The Gray Hair-streak Butterfly (Uranotes [Theda] melinus Hbn.).— 
Among other garden insects observed by Mr. A: N. Caudell upon the 
occasion of his collecting trip in Colorado during the summer of 1901 
was the caterpillar of this pretty butterfly, feeding on the pods of 
Windsor bean, in the gar- 
den of Mr. E. J. Oslar, at 
Denver. Normally they 
live in that region on As- 
tragalus mollissimus Torr. , 
a leguminous and, it might 
be added, pestiferous plant, 
growing on prairie land and 
commonly known as ' ' loco 
weed." 
During the last four 
years this species has been 
under observation as an 
enemy of beans. In fact, 
the bean, although not perhaps a special food plant, appears to be 
attacked every year by this insect, although injuiy is not as a rule 
severe. 
In 1897 Prof. W. G. Johnson observed it on bean in Maryland (Bui. 
9, n. s., Div. Ent., p. 83). 
The next year the writer observed the larva on hog peanut (Fal- 
cata [Anqjhwarpsea] monoica) and tick trefoil (Meihomia spp.). The 
resemblance of the larva to the pods of the last-mentioned plant is 
striking. A number of other wild food plants are recorded, including 
among the legumes, bush-clover (Lespedeza). 
July 8, 1899, numerous moths were noticed b} r the writer at Cabin 
John, Md., between rows of Lima beans, late in the afternoon, hover- 
ing about and alighting upon the blossoms. Some were captured for 
identification, but further observations were not made. During the 
same month and year larvee were observed working on pea pods and 
devouring the peas at Carthagenia and Wooster, Ohio, and in the silk 
of corn at Clifford, Ohio (Webster, 30th An. Rept. Ent. Soc. Ont, 
pp. 56, 57, 1900).
