TRYPETIDAE. 85 



apical black spot including two limpid drops and emitting eight rays to 

 the border of the wing. Long. corp. 0.17. Long. al. 0.16 0.17. 



One of the group of the European T. stellata Fuessl., cometa 

 Loew, gnaphatii ^Loew, etc., and very much resembling these 

 species. Head yellow ; front rather broad ; frontal bristles black- 

 ish ; the bristles of the posterior orbit whitish. Front a little 

 prominent, face slightly receding and a little excavated in the 

 middle, so that the borer of the mouth projects again. Antennae 

 rather broad, reaching down to beyond the middle of the face, with 

 the bristle having a very short, hardly visible pubescence. Open- 

 ing of the mouth very large ; proboscis and palpi short. Thorax 

 whitish-gray with a pale yellow dot at the shoulder angle, and a 

 second immediately before the base of the wing. The short hairs 

 of the upper side of the thorax are whitish, the bristles blackish ; 

 of the four bristles in its middle, the first pair is very near the 

 suture. Scutellum with only two long bristles. Abdomen whitish- 

 gray at the base, more ashy gray towards the end, with short, 

 whitish-yellow hairs, the hind border of the last segment having 

 .black bristles. Borer shining black, flat, tapering towards the 

 end, nearly as long as the three last abdominal segments taken 

 together, with black hairs. Legs dark-yellow. Wings whitish 

 hyaline before the tips, with a large radiating spot, incumbent to 

 the costal border ; this black spot includes two clear drops, one 

 of which on the costal border immediately behind the tip of the 

 second longitudinal vein, the second between the two transverse 

 veins at the anterior side of the fourth longitudinal vein. The 

 first ray runs from the anterior end of the small transverse vein to 

 the stigma, in which it vanishes ; the second is shorter and reaches 

 the costal border between the tip of the first longitudinal vein and 

 the black spot itself; the third and fourth rays run to the tip of 

 the wing, reaching it at the tips of the third and fourth longitu- 

 dinal veins ; the fifth and sixth cross the second posterior cell ; the 

 seventh includes the posterior transverse vein and reaches the pos- 

 terior border of the wing, whereas the eighth reaches only to the 

 fifth longitudinal vein. The small transverse vein lies outside of 

 the black spot ; yet in its whole neighborhood the surface of the 

 wing is brownish, and a small gray spot lies immediately before it. 

 Transverse veins approximated, perpendicular ; the small trans- 

 verse vein rather far beyond the tip of the first longitudinal vein.
