Brazilian Baring 231 



as wide as the base; surface moderately but very densely and subconfluently 

 punctate, the median line smooth and finely carinulate; elytra evenly elliptic, 

 rather strongly rounded at apex, a fifth longer than wide, nearly a third wider 

 than the prothorax and about twice as long, the humeri very slightly prominent; 

 striae coarse and deep, the punctures indistinct, bearing fine squamules; intervals 

 about twice as wide as the stria?, densely and confusedly punctate; abdomen 

 strongly convex, somewhat closely punctate and unmodified basally in the type. 

 Length 3.6 mm.; width 1.8 mm. Brazil (Chapada — forest). November. A 

 single female specimen. 



This genus is undoubtedly rather closely allied to Forandia, but 

 the body is much smaller, with differently sculptured and pubescent 

 head and basal parts of the beak, much smaller eyes, different 

 mandibles and thoracic apex, very different scutellum, though with 

 similar basal thoracic lobe and, finally, the femora in Forandia are 

 rather strongly inflated; they are wholly uninflated here. At the 

 same time, it may be found expedient to unite the two genera as 

 subgeneric groups eventually. 



Centrinaspidia n. gen. 



The body here is small, rhombic-oval, clothed loosely and very 

 evenly with small slender whitish squamules, broader, closer and 

 more conspicuous on the under surface and especially broad and 

 dense on the met-episterna. Beak in the female very slender, 

 smooth and shining, dilated apically and rapidly thick and strongly 

 sculptured basally, the mandibles somewhat as in the preceding 

 but with the even inner edges slightly arcuate distally, the apex 

 acute and the outer angle beyond the middle feebler and more 

 obtuse, the apex of the beak above the mandibles broadly and 

 sharply angulate, not medially notched as in Forandiopsis; it is 

 separated from the "head by an extremely feeble depression. An- 

 tennae between basal third and fourth, with loosely jointed and 

 slender funicle, having the first joint as long as the next two and 

 thicker, the second and third also elongate, the club abrupt, oval 

 and nearly as long as the four preceding joints. Eyes well devel- 

 oped. Prosternum flat, squamose, separating the coxae by half their 

 width. Femora slender, the prothorax not tubulate at apex, the 

 scutellum small, oblong, sculptured, subglabrous, sinuate at apex 

 and narrowly canaliculate, the elytra deeply grooved. The type 

 is as follows : 



Centrinaspidia mundula n. sp. — -Rhombic-oval and slightly shining, convex 

 and deep black throughout ; beak ( 9 ) subevenly and moderately arcuate, a 

 fourth longer than the head and prothorax; antennae piceo-rufous; prothorax 

 two-fifths wider than long, the sides moderately converging, broadly and sub- 

 evenly arcuate from base to apex, the latter truncate and distinctly less than 

 half as wide as the base, the basal lobe small, rather strongly rounded; surface 

 strongly, very evenly and densely punctate, with a narrow flat median impunctate
