326 NORTH AMERICAN TRYPETINA. 



Hob. Georgia (Osten-Sacken). 



Observation. To the above-quoted description I must add, in 

 order to facilitate the distinction from the following species, that 

 the rays running towards the posterior margin are strongly 

 marked, and that the last of them ends abruptly at the fifth vein 

 (the distance is too large in the figure); that there is no trace of 

 a blackish spot near the fifth vein, but that, in the discal cell, 

 immediately beyond its middle, there is an exceedingly minute 

 gray mark. This species is a typical Urellia, of the group with 

 two bristles on the scutellum. 



61. T. actinobola n. sp. . Albido-cinerea, capite pedibusque 

 flavis, setae scutelli duse, alae totae albo-hyalinae, praeter punctum nigrum 

 venae quintae oppositum in dimidio apicali macula magna nigra ornatse, 

 guttas duas includente et radios septem integros, octavunique abbrevi- 

 atum eiriittente. 



Whitish-gray, head and feet yellow, scutellnm with two bristles ; wings 

 altogether whitish hyaline, with the exception of a punctiform dot on 

 the fifth longitudinal vein and of a large black spot upon the distal 

 half of ~the wing; the latter contains two drops and emits eight rays, 

 the last of which alone is abbreviated. Long. corp. 0.13 0.14; long, 

 al. 0.15. 



This species is so very like the preceding that the mention of 

 the differences in the picture of the wings will be sufficient for its 

 recognition. There is no trace here of the brownish coloring 

 which, in T. Solaris, surrounds the small crossvein, and likewise 

 none of the minute mark in the first basal cell, near the small 

 crossvein ; the little dot beyond the middle of the discal cell 

 which occurs in T. Solaris is likewise wanting here ; but instead 

 of these, there is, on the posterior side of the fifth vein, nearly 

 under the end of the first vein, a very well-marked punctiforra 

 blackish dot ; the large black spot on the apex is very like that 

 in T. Solaris, with the following differences : the first ray is not 

 extinguished within the stigma, but crosses it without being dis- 

 colored and reaches the margin ; the rays running towards the 

 apex and the posterior margin are very much narrower; the same 

 applies to the last ray, which, moreover, is interrupted already in 

 the discal cell, before reaching the fifth vein. 



Hab. Texas (Belfrage).
