very glofly. 
The Head is larger, but its annular bafe part {maller and con-

‘the eyes, which is ftraight, conic, and tipped with a tuft of cartila- 
ginous hairs. The clypeus is only depreffed, and the jugular triangle 
wider. 
The Eyes are large and very evident, thofe of the male black, 
though in a certain light appearing greenifh; but thofe of the

The Mandibulz have large hinges, and the fuperior fheath almoft
