230 NORTH AMERICAN TRYPETINA. 



C. T. Integra n. sp. % J . (Tab. XI, f. 23.) 



Long, corp. 0.41, long, terebrae 0.36—0.37; long. al. 0.42. 



The abdomen of this species is longer and narrower than in the other 

 species. The picture of the wings is paler and yellower than that of 

 Trypeta parallela, but otherwise resembles it more than any other, as in 

 both, the first hyaline band is not divided in three contiguous spots. 

 However, in the present species this band becomes narrower towards the 

 costa and stops before reaching it, neither of which is the case in T. par- 

 allela. Moreover, its wings are much narrower and less obtusely rounded 

 at the tip ; likewise they show no trace of the wavy course of the second 

 longitudinal vein and of the curvature of the third, which is so well 

 marked in T. parallela. The ovipositor is remarkably long in comparison 

 to the size of the body, longer than in all the other species described here. 

 The design of the picture might give rise to the supposition that T. Integra 

 and T. obliqua Alacq. are identical. The much smaller size of T. obliqua 

 Macq. and the much shorter ovipositor, however, render this impossible. 

 From T. consobrina and pseudopurallela this species is sufficiently distin- 

 guished by the different shape of the first hyaline band of the wings.

Abdomen short. The venation shows more analogy to that of T. par- 

 allela than to any other species mentioned here, as the third longitudinal 

 vein is somewhat curved beyond the small crossvein ; the second longi- 

 tudinal likewise shows a vestige of a weak undulation (which is not 

 rendered in the figure). The outline of the wings likewise resembles that 

 of T. parallela especially in the obtuse rounding of the apex; but the 

 wings are narrower in comparison to their length. The picture of the 

 wings is considerably paler than in T. parallela, and resembles in outline 

 that of T. pseudoparallela, so that the males of both species may easily be 

 taken for each other, unless attention is paid to the difference in the course 

 of the third vein. The females of both are very easily distinguished, as 

 the ovipositor of T. consobrina is considerably longer than that of T. 

 psea dopara I tela .

The wings resemble those of T. parallela in outline very much, differ, 

 however, in the fact that the second and third longitudinal veins do not 

 show the peculiar course which they have in T. parallela. The picture 

 of the wings is but little paler than in T. parallela, but differs from it 

 considerably in the breaking up of the first hyaline band into three con-
