CHLAENOBIA ARROWI, n. sp. 



Head coarsely and moderately densely punctured on frons, vertex 

 virtually impunctate, clypeo frontal suture sharply impressed and bi- 

 sinuate, clypeus concave, the marginal fifth sharply reflexed, coarsely 

 and very sparsely punctured, margin feebly sinuate at middle. An- 

 tenna nine-segmented. Pronotum transverse, side margins obtusely 

 angulate just before the middle, lateral margin straight near posterior 

 angle as viewed from side, viewed from above anterior and posterior 

 angles obtuse, bluntly rounded, equal ; punctures more coarse than 

 those of head, sparsely and irregularly placed. Scutellum with base 

 longer than a side, sides evenly curved, with a fev^ scattered punctures. 

 Elytra with sutural margin broadly tumid and each with a single, 

 faintly indicated discal costa, punctures less coarse but more densely 

 placed than on pronotum, epipleura very narrow, terminating just 

 before extreme apex. Metasternum finely and densely punctured on 

 median area, coarsely and more sparsely punctured laterally, clothed 

 with rather short erect hairs. Sternites, especially first and second, 

 with short, fine bristlelike setae on median portion. 



Male. — Antennal club one-fourth longer than second to sixth seg- 

 ments combined, fourth segment much longer than third. Sixth 

 sternite with a median longitudinal depression, its free margin trans- 

 verse. Pygidium strongly and evenly convex, sparsely and moderately 

 coarsely punctured and sparsely hairy, the extreme apical margin 

 sharply reflexed and produced at middle. Anterior tibia bidentate. 

 Second segment of anterior tarsus narrow with parallel sides, about 

 four times as long as broad. Aedeagus, figure 2. 



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

 combined. Sixth sternite without depression, its free margin moder- 

 ately strongly produced at middle. Pygidium very sparsely punctured, 

 with a deep, nearly hemispherical depression at middle, which is 

 connected with the basal margin by a deep groove, half as wide as the
