448 On Two new Speciesi of Tenehrionid Coleoptera. 



LYII. — On Tico new Species of Tenehrionid 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 

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

 The two species of Tenebrionidte described below were ob- 

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

 China, during the same voyage. 



Specimens of Leichenuni serieMspidum^ Mars., hitherto 

 known only from Japan, were also captured at the same 

 locality. 



Teachtscelis, Latr. 

 TracTiyscelis chinensis, sp. n. 



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

 the tibia, the femora beneath, and the ventral segments, 

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

 cilias sparse. Head and prothorax impunctate, 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 stride faint but distinct, the others sharply 

 defined, the marginal stria deep and impunctate, the outer 

 interstices perfectly flat, the inner ones feebly convex; 

 beneath sparsely punctured, the middle of the metasternum 

 and the propleurje almost smooth ; metasternum convex in 

 front, depressed in the middle behind, deeply canaliculate. 



Length 2j-3, breadth 1^-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 stride are more distinct and the 

 inner ones deeper, the inner interstices slightly convex ; the 

 tibise 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. px^ll^ns^ Champ., from Ceylon, and T. sabuleti, Lewis, 

 from Japan, are less closely allied forms. 



Ammophthoeus, Lacord. 

 AmmopJitkorus asperatus^ sp. n. 



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

 sometimes reddish brown ; the antenuse and legs ferruginous,
