The base of the prothorax of the present species is quite as 

 wide as the base of the elytra ; these latter are slightly \\-ider at 

 their postmedian than at their posthumeral dilatation, and their 

 l)ase projects forward conspicuously and angularly at a point be- 

 tween the fifth and sixth punctulate-strise. 



From S. strami7iea, Macl. (of which I possess a type), *S'. guttata 

 differs hiter alia in the same respects as from *S'. himaculata. I 

 may remark here that S. himaculata must be very close to 

 S. straminea, judging from the figure and description of the 

 former, which scarcely show any difference from the latter except 

 in the postmedian spot on each elytron being nearer the suture 

 and the apex of the elytra being more strongly spined. 

 S. cinnaino7nea, Mad., and auricoUis, Thorns., are near the 

 present species ; the former is insufficiently described, but has 

 the head " finely punctured " and the elytra devoid of isolated 

 spots ; the underside of the latter is entirely metallic green.

^. guttata^ sexus alter (?). Sat angusta ; sat convexa ; elytris 

 (exempli typici) basi summa (vix manifeste), sutura (hac 

 ante apicem rotundatim dilatata), linea obliqua posthumerali,

 thorace quam longiori (et postice quam antice) vix plus 

 dimidio latiori, latitudine majori vix pone medium posita, 

 lateribus sat fortiter rotundatis ; elytris basi quam pro- 

 thoracis basis sat latioribus, segmento ventrali apicali

Var. ? Elytrorum notis viridibus plus minus (nee omnino)

 neque exceptis). Long., 6J 1. ; lat., 2J 1. 



This insect occurs in the same localities as S. guttata, and bears 

 so many striking resemblances to that species that in spite of 

 serious discrepancies I cannot satisfy myself that the differences 

 are more than sexual. Each form is extremely variable — indeed, 

 I have not seen two examples of either quite identical. The ex- 

 treme of the last described form has elytra entirely testaceous 

 except the suture ; another example has the metallic colour of 

 the suture interrupted in several places and a single metallic spot 

 on either side behind the middle.
