Hymenoptera aculeata collected in Algeria. 537 



once distinguish it from maura. The punctures in this species are 

 as a rule further apart than the width of each individual puncture, 

 whereas in maura and in most of the other species they are so 

 crowded as almost to become confluent. The abdomen also in this 

 species is less strongly and closely punctured than usual, the punc- 

 turation of that of the $ being very sparse and fine. It really 

 seems to me to be most closely allied to 4 punctata and dispar, 

 but its entirely black livery and its less close puncturation will 

 distinguish it from the black-winged variety of the former, and 

 the black hairing of the male and entirely black livery of both sexes 

 separate it from dispar.
