ed; the 3rd cubital cellule above is distinctly shorter than the 2nd. 
The 2nd abdominal segment becomes gradually wider towards 
the middle, it is not being dilated in the middle, nor narrowed at 
the apex; the last segment has a broad, smooth glabrous band 
extending from near its base to the apex and becoming gradually 
wider towards the apex. The ventral keel is slightly dilated 
at the apex. Tegule black on the inner side, the middle rufous, 
the outer edge paler. 
This is a more slenderly built species than MV. attilla; it may 
be known from it by the incised apex of the clypeus and by the 
front and vertex not being uniformly rugosely punctured. 
Discolia ocina, sp. nov. 
Black; the vertex and the upper half of the outer orbits 
pale orange; the wings uniformly dark purple-violaceous; the
