GENERAL OBSERVATIONS. 
Named by St. Fargeau from avdos, a flower, and 
Koirr), a cutting or incision, from its habit of cutting sec¬ 
tions out of the petals of the common scarlet poppy with 
which to line the cells it forms within the cylinder it 
excavates, just as Megachile does with the leaves of 
various plants. It is noticed as British upon the faith 
of the specimens introduced by Leach into the cabinets 
of the British Museum and presumptively caught in the 
west or south-west of England, a region rich in rarities. 
Bennie in fact tells us that he has found it at Largs, in 
Scotland. One of Leaclds specimens I received in ex¬ 
change from that establishment in 1842, and which is 
now in the possession of Mr. Desvignes, to whom my 
collections passed in the following year. This genus 
forms a sort of combination between the genera Mega¬ 
chile and Osmia, it having the upholstering habits of the 
former in the mode with which it lines its nest, and the 
general habit of the latter. At a first glance, before its 
habits were known or its structure examined, even an 
experienced entomologist might have placed it under Os¬ 
mia, as an unrecognised species, for it very strongly re¬ 
sembles the Osmia leucomelana. This proves how very 
inconclusive habit is as an index to habits, the latter of 
these insects drilling into the pith of brambles, and the 
Anthocopa tunnelling cylinders into the hardest trodden 
roads or pathways and lining them with its crimson hang¬ 
ings.
