810 THE AMERICAN NATURALIST. [Vor. XXXVI. 
Although our common types of Verbena (V. macdougalii, V. bipinnati- 
fida, and V. bracteosa) look so entirely different, they all have the 
throat of the corolla covered with the same peculiar moniliform hairs. 
V. macdougalii is an excellent bee plant. On the Rio Ruidoso, Town- 
send collected from the flowers the following bees: Anthophora 
cleomis Ckl. 9, A. montana Cress. 9, Clisodon terminalis Cress., 
Anthidium maculosum Cress., Anthophora californica Cress. 8, 
Megachile fortis Cress., Melissodes ruidosensis 5 t 
crenulaticornis Ckll. $, Calliopsis rhodophilus Ckl. 9. It will be 
noted that these are long-tongued bees. 
(2) Monarda stricta Wooton. Another very common New Mexico plant, 
only lately recognized as a distinct species. Its conspicuous heads 
of pink flowers are attractive to certain long-tongued bees, of which 
Townsend collected Anthophora cardui Ckl. $, A. cleomis Ckll. d, 
Clisodon terminalis Cress., and Megachile fortis Cress. The flowers 
are also visited by Bombus, as I have recorded elsewhere (Annals 
and Magazine Natural History, November, 1899), and Town- 
send took a single male Melissodes montana Cress. He also took 
a butterfly, Epargyreus fityrus Fabr., not hitherto recorded from 
New Mexico. These results accord fairly well with those of Loew, 
who observed the insect visitors of Monarda in the Botanic Garden 

at Berlin. 
Bombus. Other long-tongued bees. Short-tongued bees. Butterflies.

Both lists are doubtless very incomplete. 
(3) Rhus glabra L. A widely distributed shrub, with conspicuous panicles 
of greenish flowers. The visitors might be expected to be much like 
those of the Umbelliferz, but Townsend actually obtained a number 
of bees: Bombus sonorus Say, B. prunelle@ Ckll, Colletes gilensis 
Ckl. 3, Coelioxys gilensis Ckll, Heriades gracilior Ckll., Colletes 
americana Cress. $. He also obtained a butterfly, Basz/arcAza weide- 
meyerit Edw. In Europe Müller found the honeybee abundant on 
the allied Rhus hirta. ln Illinois Robertson found fifty-eight species 
of insects on x Reto of which nineteen were bees, mostly short- 
tongued. 
(4) Potentilla thurberi Gray. This is a beautiful species, differing from 
ie ordinary species of the genus by its dark crimson flowers, on which 
. Townsend took the following : ro fortis Cr., Colletes gülensis 
Ckll. 8, Vespa occidentalis C 
(5) Geranium atropurpureum Heller. A common New Mexico plant, 
only r recently recognized as distinct. Visited by males of Co//efes 
qs CklL, a short-tongued bee. -
