1 6 Memoirs on the Coleoptera 



lineate scales rather sparse, slightly nucleated on the elytra, fulvous in color, 

 with a few white squamules at the sides of the elytra posteriorly, uniform on the 

 pronotum, minute and sparse everywhere beneath; beak a third longer than the 

 head and prothorax, feebly arcuate, shining and finely, rather sparsely punctulate, 

 closely so and squamulose basally; second funicular joint long, slender, the first 

 shorter and stout; prothorax but little wider than long, subparallel and nearly 

 straight at the sides, rounding and converging beyond the middle to the broadly 

 and gradually tubulate apex, which is arcuate and slightly more than half as 

 wide as the feebly and medially lobed base; median line with a shining biab- 

 breviated carina; surface finely, closely punctulate, impunctate and shining at 

 base, more broadly toward the sides; scutellum as long as wide, parabolic, feebly 

 punctulate and flat; elytra three-fourths wider than the prothorax, two-fifths 

 longer than wide, the sides nearly straight and converging to the moderately 

 obtuse apex, the humeri very prominent and the subapical umbo slightly so; 

 stria? rather coarse, deep; intervals 2, 3, 5 and 7 carinulate, the others flat, convex 

 on the flanks. Length (9)4-0 mm.; width 2.25 mm. Mexico (Orizaba). 



The Central American species such as 10-costata and 8-costata, 

 reticulata, cristata, and several others defined by Mr. Champion, 

 also belong to this genus, which is probably a large one, though 

 apparently confined to the Central American regions. The present 

 species differs much from any hitherto described in the even and 

 unvariegated nature of the thoracic vestiture and in some other 

 characters. 



Anones n. gen. 



In some respects this genus is rather close to the preceding, and 

 in a similar way has the antennae medial in insertion, the second 

 funicular joint longer than the first and the club subglobular and 

 pointed, with its basal segment more than half the mass; but here, 

 the body is more regularly oval, without prominent elytral humeri, 

 with broader, more basally inflated prothorax and more minute and 

 basally connate tarsal claws. The strial intervals also are all flat, 

 or with almost imperceptible carination and only on the upper part 

 of the flanks; the pronotum is even in convexity and not gibbous. 

 The type may be regarded as the first of those defined below : 



Scutellum rather well developed. Brazilian 2 



Scutellum notably smaller. Central American regions 3 



2 — Body very stout ; prothorax much inflated and strongly rounded at the sides. 

 Black, evenly suboval and convex; squamules whitish, narrow, sparsely and 

 unevenly disposed, more distinct in an oblique line near each side of the 

 pronotum and almost throughout intervals 4 and 6 on the elytra, moderately 

 close and uneven beneath, a denser point near apex and base of the pro- 

 thoracic flanks and at the sides of the mesosternum proper; beak rather 

 slender, longer than the head and prothorax, feebly arcuate, slightly tapering 

 and closely sculptured, smoother and more shining distally; prothorax 

 transverse, nearly three-fifths wider than long, the inflated sides strongly, 

 evenly arcuate, strongly converging anteriorly to the tubulate apex, which 

 is less than half as wide as the base; surface opaque, densely punctulate. 

 the median line not modified; scutellum a little wider than long, trapezoidal.
