to the posterior border, which it joins in the neighborhood of the 

 tip of the fourth longitudinal vein ; 3. A large triangular spot of 

 the posterior border, which occupies a great portion of the second 

 posterior cell, and with its tip reaches beyond the fourth longi- 

 tudinal vein. The stigma is long and rather dark brownish. 

 Transverse veins straight and steep ; the fourth longitudinal vein 

 is distinctly curved forwards at its end, as in Tryp. parallela Wied.; 

 the posterior angle of the anal cell is drawn out into a large point.

This very distinct species has in the picture of the wings a 

 great resemblance with the European Tryp. alternata Pall. Yel- 

 low. Front of middling breadth ; frontal bristles black, rather 

 stout. Face slightly receding, with rather deep furrows for the 

 reception of the antenna?. Antennae yellow, reaching only a little 

 beyond the middle of the face ; the bristle bare and very thin. 

 Opening of the mouth large, but not widened ; border of the mouth 

 rather sharp, but not projecting. Proboscis small ; palpi rather 

 broad. On the upper side of the thorax there is a pale yellow 

 (almost ivory color in the dry specimen) stripe running from the 

 shoulder to the base of the wing, and a second above the base of 

 the wing running from the suture as far as the posterior border of 

 the thorax. Another stripe of the same color runs from the middle 

 of the posterior border to beyond the middle-of the thorax, where 

 it is gradually pointed and obliterated; the stripe lying above the 

 base of the wing is interiorly edged with black in the described 

 specimen. Hairs of the thorax short, pale yellowish ; bristles 

 black. Scutellum of the color of the pale stripes of the thorax 

 and a black spot on each side of the base of the lateral border ; it 

 has four bristles. Pleura? with a pale yellow longitudinal stripe in 

 its middle and two black little spots above it. Abdomen yellow,
