fourth with whitish hair much as in A. atro-alba female, but less 

 distinct; extreme sides of fifth and sixth segments with white hair; 

 sides of apical half of venter with much light hair; legs dark, including 

 tarsi; outer side of tibse with ferruginous hair; anterior tarsi with 

 light hair, but middle and hind basitarsi with much black hair, 

 especially behind, though they have light hair at apex, and the small 

 joints have light hair, except a black tuft on each side of last joint of 

 middle tarsi; the ornamentation of the middle tarsi is as in A. retusa 

 (not as in A. monacha), except that the posterior black brush of the 

 basitarsus is longer and more or less evidently pointed apically, and 

 the apical black brush seems smaller; face-marks yellow, including 

 clypeus (with no hasal spots), lateral marks (filling space between 

 clypeus and eye, and with an upward process ending a little away 

 from orbit), narrow supraclypeal band, labrum (except the two basal 

 spots) and the rather flattened scape in front; mandibles wholly 

 black; eyes green; flagellum wholly dark; third antennal joint about 

 as long as the next three united; tegulse piceous; wings moderately 

 dusky; third s. m. broader above than second; mesothorax with 

 dense small punctures.

A. retusa Linnaeus is wide spread and very variable, and I was at 

 first inclined to consider the present insect a variety or subspecies.

ANTHOPHORA MELANOGNATHA, new species. 



Male. — Runs in Friese's table to A. senescens Lepeletier, except 

 that it is about 16 mm. long, and has quite the aspect of A.fulvitarsis 

 Brulle. It differs from A. fulvivarsis as follows: Mandibles wholly 

 black; a black band down each side of clypeus; lateral face-marks 

 widely separated from supraclypeal band; yellow area on scape 

 smaller; apical abdominal segments with hair-bands like those on 

 second and third (thus rather combining the features of fulvitarsis 

 and senescens) ; apical spines ferruginous. The legs are practically 

 as in fulvitarsis . From A. senescens (specimen from Cairo compared) 

 it is easily known by the pale bands on the second and third abdomi- 

 nal segments, the whole ornamentation of the basal half of the 

 abdomen being exactly as in fulvitarsis. The face markings are 

 practically as in senescens, but the third antennal joint is shorter.

I give a table for the separation of the above species:
