TLATE V. 



All the figures on this plate are original, and represent American insects. They were drawn on stone by 

 L. Tronvelot. 



Fig. 1. Mylacris bretonense (Scudd.), p. 41. Magn. r ; ; drawn by S. IT. Scudder. 



Fig. 2. Lithomylacris angustum Scudd., p. 48. Magn. f- ; drawn by J. II. Emerton.

Fig. 9. Necymylacris hems Scudd., p. 54. Magn. 'f ; drawn by J. II. Emerton. The first (inferior) 

 offshoot, of the first scapular branch should be forked near the tip, or directly opposite the extremity of the 

 first branch itself.

Fig. 11. Mylacris JBeeri (Scudd.), p. 43. .Magn.','; drawn by S. II. Scudder. The uppermost fork of 

 the apical branch of the internomedian vein is not sufficiently longitudinal. 



Fig. 12. Necymylacris lacoanum Scudd., p. 53. Magn. \ ; drawn by J. II. Emerton. 



Fig. 13. Mylacris pennsyloanicum Scudd.. p. 44. Magn. {; drawn by J. IT. Emerton. See note to next 

 figure. 



Fig. 14. Mylacrispt misylvanicum Scudd., p. 44. Magn. ■; ; drawn by J. II. Emerton. The mediastinal 

 branch next (lie humeral lobe should have been omitted from this and the preceding figure; it docs not 

 exist. The restored outline of the wing probably extends too far outward.
