Food plant: Rhynchosia tomentosa (L.) H. and A. Dr. Braun 

 (in litt.) gives the following notes on the mine and early stages: 

 "Mine starts at midrib and extends outward toward margin; lateral 

 vein usually formmg boundary of lower side; upper side margin more 

 irregular. Frass ejected at beginning of mine at midrib, collecting 

 in a mass. Parenchyma all consmned. Larva apparently makes 

 several mines as a large larva may be found in a very small mine. 

 Parenchyma consumed over the whole mine. Many deserted mines, 

 perhaps earlier mines large as well as small, often several on one leaf. 

 Larva pale yellow, abdominal and thoracic legs present. Cocoon 

 yellowish or whitish, tapermg to a fme point at one end, blunt at the 

 other end, convex and fuzzy." 



Holotype: cf, Chickasaw Forest, near Henderson, Chester Co., 

 Tenn., Braun 1649, emerged July 30, 1938, A. F. Braun (RWH slide 

 1039), collection of Annette F. Braun. 



Para types: same locality as holotype, 6 cT, 9 9, emerged July 28- 

 Aug. 2, 1938 (RWH slides 1038, 1040, 1041; RWH wmg slide 24), 

 AFB, USNM. 



The male of A. rhynchosiae may be separated from that of A. 

 extensa by the bifid apex of the uncus. The female may be separated 

 from that of species "a" by the submedial striae on the seventh 

 sternum.

Maculation: as in A. juvantis. Male genitalia: as in figure 36

 slide 1037) ; ostium bursae on projecting plate, two sclerotized plates 

 lying above and posteriorly of ostium bursae; heavily sclerotized line 

 running anterolaterally from plates behind ostium bursae to costal 

 margin of seventh sternum.
