PAIRING HABITS. — Both sexes of all of the species 
were found. Thirty pairs belonging to eight species were taken 
in copula. The differences are remarkable. Of eight species 
no pairs were seen together, while of Calliopsis coloradensis, 
which flies only 36 days and visits only five flowers, seven pairs 
were taken together, forming a majority of the specimens. 
VISITS TO FLOWER CLASSES.— The table shows 144 
visits to 85 flowers. Mas shows 37.6 per cent, of the flowers visit- 
ed and 45.1 per cent, of the visits. Red shows 35.2 per cent, of 
the flowers visited, while yellow shows 49.3 per cent, of the visits. 
Ccdliopsis andreniformis , with 35.4 per cent, of the total visits, 
shows 29.4 to Mas and 43.1 to red. Separating this species the 
remaining 15 show for Mas 51.1 per cent, of the flowers and 53.7 
per cent, of the visits, and for yellow 53.3 per cent, of the flowers 
and 67.7 per cent, of the visits. Seven species, C. coloradensis- 
P. solidaginis, show 78.4 per cent, of their visits to Mas and 90.1 
to yellow. The last five show 63.8 per cent, under Mis and 44.4 
under white. As a rule the visits of the males do not differ much 
from those of the females, but in Calliopsis andreniformis the 
male shows 5.8 less in percentage of visits to Mas, 11.0 less red 
and 14.9 more to white.
