335 Die Bienen Afrikas nach dem Stande unserer heutigen Kenntnisse. , ,- 



notum. Apical segrnent thickl)' covered with long silvery hair. Metatarsus narrower than the tibiae. Clypeus 

 not very flat. Hind ocelli separated from the eyes by a distinctly greater distance than they are from 

 each other.

Anthidiuni eurysoniuni Cam. 

 1905 Anthidium eurysomum Camehon, $, in: Reo. Albany Mus., Vol. I, p. 202. 



?. Black, the clypeus, the lovver half of the inner orbits broadly and mandibles except the teeth, pale 

 yellow; a spot on the outer side of the basal two abdominal segments, narrow lines towards the middle of the 

 third and fourth, a large broader line, transverse on the inner side, narrowed towards the outer, and a larger 

 line Oll the outer side of the 51h, lemon-yellow. Four front tarsi white; the fore tibiae anteriorly testaceous, 

 their apex and tliat of the middle pair pale testaceous, the apex of the hind tibiae also testaceous. Wings 

 fuscous-violaceous, with hyaline clouds; the tegulae black. L. 7 mm, br. 3 mm. 



Mandibles tridentate, the apical tooth long and curved, the basal two shorter, broader and bluntly rounded. 

 Apex of clypeus transverse, its sides rounded. The clypeus and face covered with long white hair, the front 

 with darker, the Vertex and occiput with dark fulvous hair. The hair on the top of thorax dark fulvous, on the 

 pleurae white ; as is also the case with the hair on the ventral surface. Apex of last abdominal segrnent bluntly, 

 shortly bidentate, the incision between the two shallow. Apex of clypeus broadly rounded, projecting. Hair on 

 legs long and clear white: calcaria pale testaceous. The second recurrent nervure is almost interstitial ; there is 

 a white line on the apex of the antennal scape below. Metatarsus narrower than tibiae. The 2nd abscissa of 

 radius distinctly shorter than the ist. 



This species agrees closely with A. crassidens, but can hardly be its male, the structural diffcrence be- 

 tween the two being too great. The two may be separated thus: 



Mandibular teeth four, the apical not greatly longer and sharper than the others; apex of scutellum with a 

 slight but distinct incision in the middle; second abscissa of radius equal in length to the first . crassidens. 



Mandibular teeth three, the apical much longer and sharper than the others, apex of scuteUum not incised ; second 



abscissa of radius clearly shorter than the first eurysomum.

Anthidiuni melanosomuni Cam. 

 1905 Anthidium melanosomum Cambron, $, in: Rec. Albany Mus., Vol. I, p. 200. 



?. Entirely black, except the apical joints of the four front tarsi, which are rufous, the tarsi above thickly 

 covered with pure white pubescence, below with dark rufous ; the front with long white hair, vertex, face, clypeus 

 and the upper part of thorax with fuscous, pleurae niore densely witii longer white hair, poUenbrush white; 

 wings hyaline, with distinct fuscous-violaceous tinge, nervures and stigma black. L. 8 mm, br. 3 mm. 



Mandibles 4-dentate, 4. tooth the smallest, the 2. shorter than the i. or 3. Head and thorax closely 

 strongly punctured, clypeus more closely than the rest; apex of clypeus broadly rounded, almost transverse; apex 

 of clypeus transverse with the sides rounded, apical slope smooth, impunctate, hardly projecting; tegulae black, 

 smooth and shining. 



Smith describes (1854) an entirely black species (A. Immaculata) from the Cape, but its description, such 

 as it is, does not fit the species I have described.
