Gorham (loc. cit. p. 297) states that S. lineola is perhaps 

 not quite satisfactorily distinguished from S. lineata ; there 

 is, in fact, no difierence between them, the specimens 

 of the latter (from Cahabon) labelled by him as types are 

 females and those of S. lineola (from Chiacam) are males. 

 The Chiriqui examples mentioned, however, in each case, 

 belong to a different species, S. bugabensis, Pic. The flavo- 

 testaceous coloration of the elytra often extends to beyond 

 the middle, leaving the suture and apex nigro-piceous, 

 a long series {(^ $) captured by Hoge and H. H. Smith at 

 Teapa being thus coloured. The author's remarks on the 

 typical male of S. lineata apply to the Chiriqui specimens 

 added in the " Supplement " (loc, cit. p. 297) = S. buga- 

 bensis, Pic.
