Dunedin and Cape Sable, Fla., Dec. 31 — April 3. Taken at 

 Dunedin, Jan. 8, by scores and in all stages from beneath the 

 thin bark of a dead sprout of red bay, Persea borbonia L. ; also 

 on numerous other occasions by beating dead vines, dead oak 

 limbs, and the foliage of the scurfy Ericad, Xolisma ferruginea 

 {Walt.), Heidemann (1904a, 164) records it from Bruns- 

 wick, Ga., where it was "found April 26, in deserted galleries 

 of a small Cerambycid in dead branches of Sumac." He also 

 notes its occurrence in southern Florida, but it is not included 

 in Barber's 1914 Florida list. Aside from these two states it 

 is known from Texas, Arizona, Mexico and the West Indies. 

 Osborn mentions it as having been taken at Cincinnati, Ohio, 

 but this record may have been based on a wrong identification. 

 Of the 16 specimens at hand five, all males, are of the dark 

 form with white elytra.
