Parareoda n. gen. 



In general characters the type of this genus is allied rather closely 

 to Cotalpa and Byrsopolis, but it differs from both in the triangular 

 and obtusely pointed clypeus. The upper surface is glabrous, the 

 under surface clothed very densely with long brown pubescence,, 

 shorter and sparser on the abdomen, and the pygidium is clothed 

 not densely with short and very stiff hairs. The basal bead of the 

 pronotum is interrupted medially and the mesosternal process is 

 obsolete, the coxae being very approximate; the prosternal process 

 is short and abruptly much curved forward at tip. The mentum 

 is concave anteriorly, the mandibles broadly rounded externally 

 and reflexed, not dentate internally; eyes small, the anterior 

 canthus with a very dense brush of stiff setae. The sculpture of 

 the upper surface is much coarser than in Cotalpa but the pronotal 

 punctures are correspondingly less coarse than in Pocalta, the elytra! 

 sculpture coarser than in either. From Byrsopolis, the genus 

 differs in the anteriorly angulate form of the clypeus, very feebly, 

 evenly arcuate and not notably flexuous clypeal suture and in- 

 visible mesosternal process. The antennal club in Byrsopolis is 

 notably long, being as long as the basal width of the clypeus in 

 castanea Burm., the Brazilian type species. The type of Parareoda,, 

 with which I associate also the recently described Byrsopolis ari~ 

 zones of Ohaus, may be defined as follows: 



Form oblong-elongate, convex, shining, castaneous in color throughout, 

 without trace of metallic reflection at any part, the legs concolorous; 

 upper surface glabrous, the metanotum however with a dense fringe 

 of brown hairs, which is very conspicuous medially, attaining the 

 base of the scutellum; head barely two-fifths as wide as the prothorax, 

 coarsely, deeply and confidently punctate throughout, the clypeus 

 flat, less than one-half wider than long, triangular, with nearly 

 straight sides, which are finely and barely at all reflexed, the apex 

 bluntly rounded and feebly reflexed; antennal club (9) much 

 shorter than the stem as in Cotalpa; prothorax a little less than twice 

 as wide as long, strongly convex, the sides viewed from above 

 broadly, subevenly arcuate, becoming subparallel in about basal 

 half, strongly converging apically to the well defined and subacute 

 angles, the basal angles slightly obtuse and narrowly rounded; 

 base broadly, feebly lobed, the marginal bead rather thin, reflexed, 

 elevated, broadly obsolete medio-basally, the apical bead, only visible 

 near the sides; surface strongly, sparsely and unevenly punctate, 

 densely anteriorly and very confluently near the sides; median line 

 finely subimpressed anteriorly; scutellum ogival, shorter than wide,
