DESCRIPTION OF THE SPECIES. 325 



color; the second ray also runs obliquely to the anterior margin, 

 which it reaches before the middle of the distance between the 

 ends of the second and third longitudinal veins ; the third and 

 fourth rays run towards the apex and end upon the ends of the 

 third and fourth veins ; among the five rays running towards the 

 posterior margin, the first two cross, as usual, the second poste- 

 rior cell, and the third follows the posterior crossvein ; the fourth 

 originates but little beyond the posterior crossvein, exactly at the 

 place where the spot incloses a large drop, placed on the anterior 

 side of the fourth vein; it runs almost parallel to the preceding 

 ray as far as the posterior margin ; the last ray finally originates 

 at the posterior end of the small crossvein, and runs in a very 

 oblique direction, diverging from that of the preceding ray, towards 

 the margin, in the vicinity of which the intensity of its coloring 

 is diminished ; the drops, through the coalescence of which the 

 hyaline intervals between the last three rays are formed, are 

 indicated by the irregular outlines of the last two rays ; besides 

 the drop already mentioned, which is situated on the anterior 

 side of the fourth vein, the black spot contains a second drop 

 immediately beyond the end of the second vein. 



Hab. Cuba (Grundlach). 



Observation 1. — T. polyclona is a typical Urellia, and belongs, 

 as well as T. abstersa, to the division with four bristles on the 

 scutellum. 



Observation 2. — One would almost be tempted to recognize in 

 this species the T. mevarna Walker, List, etc., IY, p. 1023, from 

 Florida, which is an Urellia. But a positive identification is 

 prevented by the circumstance that Walker mentions the feet as 

 having black pile, which is not at all the case in my species.
