middle scries of definitely arranged cross-veins all the longitudinal veins 

 and their branches are united by cross-veins all the way to the base; these 

 an- straight and transverse except between the costal and upper radial veins, 

 \\ lii-re the wing is more or less reticulate. The wing is more or less fuligi- 

 noiis, with two small, faint, round, pale spots on the costal border on either 

 side of tin- curious arcuation of the veins.

Gravenhorst and Burmeister have both reported species of Plata as 

 found in amber, hut none were described or mentioned by Germar in 

 Uereii It's great work, neither have any been reported from the rocks. The 

 '_:< -mis Lithopsis, however, which I formerly regarded as one of the Tropi- 

 duchida, appears to belong here, the two anal veins in the clavus being dis- 

 tinctly separated throughout 1 have now another species to add to that 

 first described.
