eter of the winor ; the second median cell is scarcely more tlian half as large 

 as the first subcostal cell, siibquadrate, broadest below; the first subcostal 

 cell is annulate, but broadly oval, its larger diameter along the wing almost 

 twice as long as broad.

Represented by a single fore-wing in perfect preservation. It is uni- 

 formly and scarcely infumated, the anal cell decidedly fuliginous, the stigma 

 also fuliginous and centrally infuscated; as preserved on the stone the 

 veins are pale and delicately edged witli black and accompanied by a very 

 narrow and delicate infumated margin, especially in the basal and lower 

 halves of the wing-; the median vein does not reach the margin of the wing 

 next the anal excision, but bends and runs in a straight course to the outer 

 border ; the second median cell has numerous brief shoots from the nerv- 

 ures along its lower and outer margins, and one is found at the middle of 

 the upper margin of the second subcostal cell, and another below the mid- 

 dle of the vein separating the first and second subcostal cells. 



Length of wing, 6"""; breadth of the same beyond the costa, 2.1™'".

A single specimen and its reverse show a body without wings or other 

 appendaofes. The head is quadrate, broader than long, and nearly as broad 

 as the thorax. The thorax is subquadrate, either extremity rounded, about 

 half as long again as broad, the sides nearly parallel, and the surface, like 

 that of the head, minutely granulated; abdomen fusiform, very regular, in 

 tlie middle as liroad as the thorax, as long as the head and thorax tog-ether, 

 tapering apically to a point, and composed apparently of six segments.
