During his travels in 1890 and 1891 in the väst terri- 

 tories of the Cameroons in "West Africa Professor Yngve Sjö- 

 stedt collected a small number of hymenoptera. Among these the 

 group Aculeata was the best represented one in reference to 

 the nnmber and he has been so kind as to snbmit to me the 

 examination of them except the Apides, a work that has been 

 made a possibility through an allowance from the Royal Swe- 

 dish Academy of Science.

 19 ones are new for Science. They are all collected in the
