Mr. Schwarz said, commenting on Miiller's statement that bees 
do not visit white flowers, that Miiller was not speaking of food 
flowers at the time, but what he calls bee flowers. 
Mr. Howard thought that Prof. Riley's experiments, confining 
bees with Yucca which they did not touch, were conclusive. 
Mr. Smith said that the habits of an insect in one locality are 
not necessarily the same as in another. Both Mr. Hulst and Prof. 
Cook had seen bees on Yucca. On Long Island he had found 
Lachnosterna in great abundance on blackberry blossoms. Mr. 
Townsend had found them in Michigan with similar habits. He 
had this season failed to find a single specimen on the flowers 
near Washington, though there were plenty of beetles all around. 
Prof. Riley reasserted the similar fact regarding bees, which 
were often very capricious, but showed that, where they do visit 
the Yucca flowers, they have nothing to do with fertilizing them, 
and, even in artificial pollination by man, perfect fruit can only 
be obtained when the pollination is done as fully and carefully as 
it is done by Pronuba. 
Prof. Riley read the following paper : 
Two BRILLIANT AND INTERESTING MICRO-LEPIDOPTERA NEW TO OUR 
FAUNA. 
BY C. V RILEY. 
I have had for some time, as a part of the material which I have turned 
over to the National Museum, two small moths of exceptional brilliancy 
and beauty, which are new to our fauna and which I took occasion to study 
while in Europe last autumn. As a rule, I do not care to present isolated 
descriptions of species, but in both these instances there are special rea- 
sons for departing from this rule, as the first is one of the largest and pret- 
tiest of the Tineina, having a superficial Tortricid habitus, and the second 
is interesting as belonging to a small group essentially exotic, which has 
been placed by authors both in the Tineidae and the Tortricidae, and which 
virtually is a somewhat interesting form belonging rather to the lower 
Noctuidee. I name them in honor of two of our most capable and most 
worthy micro-lepidopterists, and in each case with permission. 
SETIOSTOMA FERNALDELLA n. sp. Expanse, 12-13 mm. General col- 
ors, vivid pea-green, yellow, and metallic bronze. Head, vivid pea-green, 
approaching in some instances to olivaceous ; face and palpi paler, more 
yellowish. Thorax of the same vivid green, somewhat more yellowish on 
the borders, but especially on the collar, which is separated from the meso- 
thorax by a fine black suture. Primaries of the same vivid green at basal 
third, posteriorly limited by a straight line which slightly obliques outwardly
