Agramma biseriata sp. n.

(fig. 1)

Material examined: 1 Ψ, Laos, Vientiane prov., Ban Van Eue, 15.XII.1965, malaise trap, native coll., Rondon-Bishop.

Description: body long, narrow, glabrous, shiny; head, pronotum except tip of posterior pronotal process, sternum, abdomen, antennae dark brown, abdomen clearer; legs, hemelytra, tip of posterior pronotal process, anterior margin of collar, frontal spines yellowish. Body length, 2.33; width, 0.83.

Head longer than wide, punctate on top, flat, armed with pair of short frontal spines directed forwards; bucculae slightly produced in front of clypeus, joined in front, short and wide, with two rows of areolae, several tiny areolae in a third row; rostrum short, stout, extending beyond fore coxae, reaching middle of mesosternum; antennae stout, pilose, antennal segment measurements: I, 0.2; II, 0.17; III, 0.47; IV, 0.23.

Pronotum twice longer than wide, deeply punctate, slightly gibbose, unicarinate, the median carinae not areolate, reduced to a ridge; collar triseriate, not raised; paranota almost absent reduced to slight ridge; posterior process long, sharply angulate; sulcus narrow, open behind, laminae with small areolae, mesosternal laminae slightly sinuate; femora bent, narrowed at base, hind tarsi pilose, twice as long as wide.

Hemeytra long, narrow, slightly wider than pronotum but narrowing posteriorly; costal area biseriate throughout length, areolae larger in posterior half; subcostal area as wide as costal area, triseriate, areolae round, smaller than in costal area; discoidal area longer than half length of hemelytra, narrow, four areolae wide at widest part, areolae of same size as in subcostal area; sutural area four to five areolae as wide at widest part, areolae of same size as in costal area.

Etymology: The name refers to the entirely biseriate costal area.

Comments: This species differs from the others by its wide and biseriate costal area. Agramma amplicostatum Rodrigues , danielssoni Péricart, singulum (Drake), and yunnanum Jing all have a costal area partly biseriate, and are narrower than this new species.
