Ten specimens, quite similar, as well as I can recollect, to those mentioned by me 

 from Brazil (op. cit.). I cannot find any description which will apply to them. They 

 differ from E. fasciatus, especialiy, in the lighter coloured anteima?, in the broad 

 interruption of the sutural ashy band, and in the spots of the second abdominal 

 segment being approximated or subcontiguous anterioiiy. The femora seem somewhat 

 less incrassate. The species comes yet nearer to E. twnia, Wiedem., but seems distinct 

 from it, apart from the interruption of the sutural band, by the almost entire absence 

 of the ashy colour on the anterior part of the dorsum. The dorsum is opaque black, 

 with a pointed spot on each lateral suture. The females have a yellow or red spot on 

 each side of the third and fourth segments, usually wanting in E.fasciatus.

Eight specimens. 



The females agree in all respects with an example of the same sex from Brazil. The 

 two males are distinctly smaller (11 millim.) than the Brazilian examples of the same 

 sex which I have for comparison; one of them has the tibiae and tarsi reddish- 

 yellow.
