Hymenoptera aculeata from Majorca and Spain, 615 



Closely allied to minutissimus, but with a longer face, 

 more shining and rather less closely punctured mesonotum, 

 the central impression of which is shorter and less deep, and 

 with the basal segment of the abdomen punctured ; the 

 propodeum also is narrower and its sides more convergent. 



I have named this species in honour of Mr. W. Holland, 

 who has done so much excellent work on the British 

 insect fauna, and especially the Coleoptera.
