Brazilian Barin^e 491 



Body smaller, elongate-oval, glabrous, polished and deep black throughout; 

 beak (o 71 ) longer and less thick, evenly, moderately arcuate and as long as 

 the head and prothorax, rather finely and sparsely but deeply punctate; 

 antennae piceous, slightly beyond apical third, more slender than in the 

 preceding, the funicular joints barely wider distally, the club nearly similar, 

 relatively small in size; prothorax a sixth wider than long, the sides more 

 strongly but broadly arcuate, becoming gradually subparallel and straighter 

 basally, the feeble short tubulation less than half as wide as the base; punc- 

 tures fine but deep, sparse, scarcely differing at the sides, the median line 

 almost similar; scutellum distinctly free, wider than long; elytra four- 

 sevenths longer than wide, at the feebly tumid humeri a fifth wider than the 

 prothorax, two and one-half times as long, the sides more oblique, broadly, 

 evenly arcuate, the apex more strongly, evenly rounded ; striae very different, 

 in the form of narrow and sharply defined smooth grooves, obsolete posteriorly 

 and laterally and there replaced by scarcely impressed series of small distinct 

 punctures, somewhat deeply grooved inside the feeble subapical umbones; 

 pygidium similar, the transverse carina even more distinct; male abdomen 

 with a small shallow impression at the centre of the first ventral, that of the 

 fifth transversely oval and very shallow. Length 5.6 mm.; width 2.5 mm. 

 Brazil (Santarem). One specimen striatus n. sp. 



The first of the above species resembles bonvouloiri Kirsch, the 

 more closely, but differs in its shorter and thicker beak, shorter and 

 broader thoracic tubulation and in the male modification of the 

 abdomen, the basal impression being much smaller, deeper and 

 more definite. 



Balbus Pascoe 



This genus is considered synonymous with Anopsilus by Mr. 

 Champion, but, though extremely closely allied, there are some 

 characters that seem to warrant a distinction. The general aspect 

 of the body, for example, is quite different, due to the rhombic 

 outline and the evenly conical non-tubulate prothorax of conicollis 

 Boh., the type of Balbus; the pygidium is not quite so short or 

 transverse, being circularly, though broadly, rounded beneath, but 

 it has a similar transverse carina, though much nearer the base. 

 The antennae are nearly similar in form and position and the beak 

 has a similar impression along the sides basally. The prosternum 

 is nearly similar, but the sides of the sulcus are tubercularly prom- 

 inent at the middle in the male. The legs and claws are almost 

 similar, but the tibiae are longer. The type is the following: 



Balbus conicollis Boh. — Elongate-rhomboidal, deep black, polished, glabrous 

 and extremely feebly sculptured; beak 'd") moderately thick, somewhat longer 

 than the head and prothorax, very feebly arcuate, more so distally, rather finely 

 but deeply, loosely punctate; antennae at three-fifths, piceous; prothorax a 

 perfect cone, about as long as wide, the sides barely visibly arcuate; apex only 

 three-sevenths as wide as the base, which is very feebly and gradually arcuate 

 medially; punctures extremely minute, feeble and remote, scarcely discoverable 

 and not differing at the sides; scutellum free, convex, smooth and transversely 

 quadrate; elytra fully two-thirds longer than wide, at the rather prominent
