A single very obscure and fragmentary specimen, and its still more 

 obscure reverse, are the sole representatives of this species ; they exhibit a 

 crushed and confused mass of head, thorax, legs, and antennae, and the larger 

 part of a single front wing, apparently of a male. Thewing is faintly infumated, 

 especially beyond the stigma, and the stigma itself is only a little deeper in 

 tint ; the wing is also covered very sparsely with excessively delicate and 

 very short microscopic hairs. The cubital vein forks beyond the discoidal 

 cell by only one-third the width of the latter, and both the veins run to the 

 tip of the wing, although very faintly. This cell is shaped exactly as in A. 

 berendti Mayr, found in amber, and is distant from the scapular vein by 

 only half its width ; the costal margin of the wing is more convex beyond 

 the stigma than in the amber species mentioned. 



The base of the wing is lost, but its probable length is 7""", and its 

 greatest breadth is 2.3™" ; length of stigma, 0.8""°.

A species of this family was found at Green River, but a specific name 

 is withheld in the hope of finding better material on which to base it. The 

 head is rather small, circular ; the thorax very regularly ovate and nearly 

 twice as long as broad ; the peduncle small and composed of two adjoining
