A. xanthoptera Germar. Plate VIII, 5. 



This species is somewhat larger than siilphurea and will be 

 readily recognized by the characters given in the key. The front 

 of the vertex is truncate ; its lateral carinse do not meet but 

 are continuous with the sides of the frontal costa, which scarcely 

 approach each other, and do not meet at the apex. The color 

 varies from yellowish brown or bright reddish brown to nearly 

 black. The tegmina, especially of the female, are sprinkled with 

 dark. The disks of the wings are of a deeper yellow than in 

 siilphurea. The sub- frontal shoot is about as long as the width 

 of the band, and reaches less than half-way to the base of the 



This species occurs in similar locations to, and with siilphurea, 

 replacing it during the latter part of the season. 



Chortophaga Saussure. 

 Body rather slender, compressed, and punctate or finely 

 wrinkled. Vertex triangular, the apex truncate. Median carina 

 absent. Lateral carinae rather faint. Lateral foveolae triangular 

 and very shallow. Frontal costa rather narrow, the lower part 

 sulcate, the sides approaching each other slightly on the upper 

 part and meeting those of the vertex. Antennae rather short 

 and flattened. Disk of pronotum roof-shaped, the front obtusely 

 angled and produced forward slightly upon the occiput, the 

 posterior margin acute-angled. Median carina prominent, 

 slightly curved in profile, faintly cut a little before the middle. 

 Lateral lobes of the pronotum deeper than long. Tegmina nar- 

 row, extending beyond the abdomen. Inner wings with the 

 apical half somewhat smoky. Hind femora of medium size, sur- 

 passing the abdomen in male, usually slightly shorter than the 

 abdomen in female.

This is the only species of our CEdipodince that is dimorphic 

 in regard to color. Several forms have been described ; but,
