Dunedin and Cape Sable, Fla., Dec. 21 Feb. 23 (W.8.B.) 

 Everglade and Useppa Island, Fla. April (Davis.) My single 

 Duuedin female was beaten from mangrove overhanging the water 

 on the eastern or bay side of Hog Island, and was at once recog- 

 nized as different from sal tutor by the less pubescent surface and 

 the broad shining black stripe of lateral lobes. It is a West In- 

 dian species taken in this country only in southern Florida, hav- 

 ing been recorded, principally under the name of 0. sanlci/i 

 (Guerin), a synonym, from several places south of Puuta Gorda 

 and Miami, but not heretofore north of the former place. On Key 

 Largo it was found by R. & H. (1912) "in the twilight of the heavy 

 jungle growth by vigorously beating the foliage of the lower limbs 

 of the trees and the tangled grape and other vines." About 

 Miami in March Hebard (1915b) found small colonies in shrub- 

 bery and trees about hotels and also several beneath bark in 

 BrickelPs Hammock. Of its note he says : 



"The song of this insect was, next to that of Cyrtoxiplia onnd- 

 laclti, the most frequent sound heard on warm evenings. The note 

 is resonant, l)aaaaa, repeated incessantly at irregular intervals of 

 a few seconds. When singing, the males were found perched upon 

 the leaves of heavy bushes with tegmina raised high above their 

 backs ; considerable difficulty was experienced in locating indi- 

 vidual singers."

 subequal in length, the fifth club-shaped, concave within ; an-
