 of iitriae except adjoining the suture, and the punctures are

Specimens of this are contained in the British Museum and 

 and in the Hope Department at Oxford. It differs from all 

 the other species known to me by the structure of the head, 

 of which the posterior lobes, instenl of b^ing, as usual, more 

 or less kidney-shaped, have a circular outline interrupted only 

 at the sides of the head, where they are rather sharply pro- 

 duced backwards. The curved channel above the eyes on 

 each side is also a very distinctive character.

Loew described the female; this is probably the male. 

 The dividing nerve, which forms three submarginal cells by 

 joining the second longitudinal and the anterior branch of 

 the third longitudinal vein, is only present on one wing. 

 The dark spots on the hind part of the wing in Loew's 

 description are here rather reduced to dark shading of all 

 the cross-veins, with the exception of the one spot in the 

 apex of the first posterior cell and a faint one on the apex of
