Hab. Santa Fe, New Mexico; three specimens, July 25th, 1895 in Mr. Boyle’s garden, at flowers of sphaeralecea There is another species with a black clypeus in the male found in New Mexico, M. tristis, Ckll., which I have taken in the Mesilla Valley and at San Marcial. It is easily Known from sphaeralceae thus:— Larger, antennae longer than head and thorax, mandibles with no yellow spot, pubescence of sixth abdominal; species of the Upper Sonoran zone tristis. Smaller, antennae only reaching to metathorax, mandibles with light yellow spot, pubescence of sixth abdominal brown; species of the transition zone sphaeralceae. M. intorta, Cr., from Texas, has the clypeus black in the male, but the abdomen is not banded, and the antennae are shorter than in sphaeralceae.
