The present species begins a group of very closely allied species, very mach resembling one another. I have notliiiij^ to add to uiy above-quoted description of T. sui<pensa; 1 will only notice that the absence of pale yellow stripes on the thorax and of a pale yellow coloring of the scutellum cannot lw considered as absolutely distinctive of this species, as these marks often disappear in other species in the process of drying. The readiest distinctive mark between T. « and the very simi- lar, but larger T. fraterculua is, that in the former, the second basal cell and the root of the discal cell have a yellowish color, while in the latter they are hyaline. I regret to have to notice here, that the engraver, in figuring T. sui<pcnxa, has committed an error in drawing the curvature of the tip of the fourth vein; tliis curvature is exactly similar to that in T. fraterculus, that is, run- ning forward; and although this curved tip in T. suapensa is a little shorter, the difference is not at all such as the figure would lead one to suppose. The second basal cell and the basis of the dis- cal cell should be somewhat paler in the figure, as they are not brown, but only yellow. Hab. Cuba (Poey). 4. T. fraterculus Wied. % . (Tab.
