deeply cribrate, as in many of the Ampeloglypterids, the coxae well 

 separated. The legs are moderate, the third tarsal joint but feebly 

 dilated and the claws undoubtedly fused together at base. The 

 prothorax is long, gradually tubulate at apex and with very small 

 short basal lobe, which is truncate at apex, the scutellum fiat, 

 closely-fitted, scarcely as wide as long and rounded, and the elytra 

 with fine grooves, which are only a little coarser or more impressed 

 at apex. The pygidium is rounded and twice as wide as long, the 

 first abdominal suture obsolete medially. The only species known 

 to me is the following: 



Linomaspis picea n. sp. — Subventricose, convex, moderately shining and piceo- 

 rufous throughout, glabrous; beak (o 71 ) nearly as long as the head and prothorax, 

 the latter very nearly as long as wide, the sides feebly converging and almost 

 straight, rapidly becoming oblique in apical two-fifths to the tubulation, which 

 is much more than half as wide as the base; punctures rather small but perforate, 

 separated by nearly twice their diameters and subsimilar in size and separation 

 throughout the pronotum, but with a distinct smooth median line; elytra oblong- 

 oval, between a fourth and third longer than wide, with only very feebly oblique 

 and slightly arcuate sides and rapidly broadly obtuse apex, the humeri small 

 and feeble, fully a fourth wider than the prothorax and much more than twice as 

 long; grooves fine, feebly punctulate, gradually coarser basally, the intervals 

 with single series of moderately distant infinitesimal punctules; under surface 

 with rather close, moderate, deeply perforate punctures, very dense toward the 

 sides of the abdomen posteriorly; male with a small but deep and simple impres- 

 sion at the middle of the abdomen toward base. Length 2.9 mm.; width 1.25 

 mm. Brazil (Chapada — forest). September. A single specimen. 



The very obtuse elytra and correspondingly obtuse abdomen, and 

 the peculiar punctures — small in size but deep, perforate and con- 

 spicuous, are additional tokens of affinity with Ampeloglypter. 



Anagivenius n. gen. 



In some respects this genus might be regarded as related to 

 Eugivenius, but in general structure it is very different. The body 

 is rather stout, convex and more Or less densely and very strongly 

 punctate and glabrous. Beak short, rather finely, densely punctate, 

 smoother distally. Antennae medial or post-medial, short, the first 

 funicular joint in the type nearly as long as the next three, 2-7 

 transverse and compact, gradually increasing, the club oval, as long 

 as the six preceding joints, with its first segment nearly half the 

 mass. Prosternum broadly canalate, the canal rather shallow but 

 sharply limited and having, at its anterior end, a small deep fovea 

 at each side, homologous in this respect with Glyptobaris, the coxae 

 separated by nearly their own width, the posterior lobe short and 

 broadly arcuate. Prothorax very briefly tubulate, the basal lobe 

 short, gradual and obtuse. Scutellum free, subquadrate, impressed 

 and finely sculptured, except narrowly at the sides, the elytra
