tlian broad, orbits nearly parallel; front dull and granular; 

 antennse long, joints 4 to 9 clear ferruginous beneath ; head 

 and thorax with long, thin^ pale fulvous hair ; mesothorax 

 and seutellum closely and finely punctured, somewhat 

 glistening ; area of metathorax finely rugose, posterior 

 truncation not detined; tegulse dark rufous, with a piceous 

 spot. Wings faintly reddish, stigma bright ferruginous, 

 nervures fuscous ; third s.m. long, fully as broad on mar- 

 ginal as second ; second s.m. about square, receiving r. n. 

 beyond middle; outer r. n. and t.-c. strong. Legs black, 

 with knees, tibiae, and tarsi ferruginous ; hind tibias with a 

 very faint dusky shade posteriorly. Abdomen glistening, 

 extremely finely punctured, hind margins of segments with 

 dull white hair-bands. 



? . — About 12 mm. long. 



Robust ; hair-bands confined to sides of abdominal seg- 

 ments ; posterior truncation of metathorax nowhere si)arply 

 defined, longitudinal striee on each side of its median sulcus ; 

 area of metathorax with coarse rugose hide-like sculpture ; 

 clypeus shining, with large punctures, flagellum very 

 obscurely reddish beneath ; hind spur with five erect saw-like 

 teeth; third s.m. not quite so broad on marginal as second; 

 surface of abdomen thinly hairy, first segment shining.

Madeira (T. V. Wollastoti). Oxford Museum. 



Tliis stands in the Wolhiston. collection as U. quadri- 

 str'jgatus, Latr. (vvliich is quadricinctus, Fabr.), and is closely 

 allied to that variable species, yet evidently distinct, espe- 

 cially by the dark clypeus in the male. It was examined 

 years ago by E. Saunders and Vachal, and they agreed that 

 it was distinct from quadristrigatus. Another female stands 

 in the collection as H. zebrus, Walck. ; it is not so large, the 

 mesothorax is more finely sculptured, but the hind legs have 

 the same fulvous hair and the same spurs. After careful 

 comparisons I concluded that all the specimens represented a 

 single species. 



Neocorynura puhescens (Friese). 



Halictus puhescens^ Friese, from Costa Rica, is represented 

 in the U.S. National Museum by material from Friese. It 

 is identical with a Neocori^nicra from Costa Rica named 

 years ago b)^ Vachal, but, so far as I can find, not published. 



Thorax emerald-green, the mesothorax with short moss-like
