Brazilian Baring 337 



fully half the length, the sutures distinct. The prosternum is flat 

 and unmodified, strongly punctate and separates the coxae by^ their 

 own width, the legs moderate and simple, the fourth tarsal joint as 

 long as the three preceding together, the claws rather long, straight 

 and basally connate. The prothorax is not at all tubulate at apex 

 and has a small, evenly rounded basal lobe, the scutellum small, 

 free, subquadrate, convex and somewhat sculptured and the elytra 

 deeply grooved; the tip of the last dorsal segment is slightly visible 

 in the obtuse reentrant angle between the broadly rounded apices. 

 The type can be described as follows: 



Cropelia punctata n. sp. — Rather stout, evenly oval and convex, somewhat 

 shining and deep black throughout; beak equal in length to the prothorax and 

 cylindric in the type, the antenna; blackish; prothorax large, only a sixth wider 

 than long, the sides evenly arcuate, becoming gradually parallel at base, the 

 truncate apex about half as wide as the base; punctures coarse, deep, even and 

 only slightly separated, without median line; elytra short, only a fifth or sixth 

 longer than wide, oval, the rapidly obtuse apex half as wide as the base, equal in 

 width to the prothorax and only one-half longer; grooves deep, becoming gradu- 

 ally coarser and coarsely punctate basally; intervals rather narrow, each with a 

 single series of moderate but deep and distinct, very close-set punctures; ab- 

 domen convex, finely, loosely punctate, with a small feeble impression along the 

 median line of the first segment in the type. Length 2.25 mm.; width 1.0 mm. 

 Brazil (Santarem). One specimen. 



The type is probably a male, although the sexual characters are 

 very feeble. The species is not at all closely related to any other 

 at present known. 



Tonesia n. gen. 



The body in this genus is more or less depressed, shining, oblong- 

 oval and always glabrous. The beak is cylindric, moderately 

 arcuate, separated from the head by a distinct impression and is 

 subsimilar in the sexes in typical species of the genus, the mandibles 

 dentate and decussate. The antennae are submedial, but more 

 basal in the subulate beak of the female of the robustida section, 

 short, the first funicular joint stout, nearly as long as the next three, 

 2-7 short, not much wider distally, the oval club very abrupt and 

 subequally divided by the deep sutures. The prosternum is flat, 

 widely separating the coxae and, in the male of all except the robus- 

 tida section, has two strongly porrect spines. The legs are moderate 

 and simple, the tarsal claws free and divergent, the prothorax feebly 

 subtubulate at apex, the scutellum subquadrate, free and flat and 

 the elytra coarsely and deeply grooved. The species at hand are 

 the following: 



Beak subsimilar in the sexes; basal thoracic lobe very feeble and broadly arcuate 

 to almost obsolete, not sinuate; male prosternum armed, the spines sepa- 

 rated by a broad impression 2
