protruded for a length fully equal to one-half that of the abdomen or 

 a little more. Wings with median cross-band somewhat convex on 

 its apical margin, tlie subapical hyaline area reaching nearly to either 

 margin of wing and about one-fourth narrower than the apical area 

 of dark colored cilia; postmarginal vein about as long as the stigmal, 

 unusually thickened proximad and completely obliterating the space 

 between its own base and that of the stigmal vein, so that without 

 careful examination the marginal vein appears to be fully thrice as 

 long as thick, or much longer than it actually is, stigmal vein very 

 slender but becoming somewhat enlarged at apex. Sculpture about 

 as in II. cocTcereUi except that the pin punctures of the head are 

 larger and deeper, the reticulations on the first tergite of abdomen 

 a little coarser than in cocJcerelli, but much finer than in jlaminius, 

 being longitudinally lengthened on the sides, transversely lengthened 

 toward the base, and becoming no larger and mostly pentagonal at 

 the middle of the posterior margin, the extreme base of the tergite 

 remaining smooth. Length of body, (1.50 to) 1.76; length of head,
