This species is very similar to E. cniciata, described above ; 

 the two may be separated thus : 



Mesosternum entirely black ; mesopleurse black with a 

 large curved yellow mark below the tubercles and a 

 smaller, triangular one at the apex below ; the mark 

 on first abdominal segment not much longer than it 

 is wide at the apex, narrowed at the base, that on 

 the second triangular, as long as the widtli at the 

 apex, the lines on the thu-d and fourth wide, not 

 curved, continuous lineatiscutis. 



Mesosternum black, except for a triangular lateral spot ; 

 mesopleurpe yellow, with an oblique black mark at 

 the base ; the mark on first abdominal segment long, 

 narrow, on the second narrow, transverse, the lines 

 on the third and fourth narrow, not continuous . . cruciata. 



The legs are more largely suffused with rufous than in 

 cruciata, the four hind tibiae much darker coloured, the hind 

 coxse black, yellow above, the line down the centre of 

 scutellum is narrower than the apical which curves round the 

 apex, the black band on base of metanotum occupies the 

 basal fourth and is of equal width, the curved black apical 

 mark is wider at the apex than it is long, the metapleuriB
