 different.

Head, pronotum, seutellum, and legs piceous ; corium and body 

 beneath very dark castaneous ; apex of seutellum and eyes reddish- 

 ochraceous ; antenniie black, second joint a little longer than the 

 third (remainder mutilated in type) ; pronotum with the lateral 

 margins distinctly reflexed, rounded anteriorly, and a little 

 concavely sinuate before the posterior angles, which are sub- 

 prominent ; before the rounded anterior lateral margins is a broad 

 sublateral rugosity which is strongly transversely striated, remainder 

 of disk somewhat faintly stxnated and moderately punctate ; 

 posterior femora in male strongly incrassated, beneath with a long 

 robust curved spine near base, and with a series of small obtuse 

 spines near apex. Other characters as in E. robustiis, but 

 E. thoracicus differs from that and other species of the genus by 

 the structure of the pronotum. 



Length 36; breadth between pi*onotal angles 17; greatest 

 abdominal breadth 20 millim.

Castaneous, cupreous, or olivaceous-brown, seutellum always dark, 

 sometimes darker than remaining surface : antennse black, extreme 

 tip of apical joint rufescent : body beneath pale castaneous, legs a 

 little darker ; body somewhat narrow and elongate. 



Length 26 to 28 : breadth between pronotal angles 12 to 13 ; 

 greatest breadth at corium 14 to 16 millim.

Stal, writing on the above species, states that in collections 

 two species are confused. One (length 24; breadth 12 millim.) is 

 distinguished by its smaller size, its somewhat more brilliant colour, 

 by having the anterior part of the pronotum and the hemelytra at 

 base olivaceous, the antennae shorter, the anterior margins of the 

 pronotum not reflexed, and the dorsum of the abdomen with a 

 large shiny brassy-green disk'. For this species he proposes the 

 name of E. tlieseus, Stal. I have not seen any species agreeing 

 with this description from our fauna. The dimensions given by 

 Stal for E. cupreus (length 29-35; breadth of hem. 14|-17| 

 inillim.) exceeds the size of the series of specimens now before me. 



E. cupreus and the two following species are distinguished by 

 more elongate structure.
