scription) 



This beautiful, golden-winged, southern species is not Hkely to be found 

 in the state except near the coast. A few years ago Prof. A. L. Quaint- 

 ance reared the species at Lake City Fla., and very kindly sent me the 

 bred specimen with its cast skin, and some nymphs in alcohol. I have 

 several times since received the nymphs from other localities in the south. 

 I have not seen the species at large. 



Nymph. Total length 27 mm; abdomen 17.3 mm; hind femur 6 mm; 

 width of head 6 mm, of abdomen 7 mm. 



The body is a trifle heavier than in the nymph of b a s a 1 i s and more 

 hairy; the median lobe of the labium is decidedly pointed in the middle 

 of its front border; lateral setae five ; mental setae eight to ten, the six 

 outer ones forming a larger series; movable hook rather stout and little 

 curved; ninth abdominal segment twice as long on the ventral as on the 

 dorsal side, twice as long above as the loth segment; dorsal hooks on 

 segments 3 or 4-8, straight, and sharp; appendages as long as the two 

 last abdominal segments, the laterals half as long as the others.

This species has not as yet been taken in the state : it is almost sure 

 to be found there eventually. It ranges from New Hampshire to Texas, 

 and is said to be common in places in Ohio. Its nymph is unknown.
