Like T.filipes, but the disk of the chest is pale brown, and the 

 stripes on it are broader and more remote from each other : a broad 

 brown stripe along the back of the abdomen and a stripe on each 

 side are interrupted by the pale hind borders of the segments : legs 

 shorter than those of T.filipes : the space along the fore borders of 

 the wings is not so dark as in T.filipes, and the brown space beyond 

 it is more distinct than in that species and than in T. duplex ; 

 the fork of the third longitudinal vein is clouded, a character which 

 also distinguishes this from the two preceding species. Fern. — 

 Stripes on the abdomen narrow, interrupted and indistinct. Length 

 of the body 12 lines ; of the wings 22 lines.
