 Ro', the yellowish areas, witli the exception of the stigma, 

 are inconspicuous, arranged as follows: in the extreme anal 

 angle of the wing; along vein Cu and its two forks, occuring 

 as narrow påle seams; similar seams along m and the adjoin-

 brown. Venation (Figure): Sc2 at the tip of )S'c7 and slightly 

 longer than Sci alone, the latter ending just before the fork 

 of R2+3', Rs moderately elongated, slightly spurred at the 

 origin; cell R2 considerably longer than its petiole; a spur 

 at the bend of vein R5, jutting into cell R; m long, arcuate, 

 longer than the deflection Mz', m-cu obliterated by the short 

 fusion of Cui on 31 3+4; no supernumerary cross- veins in any 

 of the cells as in T. pictus and T. patagonicus. 



Abdominal tergites bright orange-yellow with a large 

 black basal and similar lateral blotches, the caudal margins 

 of the segments more obscure; hypopygium dark brown; 

 sternites more uniformly brownish yellow, the caudal por-

 ninth segment transversely rectangular, the caudal margin 

 broadly concave and fringed with short black hairs; a single
