with a number of ill-defined dark blotches. Eyes umber, irregularly 

 divided into two shades; antennae mars-brown. Wings with the disk 

 yellow. 



Brown Phase. — Similar to the green phase except that the green of

 much marked with clove-brown on the head, pronotum and pleura, 

 and usually with a more or less distinct paler decussate pattern on 

 the dorsum of the pronotum, the lateral lobes of the pronotum more

Considerably over a hundred specimens of this species have been 

 examined by us in the past few years and the species shares the charac- 

 ters of Chortophaga and Encoptolophus to such an extent that the above 

 synonym can be explained on that ground. It appears that the 

 species replaces C. viridifasciata in at least the extreme southeastern 

 part of the country ranging as far as known from Thomasville and 

 Waynesville, Ga., south to Apalachicola, Miami, Chokoloskee and 

 Key West. Its range probably meets that of C. viridifasciata in south- 

 central Georgia as we have seen the latter from Marshallville in that 

 region. No doubt the references to C. viridifasciata from the region 

 frequented by the new form will on the examination of the material 

 prove to belong to australior. The species is known to us from the 

 following material : 



St. Simon's Island, Ga. September 9, 1909. Six males, seven 

 females. (Coll. State of Georgia.) 



Brunswick, Ga. April 6. Two females. (Coll. State of Georgia.) 



Waynesville, Ga. Five males, two females. (Coll. State of Georgia.) 



Thomasville, Ga. Ninety-two specimens (Hebard and Rehn). 

 (A. N. S. P. and Hebard Coll.)

 four females. (Coll. State of Georgia.) 



Apalachicola, Fla, July 21-23, 1909. (J. C. Bradley.) One
