2 MERISMODERUS HAMATICORNIS. 



Rather dull , pale rufous , the antennary club almost en- 

 tirely blackish except at the base, the elytra ornated with 

 a very large black band , its upper margin obliquely direc- 

 ted towards the suture , the lower margin , which is less 

 oblique, united with the apex by a narrow black border 

 along the suture. 



Head very short and broad, strongly rounded behind 

 the eyes, the front part rather strongly depressed and the 

 vertex much inflated near the hind margin. The anten- 

 nary club slender, apparently composed of five joints, being 

 divided by four deep transverse impressions; the basal 

 pseudo-joint shorter and broader, prolonged at the inner- 

 side into a subtile spine, curved at the tip and obliquely 

 directed towards the head; joint 2 — 4 about of equal size, 

 the apical joint large, as long as two of the foregoing to- 

 gether, broadly rounded at the tip. Prothorax bipartite, 

 the front part much narrower than the head, very deeply 

 impressed in the middle, forming two large elevated arcu- 

 ate lobes ; the basal part as wide as the head , on a much 

 lower level than the forder part, with a deep impression 

 in the middle and a somewhat shallower one on each side , 

 somewhat four-lobed. Elytra entirely and rather densely 

 covered with long fulvous hairs; the shoulders broadly 

 rounded , the sides almost straight , slightly swelling out 

 just before reaching the apex, which is largely truncated. 

 The pygidium is provided with a strong, arcuate ridge, 

 parallel to the outer margin , gradually enlarged towards 

 both ends and slightly impressed. The legs slender; the 

 fordertarsi with joint 1 — 4 small, gradually decreasing, 

 the last joint very long; the intermediate and posterior 

 tarsi with the basal joint large nearly as long as the three 

 next following together, these gradually decreasing, the 

 ultimate joint very slender. 



The genus Merismoderus being composed of a single 

 species only , viz. M. Bensoni Westw. from continental 

 India, which is of extreme rarety in collections, the dis- 

 covery of a second species from Sumatra must be consi-
