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.
