This species is closely allied to T. latiis, from which 

 it may be distinguished by the form of the lamellae, the 

 markino's on the abdomen, &c. 



Colour very dark dull-brown, without any gloss.

 as they occur below.

 long blades on edge, near together anteriorly ; upper 

 edge loith a blunt point or tooth at the anterior end 

 bearing the lamellar hair ; posterior to this the outline 

 is. concave, hut rises to a large sharp point or tooth 

 about the middle of the lamella, which is here broader 

 than elsewhere. Behind this point the outline is again 

 concave, but less regularly, and it finishes posteriorly 

 with a rounded convex shoulder just beyond the pseudo- 

 stigma. The lamellae are lighter in colour than the 

 rest of the cephalothorax : they are clearly reticulated. 

 No true cusps. Lamellar hairs setiform, scarcely curved.
