On Bees in the Collection of the British Museum. 203 



XXIX. — New and little-known Bees in the Collection of the 

 British Museum. By T. D. A. Cockerell. 



Anthoglossa cygni, sp. n. 



? . — Length about \b\ mm. 



Allied to plu7nata, Smith, and with the same broad second 

 submarginal cell, but differing thus : — Hair on fifth and apical 

 segments of abdomen brown-black (in plumata orange-fulvous 

 on fifth) ; abdomen without bands of any sort, but first 

 segment with white hair laterally, and thin white appressed 

 pubescence on hind margin ; hair of sides of mesothorax not 

 tipped with black ; mandibles with outer edge convex, but 

 not at all elbowed, and having two short denticles within ; 

 labrum shining, ferruginous ; face covered with long hair ; 

 flagellum ferruginous beneath, except first joint, last joint 

 ferruginous above, with a shining oblique truncation (last joint 

 is red also in plumata). 



The other species, A. sericea, Sm,, is distinguished from 

 plumata and cygni by the thorax being without plumose 

 black-tipped hairs, and the second submarginal cell greatly 

 contracted above. 



A. cygni is from Swan River, W. Australia. 



Leioproctus Boltoni, sp. n. 



? . — Length 11^ mm. 



Shining black with pale greyish-ochreous pubescence, with 

 some black, noticeably on hind part of scutellum, fifth and 

 apical segments of abdomen, and basal part of the long scopa 

 of hind tibia?. Head broad, facial quadrangle broader than 

 long j clypeus nude, wath coarse large punctures ; mesothorax 

 shiny, not strongly punctured ; tegulas shining piceous ; 

 base of metathorax moderately shining, transversely obtusely 

 ridged, its marginal furrow with only minute rather obscure 

 cross-ridges ; stigma large but narrow, it and the nervures 

 dark brown. 



S . — Similar but smaller, with longer antennse, which are 

 entirely black. 



Hal. New Zealand [Col. Bolton, 1854). 



This is a Basycolletes, but I am unable to separate that 

 genus from Leioproctus. It differs from Leioproctus metallicus 

 {Dasycolletes metallicus, Smith) by the absence of green colour 

 on the abdomen, black hair at apex of abdomen and on base 

 of hind tibice, rather longer and narrower abdomen, &c. From
