Gibson's reference of this species to bipunctulata Woodw. must 

 have been an over sight as that species was founded on the big, 

 broad, green female' of melanota and was so described. The 

 writer has examined the Woodworth material (he made no 

 types) in the Illinois Collection and found bipunctulata Woodw. 

 and 7iigra Woodw. to be the sexes of the species here listed as 

 melanota Spgb. and very distinct from the species described 

 above. Gibson's material was apparently all from Georgia and 

 Florida and the only excuse for the wide range given was prob- 

 ably the supposed Illinois record of Woodworth. 



NOTES ON OTHER SPECIES OF GYPONA. 



In working over the Mexican species in the course of this 

 study Gypona atitlana Fowl, and abjecta Fowl, appear to be 

 synonyms of mystica Spangb., a species described from Mexico 

 but which Fowler did not recognize. 



The writer has in his collection four South American species 

 that resemble melanota in their color variations. Gypona glauca 

 Fab. the type of the genus possesses males varying all the way 

 from the color of the females to shining black. Some of the 

 intermediate forms are highly ornamented with variable pat- 

 terns of alternate yellow and black. Gypona vulnerata Walk, 

 viridescens Walk, and obsesa Spangb. are variations of one 

 species while postica Walk, appeiars to be the extremely dark 

 form of the male. Gypona thoracica Fab., one of the largest 

 species of the group, varies from brilliant green and smoky 

 in the female through, all changes and variations of bright red 

 and shining black in the male.
