376 Memoirs on the Coleoptera 



Body larger, rather more broadly oval, convex and polished, black, the legs 

 piceous-black; head missing in the type; prothorax slightly longer than 

 wide, the sides less arcuate than in the preceding and nearly straight; apex 

 feebly sinuate medially as usual, four-sevenths as wide as the base; punctures 

 sparse, minute throughout; elytra evenly oval, not so obtuse behind, barely 

 over one-half longer than wide, evidently wider than the prothorax and 

 three-fifths longer, the humeri less tumid, only very feebly swollen; striae 

 very fine, almost obsolete, a little stronger but still very fine at apex, minutely 

 punctulate, the infinitesimal interstitial punctulation barely visible; pygidium 

 small, as long as wide, rounded, nearly flat and clothed rather closely with 

 slender parallel yellow squamules; first two ventrals behind and in line with 

 the coxa? equal in length and each nearly a fourth longer than either the third 

 or fourth in the same line, the fifth one-half longer than the fourth. Length 

 5.0 mm.; width 2.18 mm. Brazil (Santarem) congruens n. sp. 



7 — Body small, narrow and elongate-oval, polished, black, the legs rufous through- 

 out; antennae (0*) somewhat as in flavicornis, very pale, short, the funicle 

 similarly formed and bristling with even coarser setae, the club nearly similar; 

 first funicular joint shorter, not as long as the next two; beak ( 9) nearly 

 similar in form but almost as long as the prothorax, although actually of 

 less length, the flattened sides more finely sculptured; antennae nearly at 

 three-fourths; prothorax narrower, distinctly longer than wide, the sides 

 slightly arcuate anteriorly; punctures finer and sparser, especially toward 

 the sides; scutellum a little smaller; elytra ovoidal, obtuse at apex, three- 

 fifths longer than wide and about three-fifths longer than the prothorax; striae 

 similar but somewhat more strongly and remotely punctate, more strongly 

 impressed at apex than in flavicornis, the interstitial punctulation still more 

 minute and sparser; pygidium (cf) relatively larger, similarly convex but 

 more glabrous; anterior coxae separated by evidently more than their own 

 width. Length 3.65-3.75 mm.; width 1. 45-1. 5 mm. Guatemala (Vera 

 Paz), — Champion. Two specimens. [Lob. flavicornis Chmp. nee Gyll.] 



parvulus n. sp. 



The identification of flavicornis given above, is only tentative, as 

 it is impossible to be sure without an actual inspection of the type; 

 for example, in the description of Gyllenhal, the elytra are said to 

 be scarcely more than twice as long as the prothorax, whereas in 

 actuality they are much less than twice as long in the Chapada 

 specimens, and there are other inconsistencies; the legs in flavicornis 

 are definitely stated as black, whereas in parvulus they are rufous 

 throughout. The type of congruens is doubtless a female, so that 

 the absence of head is of but little moment. 



Madarus Schon. 



In this genus the body is oblong-oval, convex, polished and wholly 

 glabrous, the beak thick, subcylindric, feebly arcuate, separated 

 from the head by a broad shallow impression and similar in the 

 sexes; the mandibles are well developed, bifid and moderately 

 decussate. The antennae are at three-fifths (o 71 ), or just visibly less 

 apical ( 9 ), the scrobes deep and oblique, the scape far from attain- 

 ing the eye; the first funicular joint is as long as the next three,
