NEW PHYTOPHAGOUS COLEOPTERA 189 



Head very closely punctured, especially near the sides; an- 

 tennae nearly half the length of the body , the lower joints 

 obscure metallic green, the rest black. Thorax not longer than 

 broad, slightly constricted near the base, the anterior angles 

 rounded and swollen , surface with an obsolete transverse groove 

 in front of the anterior and posterior margin , rather closely 

 and finely punctured. Elytra much narrowed towards the apex, 

 very shallowy transversely depressed below the base, the shoul- 

 ders very prominent and deeply longitudinally grooved wi- 

 thin, surface strongly geminate punctate-striate , the interstices 

 also everywhere but more finely punctured and transversely 

 wrinkled , the suture very narrowly and a more or less distinct 

 spot at the sides of the elytra metallic blue or green. First ab- 

 dominal segment and the sides of the following ones , covered 

 with fulvous pubescence. 



Timor; Flores (M. Lansberge). 



This species cannot be confounded with any others described 

 by Lacordaire or other authors on account of the closely punc- 

 tured thorax and the strong punctuation of the elytra, which 

 is visible to the apex even with the naked eye. A single fe- 

 male specimen from Timor differs from the others in its me- 

 tallic green colour, and in having the suture and the elytral 

 spot, purplish. The species seems closely allied to S. Pfeifferi 

 Baly , from which it differs in the much shorter posterior fe- 

 mora of the male and in the position of the second tooth which 

 is not placed as in the latter species. The apex of the posterior 

 tibiae in .S. puncticollis is also of different structure and not 

 mucronate. 



2. Lema, dimidia^ta,, n. sp. 



Obscure fulvous; antennae, legs and the posterior part of the 

 elytra, testaceous. Thorax finely punctured. Elytra strongly 

 punctate-striate , the interstices finely punctured in a single row. 



Length 4 ^o li'^es. 



Head impunctate, with a very short central fovea; antennae
