 occulto. Prosternum postice declive, mesosternum parvum declive; ab- 

 domen processu intercoxali lateribus obliquis, apice truncato, sutuvis tertia 

 et quarta exaratis. Pedes mediocres, tibiis anticis paulo dilatatis, extus 

 subtiliter serrulatis, apice recte truncatis ; coxis mediis episternis arete

The head of the male, although armed with two long horns, is 

 quite different from that of Hoplocephala : in the latter the horns 

 are between the eyes, not in contact with their margin, and the 

 vertex and occiput are deeply excavated at the middle ; the an- 

 terior margin of the epistoma is reflexed and bidentate. In the 

 present genus the horns rise abruptly from the inner margin of 

 the eyes, and there is a large rounded excavation behind each 

 of them, the middle of the vertex and occiput being convex ; the 

 epistoma is not margined or prominent in front, although armed 

 with two small, distant, dentiform tubercles. 



407. E. ferruginea. Elongato-ovalis, convexa, ferruginea nitida, 

 capite punctulato, tborace punctato, basi vix bisinuata tenuiter mar- 

 ginata ; elytris striis profundis punctatis, interstitiis convexis parce 

 punctulatis, stria scutellari brevi. Long. *20. 



Mas capite cornubus duobus elongalis cylindricis armato, pone comua 

 utrinque valde excavato ; epistomate versus apicem denticulis duobus 

 remotis armato, dein subsinuato. 



"Remina capite mutico, fronte lunatim impresso, epistomate apice late
