All the specimens of axilena are young with the teneral body color 

 pattern distinct, and the postnodal wing streak between C and R and 

 nodal spots are present in every specimen. In every specimen but one 

 the brown area about the metastigma is continuous with the brown area 

 anterior to it. In every case the brown stripe on the second lateral 

 suture is wider than in znbrans, and between this stripe and the dorsal 

 thoracic dark area, on the side of the thorax above, is a triangular 

 brown area which is entirely wanting in ribraus. In ribrans the post- 

 nodal wing streak is present in one female, faintly present in two 

 males and two females, and absent in nineteen males and fourteen 

 females. In every case the brown area surrounding the metastigma is 

 separated from the dark area anterior to it, and the sides of the thorax 

 above, between the humeral and second lateral sutures, are entirely pale. 



The color pattern of the thorax as well as the pale face and 

 frons thus separate vibrans certainly from axilena. 



At Fort Myers, flying about and alighting on dried vege- 

 tation in the sun along a fence separating a cemetery and 

 orange grove. This species and vibrans were not recognized 

 as distinct when captured and it is impossible now to state 

 definitely any difference in habitats. In L. A. W.'s material 

 collected at St. Petersburg, March 22, a male of vibrans and 

 a female of incesta are papered in the same envelope. His 

 other specimens of axilena were taken on March 13, three and 

 one-half miles southwest of St. Petersburg, while his twelve 

 specimens of vibrans were taken on March 22, four miles 

 southwest of town. J. H. W. collected axilena on thirteen 

 days and vibrans on ten days in Florida. On four different 

 days he took both species, on nine days he caught axilena and 

 not vibrans. and on six days vibrans but not axilena. Both 

 species certainly occurred in the same creek-enclosing wood- 

 lands at Palmdale and Enterprise, but were not found on the 

 creeks themselves. Apparently axilena frequented more open 

 spots and the edges of forests, while vibrans preferred denser 

 forest.
