Long. corp. 0.37, long, terebra 0.200.21 ; long. al. 0.40. 



Arista with a short pubescence, which is longer, however, than in the fol- 

 lowing species. The pile on the body in general is somewhat longer than 

 in those species, which is especially perceptible on the abdomen of both 

 sexes and on the ovipositor. Ovipositor slender, not quite as long as the 

 thorax and the rounded abdomen of the female taken together. Wings 

 comparatively broad and very blunt and rounded at the tip; their vena- 

 tion differs from the allied species in the distinct undulation of the second 

 vein and the peculiar bend, which the last section of the, third vein shows 

 in the vicinity of the small crossvein ; two characters of which there is an 

 indication in T. consobrina only. Picture of the wings brownish-yellow, 

 in some places brown, more intense than in the following species ; the 

 uninterrupted and even course of the first hyaline space from the basis of 

 the second basal cell to the costa is especially characteristic. The picture 

 of the wings varies sometimes in the fact that both the S-shaped and the 

 V-shaped rivulet each emit, exactly npon the third longitudinal vein, a 

 little pointed projection, almost forming a narrow bridge between them ; 

 sometimes the portion of the V-shaped rivulet, cut off by the fourth vein, 

 is filled by a brownish-yellow coloring; I have observed this variety much 

 more often in female than in male specimens.

Long. corp. 0.39, long, terebrae 0.26 ; long. al. 0.410.42. 



Abdomen short. The ovipositor slender, proportionally somewhat 

 longer than in T. parallela. Wings comparatively narrower and less 

 rounded towards the end; second longitudinal vein without any trace of 

 an undulated course and the third longitudinal vein beyond the small 

 crossvein without the curvature, so characteristic in T. parallela. Picture 

 of the wings paler and more yellow than in the latter species ; the branch 

 of the V-shaped rivulet which is more distant from the tip of the wing is 

 prolonged in front beyond the third vein, without diminution of its breadth, 

 so that it coalesces with the S-shaped rivulet between the third and the 

 second vein ; the branch of the V-shaped rivulet which is nearer the apex 

 of the wing is either altogether wanting, or its pale yellowish tip only is 

 visible near the posterior margin, as it is represented on Tab. XI, f. 22. 

 The hyaline band running from the basis of the second basal cell towards 

 the costa forms (as it also does in T. consobrina and pseudoparallela'), a 

 row of three contiguous spots. Besides the different picture of the wings, 

 T. hamata differs from T. consobrina and still more from T. pseudoparallela 

 in the shape of the wings, which are comparatively narrower and a little 

 less obtusely rounded at the tip. Moreover, the ovipositor of the female 

 is a little shorter and more slender towards the tip than in T. consobrina; 

 but it is very much longer than that of T. pseudoparallela.
