Agramma bangkhensis sp. nov.

( Figs 3 , 4 )

Holotype. 1M, Bangkhen, nr. Bangkok , 2.IX.1958, J.L. Gressitt coll., BPBM .

Description. body shiny, yellowish, calli, sides of pronotum, and body beneath dark brown, head black, except margins of bucculae. Hind tarsi short and enlarged. Body length, 2.20; width, 0.82.

Head armed with two tiny frontal spines, bucculae wide, three areolae wide, closed in front; antennae long and slender, two first joints slightly stouter, antennal joints measurements. I, 0.18; II, 0.15; III, 0.52; IV, 0.23; rostral sulcus wide and wider on metasternum, largely open behind; rostrum short, slightly extending beyond prosternum.

Pronotum a little gibbose, unicarinate; median carina distinct and slightly raised on posterior process, almost indistinct on top of pronotum; collar small, two to three areolae wide, not raised; paranota absent.

Hemelytra long, a little wider than pronotum, without distinct boundary veins delimiting areas, except costal area; costal area straight, biseriate, the areolae round and large; subcostal area triseriate for male and quadriseriate for female, wider than costal area, the areolae smaller than on costal area, not distinctly delimited from discoidal area, and both sloping downwards; discoidal and sutural areas almost indistinctly differentiated, discoidal area four areolae wide at widest part, sutural area four to five areolae at widest part.

Comments. This species is close to A. sedale (Drake) but differs by the color of the pronotum which is lighter, and by the form of hemelytra without distinct delimited areas and a biseriate costal area, while the one of A. sedale is mostly uniseriate. It resembles somewhat the genus Litadea by the form of the hemelytra with indistinct areas, and short, enlarged and hairy hind tarsi. However, the hind tarsi are less enlarged, the hemelytra much narrower, and the antennae slender and not pilose as on Litadea species. In addition, Litadea is restricted to Rodrigues Island in Mascarene.

Etymology. This species is named referring to the site where it was collected.
