In eighteen males from Wister only five show any exten- 

 sion of color on the hind wings distal to the nodus, and only 

 one of these has the color carried across in a mass of color 

 occupying approximately the wing breadth ; in the others the 

 nodus is attained by a narrow prolongation of color along 

 the anterior edge of the wing. All these eighteen show the 

 body colors of titia. Ten of the eighteen have the brown 

 area conspicuous beyond the red in the front wing, though, 

 as explained before, it exists in all and becomes conspicuous 

 or evident with the extension of brown distally beginning a 

 few cells beyond the quadrangle where the pink veins cease. 

 Of these eighteen males, five, as stated, have the brown area 

 of hind wing reaching the nodus, and one, as described, has 

 the brown area separated from the nodus by about 3.5 mm.; 

 the others vary in this particular from about I 3 mm. The 

 brown areas on the wing apices vary but little, the darkest 

 wings apparently having the largest spots, but these differences 

 being within narrow limits. Nothing approaching the condi- 

 tion shown in Calvert's fig. 7 and following, plate 3, Biol. 

 Centr. Am. Neur. is represented. The largest spot begins 

 slightly proximal to the stigma, others begin about the level 

 of the promixal end, while the majority are still more re- 

 duced. Variations in the stigma are conspicuous, but mean- 

 ingless, so far as I can tell. 



In addition to the above mentioned material seven males 

 from the Cumberland River, near Nashville, two males from 

 the Clinch River, Tennessee, three males from Brookville, 

 Indiana, and three males from Ohio Pyle, Pennsylvania, have 

 been studied. In these the dark color of the hind wings in 

 its posterior portion terminates at the distal end of the quad- 

 rangle ; in its anterior portion it terminates at the same level 

 in five males from Tennessee and two from Brookville, Indi- 

 ana ; in four males from Tennessee, one male from Brookville, 

 Indiana, and three males from Ohio Pyle, Pennsylvania, there 

 is a more or less distinct distal prolongation of color along 

 the anterior edge of the wing toward the nodus. 



A comparison of females from Texas and Tennessee fails 

 to show any noteworthy differences.
