-50 Mr. J. S. Baly's descriptions of 



some specimens the puncturing is rather closer ; clypeus 

 rather longer than broad, sides converging from the front 

 towards- the apex, curved, apical margin usually obsolete, 

 when present only visible on either side, transverse ; an- 

 tennse moderately robust, five upper joints slightly 

 thickened, third joint longer than the fourth, fourth and 

 fifth equal. Thorax about one-third broader than long, 

 sides rounded and converging in front; upper surface 

 remotely and very finely punctured ; the puncturing varies 

 in density, being in some specimens nearly obsolete ; 

 interspaces impressed with very minute punctures, visible 

 only under a deep lens. Scutellum trigonate-ovate. 

 Elytra oblong, slightly attenuated towards the apex in 

 the $ , broader than the thorax ; above convex, the humeral 

 callus prominent ; surface finely but not very closely punc- 

 tured. Legs robust. 



This species, which, like E. ignitus, is very variable 

 in colour, is almost equally as common as that insect ; it is 

 found over a large extent of the South American Con- 

 tinent, but its metropolis appears to be Cayenne and the 

 Amazon region. 



It is smoother and more shining, and as a rule less 

 strongly punctured than E. ignitus ; the $ is to be known 

 by the longer telum and by the difference in form of the 

 abdominal fovea. In the present insect the latter is pro- 

 duced to the apical margin of the segment ; both sexes are 

 to be at once distinguished by the much less distinct emar- 

 gination of the hinder border of the prosternum.
