312 THE ZOOLOGIST. 
(4). Helianthus annuus; visited by Perdita albipennis var. hyalina 
(Cr.), Pseudopanurgus ethiops (Cr.) Melissodes agilis, Cr., Andrena 
helianthi, Rob. (new to N. M.), and Nomia persimilis, Ckll. ined., 
@. The females of Nomia persimilis mimic Andrena helianthi 
to such a degree that when collecting them I did not distinguish 
the two species. 
(5). Asper sp. with purple rays; visited by males of Nomia persimilis, 
Ckll. ined. 
There is one thing to be noticed in connection with the above records, 
namely, that the flowers which attracted the bees are not only of bright 
colours, but occur in large masses, so as to be visible from a distance. The 
other eleven flowers are either comparatively inconspicuous, or do not occur 
in large masses, except perhaps.the Anemiopsis, which seems quite unsuited 
for bees. :

The end of the bee season was at hand, and few species were on the 
wing. Bigelovia or Chrysothamnus spectosus var.? latisquameus (det. KH. O. 
Wooton) was still in flower, and attracted Halictus ligatus, Say, 3, Colletes 
americana, Cr., 2, and females of Melissodes, besides some undetermined 
males of Halictus. In a garden, marigolds and marguerites were yet in 
bloom, and I watched them with interest because, although garden flowers 
are usually unattractive to wild bees, they are visited when the wild flowers 
are mostly over, at the end of the summer. The result was as follows :— 
(1). Marigolds; visited by males of Halictus ligatus, Say, and males 
and females of some small species of Halictus not yet studied. 
(2). Marguerite; visited by one 2 Perdita snowii, Ckll. This was a 
most interesting capture, as the species was hitherto known only 
by a unique specimen taken in Colorado. On Oct. 2nd I took 
at the marguerite a 2 Perdita zebrata, Cr. (which normally visits 
Cleome), anda @ Halictus. 
A single patch of the wild golden-rod (Solidago canadensis), almost over, 
was visited by a 9? Halictus on Sept. 20th. 
Espanola, N. M., Sept. 25th. 
Two males of Halictus were taken while the train stopped. There 
were found here, close to the station, not only the common Xanthium cana- 
dense, but a quite different species of Xanthium, which to my surprise is 
reported by Prof. Wooton as differing from anything in the herbarium of 
Columbia University.
