hair-bands, strongly and extremely closely punctured, hind margins of 
segments not at all greenish. The male has the hind tibiae broad and 
flattened, the inner apical corner produced into a blunt spine. 
I first met with this species on the morning of Sept, ii, 1895, ^ 
sandy place in the Mesilla Valley, near to the Agricultural College. The 
females were very abundant, flying over the sand like bembecides; mak- 
ing deep, large burrows straight down in the sand, and throwing up 
quite conspicuous piles of earth. Some were heavily loaded with orange 
pollen. All were females, and without the male I could not tell whether 
the species belonged to Nomia or Eunomia. Next, Prof. L. Bruner sent 
me a single female collected at Lincoln, Nebraska, in August. In Al- 
buquerque I met with the species between the old and new towns. Sept. 
16, and took three males and four females. The males enable me to re- 
fer the insect to Nomia, of which it is a very distinct new species. It is 
curious that all the males were on an Aste?' with purple rays, while the 
females were at the flowers of Helianthus annuiis, gathering pollen. The 
females have the strongest possible superficial resemblance to Andreiia 
helianthi, which was visiting the same flowers, so that when collecting I 
had no idea that there were two species before me.
