Black, shining, thinly clothed with black pubescence; the antennæ beneath, and the apical joints entirely rufo-piceous, tips of the mandibles ferruginous ; thorax, wings hyaline ; the anterior and intermediate tibia and tarsi thinly, and the posterior densely clothed with fulvous hair, the calcaria and apical joint of the tarsi ferruginous ; the margins of the abdominal segments depressed, the apex tufted with brown hair.
Male. — Length 3 — 3¼ lines. Black, shining, with a thin black pu- bescence ; head large, wider than the thorax, sometimes half as wide again ; antennae rufous, with the base black, tips of the mandibles fer- ruginous; thorax, tegulae piceous, wings hyaline, nervures rufo-piceous; the legs nigro-piceous, the posterior femora clavate, with a stout ob- tuse tooth beneath ; the margins of the abdominal segments depressed, the apical segments are tufted laterally with brown hair, the apex bi- lobed.
Panurgus calcaratus I have met with at Charlton, also at Darent in Kent, plentiful at Weybridge, and on several heaths in Hamp- shire ; they frequent different species of dandelion (Leontodon).

They store up a mass of pollen and honey similar to the Andrenidæ.

Apis, Linnæus, Kirby.Trachusa, Jurine.
Antennæ filiform: mandibles with four or five teeth : maxillary palpi 1 -jointed, labial palpi 4-jointed, the two apical joints minute: fore- wings with two complete sub-marginal cells. There is but one British species known.
