Callidryas eubule in Missouri. 



By R. R. ROWLEY, Curryville, Mo. 



My acquaintance with Callidryas eubule began in the Summer 

 of 1 88 1. About the middle of August numbers of this splendid 

 insect flitted about the streets of Louisiana, Mo., and I succeeded 

 in taking a fine female on garden flowers. As I had never met 

 the species before, and as all the specimens observed seemed to 

 be moving in the same direction, as well as because of the sudden 

 appearance and disappearance of so great a number of strange 

 insects, the impression was left in my mind that they were in- 

 habitants of another clime and were migrating. 



A close watch through the Summers of 1882, 1883 and 1884, 

 failed to discover a single specimen, and I had about abandoned 

 all hope of adding to my meagre knowledge of this golden winged 

 fairy, when returning from a day's tramp in the woods and fields, 

 about the middle of the afternoon on the iyth of October, 1885, 

 a fine male eubule sailed quickly across my path and settled for a 

 moment on a tall Autumn flower just over the fence, almost be- 

 yond my reach. I collected myself quickly from the astonish- 

 ment into which its sudden appearance' had thrown me, and with 

 the full length of my long net-pole, carefully and tenderly swept 

 in the treasure. It was a bright, new specimen, and had doubt- 

 less flitted out into the sunshine for the first time that pleasant 

 October day, as not a scale had been disturbed on its pretty wings. 

 I had added a new and interesting chapter to the few facts gath- 

 ered four years before,' and had completely reversed my first im- 

 pressions, being now satisfied that eubule dwelt here among us. 



Through several succeeding Summers I made frequent trips to 

 a bunch of Cassia marilandica* four miles away, but without find- 

 ing an egg or a larva (I had found this clump of Cassia in chasing 

 Terias nicippe}, having learned trom some entomological source 

 that the larva of eubule feeds on Senna. Though I saw occasional 

 imagos high on the wing, I learned nothing concerning its pre- 

 paratory stages till the mid-summer of 1888. In that year Terias 

 lisa was very abundant, and I had observed the females of that 

 species depositing eggs on Cassia cham&crista, a very abundant 

 plant along the railroad and in adjoining fields near Curryville. 

 In searching for the larvae of this latter species, on the 4th of
