Halictus tibialis, Walker, 1871. 
3 .—Type in Brit. Museum. 
Wady Ferran. 
Clypeus strongly produced, shining, with yellow apical 
band ; second s.m. very broad. 
Probably male of distinctus. 
Bombus nasutus, Smith, 1852. 
Meade-Waldo regarded B. breviceps, Sm., as a synonym. 
I examined workers of both in the Wilson Saunders collection 
at Oxford, and, although they are very much alike, I could 
separate them on the malar space, which in breviceps is 
shorter than its apical width, while in nasutus it is longer 
than the apical width. 
Plesianthidium fulvopilosum, Cam., 1905. 
Large and robust; light tegumentary marks only on 
face; sides of abdomen with fulvous or red hair; maxillary 
palpi 3-jointed, second joint robust ; pulvilli present ; second 
r.n. going beyond outer t.-c. 
S. Africa. 
On the venation and palpi the genus would fall as a 
synonym of Paranthidium, T. & W. Ckll., 1901; but it is 
obviously an independent development. 
PROTOANTHIDIUM, Cam., 1902. 
This is not the same as Protanthidium, T. & W. CkIl., 
1901. I saw Cameron’s three species (from Borneo) in the 
British Museum. Al] have the second b.n. going beyond 
outer t.-c., and pulvilli present. ‘They may be transferred to 
Dianthidium, as follows :— 
D. rufobalteatum (Cam.).— Wings dusky, but not bicoloured ; 
antenne long ; clypeus and lateral face-marks chrome- 
yellow, shining. Male. 
D. rufomaculatum (Cam.).—Smaller than ovatum, with the 
stigma clear red, which is not true of the other two. 
On the other hand, it agrees with ovatum in having 
the wings bicoloured, the basal half fuliginous, the 
apical abruptly hyaline, with a rather milky effect. 
D. ovatum (Cam.),
