NO. 9 GENUS CHLAENOBIA BLANCHARD CHAPIN IJ 



Material examined. — Type (male) and three paratypes (males 

 and females) from above locality, collected from June lO-July 30, 

 Kusche. 



The extremities of this species are miusually pilose in the male, 

 the posterior femora at base and posterior tibia at apex bear dense 

 brushes of long hair on their inner margins. All tarsi are also ex- 

 ceedingly pilose.

Chlacnobia aequafa Bates, 1888, Biol. Centr.-Amer., Coleopt., vol. 2, pt. 2, p. 168. 



Head coarsely punctured, densely so on vertex and upper portion 

 of frons, moderately densely so on clypeus and very sparsely so on 

 lower part of frons in the region of the clypeofrontal suture which is 

 strongly impressed and bisinuate ; clypeus with marginal fourth re- 

 flexed, the central portion nearly flat, the margin slightly notched at 

 middle. Antenna ten-segmented. Pronotum transverse, side margins 

 strongly angulate at middle, lateral margin strongly sinuate near pos- 

 terior angle as viewed from side, viewed from above, the anterior 

 angles are obtuse and rounded, basal angles prominent and subacute ; 

 punctures coarse, more sparsely placed on disk than on flanks where 

 their density is similar to those on clypeus. Scutellum equilateral, the 

 side margin curved, surface sparsely and rather finely punctured near 

 margins. Elytra with sutural margins broadly tumid except at apex 

 where the extreme margins are sharply carinate, discal costae not 

 evident, punctures less coarse but as densely placed as on flanks of 

 pronotum, epipleura very narrow. Metasternum moderately coarsely 

 and very densely punctured at sides, a little more sparsely so in median 

 portion. 



Male. — Antennal club almost as long as all the remaining segments 

 combined. Fifth sternite with a sparse patch of hair at middle, arising 

 from a patch of asperities, sixth sternite tumid with a central de- 

 pression surrounded by a few very coarse punctures or pits, free 

 margin with a broad and not very prominent process. Pygidium 

 uniformly and strongly convex, coarsely and sparsely punctured, a 

 little more densely so toward base ; apical margin sharply and narrowly 

 reflexed. Anterior tibia bidentate with a faint indication of a third 

 tooth. Second segment of anterior tarsus narrow with parallel sides, 

 about four times as long as broad. Aedeagus, figure 9. 



Female. — Antennal club as long as second to seventh segments 

 combined. Sternites not noticeably modified. Pygidium elongate 

 triangular, basal half evenly convex from side to side, apically
