(In one specimen the 2nd and 3rd cubital nervures are 
exactly confluent on the radius, in the other they are 
separated by an exceedingly small interval—about equal 
to the thickness of the radius itself.) The quadridenticu- 
late clypeus is exactly that of epeoliformis.

This is perhaps undescribed, but I think it better not 
to give it a name, especially as I have a suspicion that it 
may be the other sex of a new Spanish % kindly com- 
municated to me by Sefior Mercet. In size and colour it 
resembles dimidiatus, but is much more strongly punctured, 
the antennae (at least beneath) are distinctly pale, and 
the collar bears two transverse oval spots of yellow which 
are conspicuous and quite similar in all three specimens.

This species, | think, must be new. In colour it seems 
very nearly, though not in every detail, to resemble 
rufus, Hdl. of which the author only knew the . But 
in structure it appears to be altogether unlike that species, 
having a distinct though small tuberculation between the 
antennae, a different form of 2nd ventral segment, and 
a perfectly normal 9 pygidial area.
