of the pine belt along the east coast. The isolation of this Austro- 

 riparian species from its congeners of this otherwise Sonoran genus is 

 similar to that of the Florida Jay {Aphelocoma cijanea) and less 

 typically to that of the Florida Burrowing Owl (Speotyto cunicularia 

 floridana), the latter, however, having West Indian relatives which 

 may have been the parent stock of the peninsular form. 



Biological Notes. — All known ' concerning the habitat of this 

 species is that it usually occurs in or near pine woods, in the under- 

 growth of which it was taken at Gainesville. The three specimens 

 from Homestead were found dead in spider webs on the railroad 

 station, to which spot they had been attracted by lights, the lo- 

 cality being surrounded by pine woods. The specimen from 

 Augusta, however, was found among grasses in a sandy scrub oak 

 area just above the fall line. 



From the material before us it is seen to occur adult as early in 

 the year as June 29 (Thomasville), August 16 being our latest 

 date. A female in the instar preceding maturity was taken by 

 Davis on April 23 (Fort Myers). 



Morphological Notes. — The number of rami of the discoidal vein 

 varies in the present species from four to six, two males having 4-4, 

 one male and three females having 4-5, one male having 5-5, one 

 female having 4-6, one female having 5-6 and one male having 

 6-6. The number of these rami has no geographic significance. 

 There is some little variation in the acuteness of the angle of the 

 caudal margin of the pronotal disk in both sexes, also in the exact 

 form of the speculum of the male, the Thomasville one having, as 

 well, a more marked sinuation of the sutural margin of the stridu- 

 lating field than in the others of that sex. The Sanford and Home- 

 stead males have the expanded marginal field of the tegmina larger 

 and more elongate than in the Thomasville male, in the two former 

 this being more than and in the latter less than a fifth of the teg- 

 minal length, while in the females from Homestead the length of 

 the expanded marginal field is contained slightly more than four 

 times in the tegminal length and in the Sanford and Gainesville 

 females slightly less than four times in the same. 



In the Thomasville male the cerci are slightly more robust than 

 in the others of that sex. The medio-longitudinal thread on the 

 pronotal disk described in the male varies in definition in the series, 

 being absent in some specimens and completely or partiall}' indi- 

 cated in others regardless of sex.
