small punctures; pleura striate ; area of metatlurax large^ 

 feebly wrinkled ; tegulse rut'o-testaeeous. Wiii>;s strongly 

 greyish, slightly orange-tinted basally, anterior wings 

 suffusedly blackened at apex; stigma ferruginous; first 

 r. n. joining second s.m. near end; outer r. n, and t.-c. 

 slender; third s.m. much broader than second, third t.-c. 

 with a single curve ; femora with pale hair, but that on 

 tibite and tarsi nearly all black or dark fuscous, more or less 

 whitish on inner side of hind b isitarsi ; hind spur with only 

 very minute short comb-like teeth. Abdomen shining black, 

 with black hair, no bands or patches ; hair on venter 

 whitish, except apically ; first dorsal segment with scattered 

 minute punctures, these in the submarginal region numerous 

 though extremely small: second segment with minute 

 punctures very sparse on disc. 



(J. — Length 10 mm., expanse 18. 



Like the female, but more slender ; clypeus with a very 

 large cream-coloured transverse patch, obtusely angulate in 

 middle above ; antennae very long, entirely black, flagellum 

 strongly creuulate beneath ; area of metathorax much more 

 coarsely sculptured, being thrown into coarse irregular 

 wrinkles ; first and second abdominal segments slightly 

 glaucous (except depressed hind margins), finely and rather 

 closely punctured all over. 



The differences in sculpture of metathorax and abdomen 

 in the two sexes are surprising, but they seem to belong to 

 the same species.

 the male Jan. 31. 



Allied to H, musicus, Ckll., but entirely distinct by the 

 colour of the tegulse, the arrangement of hair on thorax, and 

 sculpture of mesothorax and abdomen. The clypeus of 

 H. musicus is more shining and less densely punctured. 



Halictus pavonellus, sp. n.

Head small, nearly circular, dull dark blue-green, the 

 clypeus mainly black ; head and thorax with thin white 

 hair ; antennae black, the flagellum ferruginous beneath 

 toward apex ; mesothorax and scutellum dull, rich deep 

 blue, rest of thorax very obscure blue-green, posterior trun- 

 cation (which is well defined) bluer ; area of metathorax 

 with fine longitudinal ridges and little cross ones between ; 

 tegulee clear reddish, dark at base. Wings faintly dusky ;
