sete on the distal segments: segments 1 and 2 incrassate, 3 as long as 2, 4 hardly shorter, 5-8 
gradually decreasing in length, club loose; 9 triangular, a little longer than broad; 10 broader than long, 
semicircular or transverse; 11 a little shorter than 9, obtusely triangular. Eye coarsely granulate, 
lateral, oblique, semiemarginate. Frons feebly convex. Prothorax evenly convex, carina antebasal, at 
sides slightly flexed forward in an even curve, sub-basal carina distinct only at sides, longitudinal basal 
carina feebly marked. Elytra truncate at base, not emarginate, shoulder-angles rounded off. Meso- 
sternal process very narrow, less than half the width of the coxa, rounded-truncate, feebly angulate 
laterally at apex. First tarsal segment about one-third the length of the tibia in 9, a little longer than 
one-third in ¢.

3 ¢. Brownish-black, the light-pubescent parts rufescent. Head and pronotum very densely punctate- 
reticulate, slightly pubescent grey, the pronotum somewhat rugulose at sides. 
Rostrum one-third broader than long. Antenna pale rufous, segments 1, 2, 9, and 10 brunnescent, 11 paler 
than the others. 
Prothorax one-third broader than long, conical from carina, the side practically straight from carina to apex, 
a mesial spot before carina and a mesial dot behind it grey or yellowish-grey. Scutellum rounded, grey 
or yellowish. Elytra convex, not depressed along suture, cylindrical from base beyond middle, then 
evenly convex-declivous, very finely rugulose-granulate, seriate-punctate, the strie feebly impressed, 
obsolescent behind; rather sparsely grey or yellowish-grey pubescent, somewhat tessellated, a transverse 
space across middle of suture black, not sharply defined laterally. Pygidium rounded, clothed with a 
mixture of grey and brown pubescence. Underside grey. Tibia brown on upperside, with a grey patch

2. Differs from Brevibarra as follows :—Rostrum slightly spatulate. Hye finely granulose. Antennal cavity 
larger, the space separating it from the buccal fissure narrower, canaliculate. Lobes of false mentum 
acute. Mandible more pointed, less robust. Antennal segment 7 subglobular ; 8 twice as long as and 
much broader than 7, triangular ; club not loose, 11 longer than 9. Elytra feebly emarginate together 
at base. Mesosternal process as broad as coxa, short, truncate, not angulate laterally. 
Type: B. corticina, sp. n. 
1. Barridia corticina, sp. n. (Tab. X. fig. 21.) 
9. Brownish-black, rufescent, sparsely pubescent grey beneath, variegated with luteous grey above. 
Rostrum and head densely rugate-reticulate. rons flat, like the rostrum, two-thirds the width of the latter. 
Upper lip pale luteous. Antenna rufous, end-segment pale luteous, 8, 9, and 10 brown, 3 a very little 
shorter than 4, much longer than 5. 
Prothorax conical, moderately convex, longitudinally rugate-plicate, somewhat reticulate at sides, an indistinct 
mesial line and some lateral dots grey, carina nearly straight, only the extreme end flexed forward. 
Scutellum grey. Elytra feebly depressed along suture, subcylindrical from base beyond middle, punctate- 
striate, stripes feebly impressed, interspaces minutely coriaceous, alternate ones slightly dotted with grey,
