Extracted from: Cockerell, T.D.A. (1906). Some Bees from Washington State. The Canadian Entomologist pp. 277 - 282.
Female. Length about 12.5 mm.; hind margins of abdominal segments
2 to 4 with very broad light emerald:green tegumentary bands; first
segment with a little green at the hind corners. Closely allied to N.
Foxii: D. T., but larger (though not nearly so large as N. Nortoni), and
differing as follows: anterior part of mesothorax with very pale grayish-ochreous hair, with black bristles intermixed; posterior-part of mesothorax
mainly exposed, shining. impunctate, except for a few large punctures
near the region of pubescence, and scattered scarcely visible rudiments of punctures; scutellum smooth and almost impunctate; apical depression
of first abdominal segment bounded above by a strong ridge, which is
concave toward the depression (in Foxii the depression is less conspicuously bounded, and the boundary is straight); first r. n. entering second
s. m. a little beyond the beginning of its last third. Otherwise Foxii and
Melandri are about the same, but the difference of thoracic sculpture makes the latter a very easily-separated species.
