A454 On North-American Bees. 
upper part encloses a triangular space which is emarginate 
behind and produced and much narrowed in front; from the 
emargination runs a light line dividing the space longitudi- 
nally ; the lower (posterior) ends of the A enclose the lateral 
ocelli ; the scutellum presents on a black field two median 
rather short bars, a large apical subreniform spot, two small 
lateral spots, and anterior to these two rather large oblong 
marks, of these markings the last mentioned being orange- 
vermilion and the others lilac; underside of abdomen lilac, 
with black at the bases of the segments; elytra green in life, 
but in a dry specimen purplish grey by reflected and deep 
rose-pink by transmitted light ; the costa very narrowly dull 
orange; a large, very irregular, pale green patch next to the 
costa about the middle of the elytron, and touching it ante- 
riorly a short black bar ; apical field smoky hyaline bordered 
with black, the black next to the purple-grey rather broadly 
edged on the inner side with chrome-yellow. Plates of 3g 
genitalia somewhat longer than in Ball’s figure of typical 
undata. 
Hab. Dripping Spring, Organ Mts., N. M., frequent on 
Garrya Wrightit. 
I could not find any, or any other form of O. undata, on 
other plants in the Organ Mts., and I believe the insect is 
restricted to the Garrya, with which its colours harmonize 
well. Mr. O. Heidemann kindly examined a specimen, and 
considered it near O. a/pha, Fowler, which Mr. Ball considers 
a mere form of O. undata. I suspect that we should under- 
stand better the many varieties or subspecies of O. undata 
if in every case we knew the food-plant.

Another new Anthophora. 
Much to my surprise a second new Anthophora has been 
caught in this vicinity this spring. 
Anthophora Gohrmane, sp. n.

Black ; the abdomen with a slight bluish lustre, the hind 
margins of the segments narrowly brown ; tongue compara- 
tively short, about 6 millim. long ; two apical joints of maxil- 
lary palpi very small; mandibles black ; eyes deep olive-
