410 Memoirs on the Coleoptera 



9 — Form oblong-oval, convex, shining, deep black throughout; beak in the type 

 rather thick and closely sculptured, strongly arcuate distally but less so 

 basally, not separated by an impression and fully a third longer than the 

 head and prothorax, the latter rather strongly convex in profile, well devel- 

 oped, fully a third wider than long, the sides feebly converging and scarcely 

 arcuate, broadly rounding and oblique beyond the middle, the subobsolete 

 tubulation — though indicated as usual by the transverse dorsal impression — 

 much less than half as wide as the base; punctures remote and very minute, 

 becoming less remote and rather distinct toward the sides, the basal lobe 

 feebly truncate medially; elytra with evidently though slightly oblique and 

 but feebly arcuate sides and very broadly obtuse apex, a fifth longer than 

 wide, slightly wider than the prothorax and only about three-fourths longer, 

 the humeri distinctly prominent; grooves only moderately fine, somewhat 

 crenulate, very little stronger basally and at apex; intervals not very polished 

 and with single series of minute but evident remote punctures; pygidium 

 nearly as in the preceding; tibiae mutic. Length 2.1 mm.; width 1.1 mm. 

 Brazil (Chapada). March. One specimen, of undetermined sex. 



devinctus n. sp. 



Form much narrower, the size smaller, the prothorax relatively shorter and the 

 elytra longer, black, shining; beak in the type much more slender and less 

 sculptured, not separated by a distinct impression, rather strongly bent, 

 straighter basally and nearly one-half longer than the head and prothorax, 

 the latter two-fifths wider than long, in outline and punctuation nearly 

 similar; elytra a third longer than wide, subsimilar in form but less broadly 

 obtuse at apex, with similar humeri, slightly wider than the prothorax 

 and distinctly more than twice as long; subapical umbones subobsolete as 

 usual in the genus; surface less declivous at tip than in the preceding and 

 almost similarly sculptured, except that the intervals are narrower and with 

 the punctuation more minute and less remote; pygidium still smaller, 

 transverse; femora still more slender, mutic. Length 1.7 mm.; width 0.75 

 mm. Brazil (Chapada — forest). November. One example, probably fe- 

 male minutus n. sp. 



In Ampeloglypter ater Lee, the general structure is very much as 

 in these smaller tropical species, but the beak is rather thicker and 

 distinctly separated by an impression and the femora are mutic; 

 there seems to be only a limited group of the Brazilian species 

 having the femora partially armed, however. In ater, almost the 

 entire under surface, including the propleura, is very densely 

 sculptured, but with the punctures less individually defined on the 

 portions having this form of sculpture, than in the above species. 



Solariopsis n. gen. 



In some respects this genus is allied rather closely to Ampelo- 

 glypter, differing, however, very much in the regularly oval form of 

 the body, strong dorsal punctures and striation and more widely 

 separated anterior coxae. The very broad and feebly convex 

 posterior lobe of the prosternum extends almost to the line through 

 the middle of the intermediate coxae, and the surface before the 

 anterior coxae is flat, having, near the apex, a large and transversely
