do. The head excavate between the eyes; the sides of the front thickened and slightly dilated, rounded 
externally ; the mandibles each with a very long, compressed, rather stout horn curving backwards over 
the head, the horns contiguous at their apex. 
Length 3-33 millim. (¢ 92.) 
Hab. Mexico, Tehuantepec (Hége, 3 ), Temax in North Yucatan (Gaumer, ¢ ). 
Three examples. Allied to E. mavillosus, but differing from it in the much larger 
and more coarsely faceted eyes in both sexes, the more transverse penultimate joints of 
the antenne, the more transverse thorax, the sides of which are more rounded in front, 
and in the form of the mandibular horns in the male sex. These horns, instead of 
curving inwards as in the same sex of E. masillosus and E. analis, curve backwards 
over the head and meet at the apex; they are also longer, stouter, and compressed. 
The head in the male has the sides of the front less dilated than in the same sex 
of EL. maxillosus.
