in eacli hind wing, but there are occasional specimens with but five. 

 Sometimes one wing has five and the other six. In the wTiter's col- 

 lection two female calliope from Louisiana have five apical areas in 

 each hind wing, and a male from Alabama has five apical areas in the 

 left hind wing and six in the right. A male from Clarke Co., Mis- 

 sissippi, has five apical areas in 'each hiiul wing. I'his specimen is 

 figured on the plate. In Entomologica Americana, Vol. IV, p. 82, 

 1888, Uhler states: "Several specimens of .1/. parvnla [calliope] 

 have been examined by myself, in which six apical areoles were 

 present in one wing and five in the opposite one." 



While in kaiisa the median and cubitus veins unite near the base 

 of the fore wing, thus placing it in the Division Melampsaltaria Dis- 

 tant, the fact that it has but five apical areas in the hind wing would 

 seem to consign it to the genus Panropsalta Coding and Froggatt. 

 In the original description of the genus the head is said to be as 

 ■' wide or a little broader than front of pronotum." It is narrower 

 than front of pronotum in kansa, and the illustration of the venation 

 and shape of the fore wing of Icnrcnsis Coding and Froggatt, the type 

 of the genus, from Australia and Tasmania, show other- differences. 

 So it has been thought best for the present to leave kansa in the genus 

 Mclampsalta. 



As the gen,us Mclampsalta is not a congested one in North Amer- 

 ica, it will do for the present to also include camcrona therein, though 

 there is the same objection as in kansa, namely the small number of 

 apical fereas in the hind wing. However, this character has here been 

 shown to be variable to some extent in the same species.

(Mentioned in this paper.) 



Hind wings with 6 apical areas; rarely there are specimens with but five. 



Females straw colored, occasionally with dark marks on the head and 

 thorax. Males usually smaller and with dark marks. Females expand 



about 3,7 mm. ; males about 35 mm calliope (Walker). 



Both sexes green, immaculate, or nearly so. 



calliope var. floridensis new variety. 

 Hind wings with 4 or 5 apical areas. 



Hind wings with 5 apical areas; body slim, of the same width across the 

 region of the tympanal openings as immediately above and below. Both 

 sexes immaculate green and of the same size ; expands about 32 mm.
