Locality and Insect Visitors observed. 
2 Primroses; and another 90 Primroses—all with absolute constancy. 
Two other, medium-sized, brownish Bees visited, respectively, 27 and 22 
Primroses-—both with absolute constancy. Many of the foregoing Bees 
hovered over, but rejected, many Primroses (? long-styled); while, on the 
other hand, on several occasions, I saw a Bee visit a second time a flower it 
had recently visited. 
Wood, Roxwell, Essex.—Between 4 and 5 rw, in a cut-down portion, I 
watched a fair number of Bees, of two species, visit a fair number 
of Primroses. Five individuals of one species, small, blackish, and very 
active in movement (? Anthophora acervorum L.), visited, respectively (1) 
20 Primroses and then two Cowslips (these growing close together), (2) 
9 Primroses (after which a similar Bee arrived and the two flew off together), 
(3) 102 Primroses in quick succession, (4) (? the same individual) 
67 Primroses, also in quick succession (after which, she alighted on a stump 
to re-arrange her load of pollen, subsequently flying away), and (5) 47 Prim- 
roses. Three individuals of the other species, larger and striped (Bombus sp.), 
visited, respectively, (1) 2 Primroses, (2) 18 Primroses, on several different 
plants, and (3) 8 Primroses. 
Same wood as No. 11.—A fine day, but a cold N.E. wind blowing. Extremely 
few Bees visiting the same Primroses, which, though still in flower in vast 
numbers, have passed their best. 
Broom Wood, Chignal, Essex.—T caught two large Humble Bees (Bombus 
pratorum and B, terrestris) visiting Primroses. 
Same wood as Nos. 11 and 12. —At midday, with a cool wind blowing, I saw a 
few Bees (Anthophora acervorum and Bombus sp.) and one or two Bee-flies 
(Bombylius sp.) visiting the same Primroses, now still further past their best. 
Same wood as Nos. 11, 12, and 14.—Saw several middle-sized Bees (? Anthophora 
acervorum) and one of a smaller species (Andrena gwynana) visiting the 
same Primroses (now almost over) with constancy. 
Broom Wood, Chignal, Essex.—Captured one Bombus agrorum Q visiting 
Priniroses 
Broom Wood, Chignal.—During the morning, in an open ride, I watched 
a shabby (evidently hybernated) Peacock Butterfly (Vanessa io L.), which 
visited, within a few minutes, 20 or more Primroses (several of them more 
than once), on five or six different plants, quite obviously sucking nectar from 
most of them. 
Same wood.—Twice, during the day, in a sheltered hollow in which grew a 
great many Primroses, | saw a Peacock (Vanessa io L.)—perhaps the same 
individual—visit 5 or 6 Primroses in quick succession. 
Same wood, —The Primroses are now at their best (a month later than usual), 
but I have not yet been able to detect one single insect of any kind visiting 
them, though I have watehed—this being due, doubtless, to the extremely- 
cold unpleasant weather which prevailed during the preceding weeks. 
Same wood.—A fine, still, warm day. Saw a Peacock (Vanessa io L.) visit 
1 Primrose. Later, saw another visit 7 Primroses in fairly-quick succession, 
Same wood.—In a sheltered glade, watched a Sulphur (Gonepteryx rhamni L.) 
visit 9 Primroses in fairly-quick succession. An hour later, in an adjacent 
glade, watched another (or, perhaps, the same) visit 7 Primroses on adjacent 
plants and depart after searching very obviously, but without success, for more, 
Meadow, Pleshey, Essex.— Watched a large Humble Bee (Bombus Plapidarius) 
busy visiting Primrose flowers.
