HYMENOPTERA.

three apical joints each in succession shorter than the preceding, 

 the apical joint minute. 



The superior wings with one marginal and three submarginal 

 cells, the second and third submarginal cells narrowed towards 

 the marginal, tlie first recurrent nervure uniting with the second 

 transverse cubital nervure. 



The flagellum of the antennae of the male one-third longer 

 than that of the female, but having the basal joint of the flagel- 

 lum shorter than in the other sex. 



This genus in many particulars agrees with that of Anthophora ; 

 the relative proportions of the mentum, labium and palpi are 

 however different, but the neuration of the wings precludes the 

 possibility of placing it in that genus.

Female. Length 6h lines.— Black ; the face clothed with 

 fulvous pubescence, pale at sides, sparing on the clypeus, and 

 darkest on the vertex ; the labrum densely covered with yellow- 

 ish-white pubescence ; the apex of the mandibles fulvo-testaceous. 

 The thorax and basal segment of the abdomen densely clothed 

 with fulvous pubescence above, beneath the former it is paler ; 

 the legs ferruginous, densely clothed above with fulvous pubes- 

 cence, the scopa on the posterior tibia? pale, on the tarsi beneath 

 it is ferruginous ; the wings subhyaline, the nervures ferruginous, 

 the tegulffi pale rufo-testaceous. ^ Abdomen : the apical margins 

 of the segments have fascia? of short yellowish- white pubes- 

 cence ; the fifth and sixth segments have a fringe of longer pu- 

 bescence, which is white at the sides and fulvous in the middle. 



Male.— Closely resembles the female, but having the clypeus, 

 a triangular spot above it, the face on each side, the scape in 

 front, the labrum and mandibles, yellow ; the tips of the latter 

 and the anterior margin of the clypeus ferruginous ; at the base 

 of the clypeus are two quadrate spots united at the base, but 

 not touching the base of the clypeus. The pubescence of the 

 thorax, abdomen and legs as in the other sex ; the anterior coxae 

 armed with an elongate bent spine, which is slightly recurved 

 and thickened at the apex, terminating in an acute point ; all 

 the femora incrassate ; the basal joint of the anterior tarsi have 

 a broadlv dilated quadrate process occupying the apical half be- 

 hind; this process has a row of short curved teeth along its 

 apical margin ; the second joint is armed beneath with an acute 

 tooth ; the basal joint of the posterior tarsi is produced at its 

 apex beneath ; this process is rounded at the extremity.
