 antennae long, joints 4 to 9 clear feriuginous beneath ; head 

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

 and scutellum closely and finely punctured, somewhat 

 glistening ; area of metathorax finely rugose, posterior

$ . — About 12 mm. long. 



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

 ments ; posterior truncation of metathorax nowhere sharply 

 defined, longitudinal striae 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

j\ladeira (7'..F. WoUaston). Oxford Museum. 



This stands in the Wollaston collection as H. quadri- 

 strlgatus, Latr. (which is quadricinctus, Fabr.), and is closely 

 allied to that variable species, j-et evidently distinct, espe- 

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

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

 it was distinct from quadristrigatus. Another female stands 

 in the collection as H. zeh'us, 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 pubescens, Friese, from Costa Rica, is represented 

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

 is identical with a Neocorynura from Costa Rica named 

 years ago by Vachal, but, so far as I can find, not published.
