the mass; prothorax 

 slightly shorter than wide, strongly inflated and widest just beyond the 

 middle, the sides thence convergent and feebly sinuate basally, broadly 

 rounded anteriorly; apex similarly non-tubulate, rather more than half as 

 wide as the base; punctures and vestiture arranged almost similarly, but 

 everywhere still finer and sparser; elytra parallel, as wide as the prothorax, 

 slightly wider than the base of the latter, evidently somewhat less than 

 three times as long, evenly rounded at apex; striae and general sculpture 

 nearly as in the preceding,. but less coarse throughout, the interstitial punc- 

 tures finer and more regularly uniserial; under surface nearly similar. 

 Length 6.7 mm.; width 1.8 mm. Brazil (Santarem). January. One 

 specimen lateralis n. sp. 



I can discover nothing in any of the specimens at hand, which 

 seems to be indicative of sex.
