moderate. Female. — Abdomen larger than in male. Genital segment long, 

 almost as long as rest of abdomen ; both plates about equal in length and 

 quite acute ; genital pore long, about one-fifth as long as dorsal plate. Pubes- 

 cence moderate. 



Redescribed from one male .•md three females collected at Crescent City, 

 Florida, and loaned from the National Museum by the kindness of Dr. L. O. 

 Howard.* 



The original description was based on specimens taken at Jacksonville, 

 Florida. For the brief and inadequate description as given at that time, see 

 Canad. Entom. Vol. XIII, No. 10, page 224. The close resemblance in many 

 respects to A. arbolensis is very marked; this resemblance was noted as a 

 possibilitv in the preliminary synopsis, although no specimens were then avail- 

 able for comparison.
