 finely punctured, apical margin of segments 1 — 5 narrowly white: ventral 

 scopa fulvous-yellow. Length .60 inch. 



Hah. — Georgia, (Mr. Jas. Ridings). One specimen. A very dis-

 interrupted; sixth segment immaculate, densely clothed with pale sericeous 

 pubescence; ventral scopa yellowish. Length .46 inch.

 at tips, neuration as in maculifrons ; abdomen minutely punctured, shining, 

 a yellow band on segments 1 — 6, interrupted on middle of first segment and
