28 Memoirs on the Coleoptera 



Tripestes scutellatus n. sp. — Form oval, only faintly rhombic, convex, black, 

 the antennae dark piceous; vestiture of the pronotum of fulvous, finely hair-like 

 squamules, well separated, subdenuded in a broad line at each side of the middle, 

 white toward base of the median line and in a few minute points in a transverse 

 median line; scutellum transversely triangular, glabrous, the median part being 

 an oblong parallel truncate area, which is extremely densely clothed with pure 

 white squamules; elytra irregularly variegated, having fine and sparse squamules, 

 mostly fulvous, two white marginal spots on each behind the middle being more 

 conspicuous; under surface with close white squamules, very dense throughout 

 the first two abdominal segments, the remainder of the abdomen abruptly gla- 

 brous and shining, excepting a few scales at the extreme sides; beak moderately 

 thick, feebly arcuate, shorter than the head and prothorax, finely, not densely 

 punctate, the antennae slightly behind the middle, the first four funicular joints 

 moderately elongate, somewhat decreasing in length; prothorax conical, slightly 

 wider than long, the sides only feebly arcuate; apex sulcate on the flanks, arcuate, 

 less than half as wide as the base, the basal angles rounded, the lobe broadly 

 rounded; surface strongly gibbous, highest behind the middle, the median line 

 a shining low carina; punctures rather fine, very densely longitudinally confluent; 

 elytra a sixth longer than wide, a fourth wider than the prothorax, obtusely oval, 

 with broadly and feebly rounded humeri; striae moderate but deep; intervals 

 closely punctulate, 3, 5, 7 and 9 strongly carinate almost throughout, the others 

 flat; abdomen not concave at base. Length (9) 4.3 mm.; width 2.4 mm. 

 Brazil (Rio de Janeiro). November. One example. 



To be distinguished at once by the oval form, gibbous pronotum, 

 very remarkable scutellum and strong, rather even carination of 

 the alternate strial intervals; also by the bipartite abdomen as 

 described above. 



Eurypages Pasc. 



The two following genera depart conspicuously from those that 

 precede by the notable separation of the anterior coxae, though in 

 general features they conform very well, and I have no doubt are 

 best placed in the Optatini. In the present genus the body is of 

 large size, oval, feebly subrhombic in outline, with convex surface, 

 long and very nearly straight beak, moderately thick, strongly 

 inferiorly dentate femora, fluted tibiae and thick connate tarsal 

 claws. The anterior legs are longer and with more dilated and 

 fimbriate tarsi in the male. The scutellum is transverse, emarginate 

 at base, rather convex, coarsely, sparsely punctate and medially 

 squamose, its surface and the angulate cuspidiform apex as in 

 Lydamis and some other genera of this tribe. The single species 

 in my collection may be described as follows : 



Eurypages rectirostris n. sp. — Not very broadly suboval, convex, with deep 

 black integuments and antennae; vestiture above of large linear ochreous-yellow 

 squamules, fine and sparse on the pronotum, except in denser areas along the 

 median line and indefinitely at the sides anteriad and posteriad; elytra with the 

 squamules close-set, forming a very irregular curved subbasal and broader slightly 

 post-median fascia and large apical spot, also a few areas laterally between the 

 two fasciae, elsewhere finer and sparse, all the squamules arranged obliquely on
