gin; the vena interno-media divides several times, the uppermost 

 branches forking again just inside of the border; the vena analLs does 

 not appear on the fragment. 



There are six hirger round or squarish spots; four of them form a 

 bent row a little beyond the middle of the wing, the upper three spots 

 being nearly straight and the lower one turned inward at a little more 

 than a right angle; the uppermost spot occurs in the interspace be- 

 tween the vence scapular is and exlerno-media; the others follow in suc- 

 ceeding interspaces. The two other large spots are found in the same 

 interspaces Avith the upper two of the inner row, and are situated 

 about half way between them and the border. The smaller spots 

 appear to be less regularly distributed; they are usually round, but 

 sometimes oval or elongated; there are three at equal distances from 

 cacli other in the lower outer interspace formed by the branches, of the 

 I'ena scapularis, one occurs just within and above the inner of the 

 three just mentioned, and one near the angle of the last divarication of 

 the vena scapidaris ; there are two between the forks of the upper 

 branch of the same and, in the interspace between the branches one 

 spot is found close to the mr.rgin; two larger and elongated spots 

 occur in the same interspace witli the lowest of the four large spots 

 and three equidistant round ones in the next interspace below; in 

 ' the succeeding interspace, probably about half way between the base 

 and the outer border, there is an oval spot; finally two faint ones are 

 situated upon and beneath each of the branches of the vetia externo- 

 media near the middle of the wing. 



The wing was probably a little more than three inches in length; 

 its greatest breadth measured by a line at right angles to the costal 

 border is 1.8 inch; from the apex of the wing, whei'c the upper 

 branch of the vena scapularis touches it, to the lowest point of the 

 lower outer angle 2.1 inches; from the centre of the upper, inner 

 large spot to the ou'er margin 1.05 inches; greatest breadth of an 

 interspace, .34 inches. This insect, apparently allied to the Coniop- 

 terygidce by the sim.pliclty of its neuration, ditfers from that family, not 

 only in the cross-veining, but in the mode of branching and the jiro- 

 portlon of the wing allotted to each of the veins. Dr. Ilagen has 

 shown me in this wing some resemblances to the Phryganidm, but I 

 am inclined to believe it is distinct in its family characteristics from 

 .any known type of Neuroptera. 



The second insect, for which the name of Arcliefjogryllus prisons is 

 proposed, was found by Dr. J. S. Newberry in the lowest coal beds at 

 Tallmadge, Ohio. It consists of a broken leg of a cricket and a very 

 small fragment of its wing — apparently a lower one. There are no 

 determinate characters in the wing. The leg was broken into 

 fragments from which a femur and tibia could be made out; they
