Becords of Bees. 307 



nervure near the begin uing of its last third. Tarsi dark 

 reddish ; hair on inner side of basal joint of hind tarsi 

 (which is rather broad^ with the outer apical corner produced 

 to an acute angle) shining ochreous ; second joint of hind 

 tarsi triangular, the apex produced like that of first joint. 

 Abdomen shining, with a rather sericeous surface, the 

 punctures obscure ; hind margins of segments rufescent, 

 those of third and fourth with broad, dense^ entire fulvo- 

 ochraceous hair-bands ; on the first and second these bands 

 only appear laterally, or the band may be nearly complete on 

 the second ; fringe on fifth segment redder ; ventral seg- 

 ments fringed with very long hair. 



Hub. Queensland, four specimens [Gilbert Turner). They 

 all bear the collector's number 313. 



Nomia halictella, var. triangvlaris, nov. 



? . — A little larger (expanse of wings 18 mm.). Stigma 

 dark reddish ; basal enclosui'e of metathorax much larger in 

 the middle, being produced behind to form a large triangle, 

 which is covered with longitudinal ridges, which are not so 

 fine as those of the type. 



This insect is a very puzzling one : the enclosure of meta- 

 thorax is so different from that of typical halictella, that one 

 would take it for a distinct species ; but in all other respects 

 the insect is essentially halictella. 



Hab. Queensland {Gilbert Turner), marked 311 Hy. 



Halictus urbanus baudinensis, subsp. n. 



? . — Length about 5 mm. Similar to urbanus, with the 

 same peacock-green mesothorax ; but tibi?e and tarsi, and 

 apical third or fourth of femora, all bright ferruginous ; 

 hind spur with two long spines ; hind femora somewhat 

 deformed, appearing as though bent near the middle ; stigma 

 very dark reddish brown ; first r. n. meeting second t,-c. ; 

 tegulse shining fulvous; abdomen beyond the first segment 

 delicately white-pruinose. 



Hab. Baudin I., N.W. Australia {J. J. Walker, 675). 

 Collected on the 'Penguin^ Expedition. 



This is very likely a distinct species, but it is very close to 

 H. urbanus, and may be treated as a subspecies until more 

 material has been collected. It has the outer nervures 

 weakened, as in Cldoralictus.
