LVII. — On Two new Species of Tenebriontd Coleoptera from 

 Namoa Island. By G. C. Champion, F.Z.S. 



In the current volume of this Magazine, pp. 49-71, 98-110, 

 an account is given of the zoological collections made at 

 Damma Island by two of the officers of H.M.S. 'Penguin.' 

 The two species of Tenebrionida? described below were ob- 

 tained by Mr. J. J. Walker at Namoa Island, South-east 

 China, during the same voyage. 



Specimens of Leichenum seriehisftidum, Mars., hitherto 

 known only from Japan, were also captured at the same 

 locality. 



Trachyscelis, Latr. 

 Trachyscelis chinensis, sp. n. 



Short ovate, ferrugineo-testaceous, shining, the apices of 

 the tibiae, the femora beneath, and the ventral segments, 

 except at the sides, more or less pitchy brown ; the marginal 

 cilia? sparse. Head and prothorax impnnctate, the latter 

 nearly three times as broad as long ; elytra widest a little 

 behind the middle, very finely punctate-striate, the sixth, 

 seventh, and eighth stria? faint but distinct, the others sharply 

 defined, the marginal stria deep and impnnctate, the outer 

 interstices perfectly flat, the inner ones feebly convex; 

 beneath sparsely punctured, the middle of the metasternum 

 and the propleura? almost smooth ; metasternum convex in 

 front, depressed in the middle behind, deeply canaliculate. 



Length 2^-3, breadth 1^— 1 § millim. 



Numerous examples. Closely allied to the Australian 

 T. Icevis, Champ.*, and differing from it as follows : — The 

 sixth to the eighth elytral stria? arc more distinct and the 

 inner ones deeper, the inner interstices slightly convex ; the 

 tibia? are infuscate at the tip ; and the under surface is more 

 sparsely punctured, the metasternum almost impunctate and 

 shining in the middle, and also more convex anteriorly. 

 T. pallens, Champ., from Ceylon, and T. sabuleti, Lewis, 

 from Japan, are less closely allied forms. 



Ammophthorus, Lacord. 

 AmmophlJiorus asperatus, sp. n. 



Oval, very convex, subopaque, black or piceous ; the elytra 

 sometimes reddish brown ; the antenna? and legs ferruginous,
